Description

 Description: Phosphorescent paper, method for producing the same, and method of using the same

 (1) The present invention relates to a phosphorescent paper, a method for producing the same, and a method for using the same.

 Background art

 Conventionally, there are various products using a luminous pigment. For example, a display plate, a decorative plate, a luminous pigment-added spray, brush painting, brushing various luminous paints, a luminous pigment-added adhesive or an adhesive sheet, or a plastic plate mixed with a luminous pigment. There is a special ink for screen printing with the addition of luminous paint.

 The phosphorescent substance emits light by itself after excluding external energy excitation, but has a long light emission duration. The phosphorescent substance emits light by absorbing ultraviolet rays. The pigment composed of such a phosphorescent substance is herein referred to as a phosphorescent pigment. Also, the absorption of ultraviolet light by the luminous substance is called luminous storage, and the luminescence in which the luminous substance emits light after stopping the irradiation of ultraviolet light is called afterglow. By the way, the fluorescent substance emits light by itself after excluding external energy excitation, but the luminous duration is much shorter than that of the phosphorescent substance. The fluorescent substance emits light by absorbing visible light. A pigment made of a fluorescent substance is called a fluorescent pigment.

 Recently, various types of luminous pigments have been commercialized. In particular, luminous pigments made of strontium aluminate (SrA124) doped with various rare earth elements are visible. Products that have various emission wavelengths in light, have high luminous efficiency, and emit light after excluding external energy excitation, that is, have extremely long persistence, have been commercialized. For example, a luminous pigment made of strontium aluminate, after being saturated and absorbed by irradiation with ultraviolet light, has an afterglow of about 200 minutes. Thus, recent phosphorescent pigments have excellent properties such as having various emission wavelengths and a long afterglow duration. However, although it is a phosphorescent pigment having such excellent properties, applied technology has not been developed much.

Luminescent pigments are generally crystalline particles made of an inorganic substance and are insoluble in water and oil. In addition, if the size is not larger than a certain size, there is a property that the luminous efficiency is small. In particular, the specific gravity is large. The phosphorescent particles are heavy and hard, and therefore have a property that they are easy to settle in a liquid. For this reason, it is difficult to disperse and fix the phosphorescent pigment at a uniform concentration in various materials, For example, a plastic display with a phosphorescent pigment added; in the case of manufacturing decorative plates, a phosphorescent material is added to a molten plastic material, mixed well to disperse the phosphorescent pigment, and quickly before the phosphorescent pigment settles. A manufacturing method called solidification is used. However, when a luminous pigment is dispersed in an organic substance, the luminous intensity of the luminous pigment is reduced because the organic substance easily absorbs ultraviolet rays, and thus is not widely used at present.

 In addition, plant fibers or synthetic fibers that are entangled flat, that is, phosphorescent paper formed by fixing phosphorescent pigment on paper, are heavily phosphorescent and insoluble, so plant fiber, It is impossible to settle on synthetic fibers, and it has not been realized until now. That is, even if the paper is dissolved in water, the fibers constituting the paper are uniformly dispersed, the luminous pigment is uniformly dispersed in the aqueous solution, and the luminous pigment is uniformly fixed by removing the water to make a luminous paper. However, since the luminous pigment was heavy and insoluble in water, the luminous pigment quickly settled through the gaps in the paper fibers, making it impossible to fix the luminous pigment on paper.

 If paper with phosphorescent pigment fixed (in the present invention, this is referred to as “phosphorescent paper”) can be realized, the application technology of phosphorescent pigments will spread at a stretch, and conventional problems in various fields can be solved. .

 For example, in the medical field, phototherapy, photochemotherapy and the like have been conventionally performed. For example, treatments to irradiate ultraviolet rays to the skin are used to treat rickets and promote the production of vitamin D, and treatments to irradiate the skin with visible light are used to treat jaundice in newborns. In addition, treatment of skin cancer, vitiligo vulgaris, and atopic dermatosis is carried out by irradiating the skin with ultraviolet light, etc., by incorporating a photosensitive sensitizer from outside the body (eg, Nanzando Medical Dictionary) , 1999, January 30, 2nd print, page 3110).

 The light source used for these phototherapy and photochemotherapy is, for example, a treatment lamp of 400-500 nm for the treatment of jaundice in newborns (for example, "Light is active" by Yuzo Sakuma, 1993) The first edition of the first edition was published on March 31st, see page 234. Also, carbon light arc lamps were used for private phototherapy (for example, "National Dictionary of Health" by Naoki Fujii, 1982). The second edition of the first edition was published on March 25, see page 48).

However, in these phototherapy and photochemotherapy, it is necessary to turn on the light source using electricity and expose the skin to glitter. Therefore, it always requires commercial power and cannot move during treatment. For this reason, a section saying that they could not receive treatment even if phototherapy and photochemotherapy were effective because they said they were busy and had no time to receive treatment There was a title.

 Therefore, an object of the present invention is to provide a phosphorescent paper which can be applied to various uses having a high luminous intensity in which the phosphorescent pigment is uniformly fixed on the paper.

 Another object of the present invention is to provide a method for producing such a phosphorescent paper.

 It is a further object of the present invention to provide a method for using these phosphorescent papers. Disclosure of the invention

Adhesive tape is stuck on the light transmissive layer, and the phosphorescent paper is hardly damaged even if the stuck adhesive tape is peeled off. Thus, for example, it can be used as a phosphorescent paper for visible light treatment. Also, when the light-transmitting layer is made of transparent rayon paper, there is little bleeding in water and organic solvents, so if a fluorescent paint is printed on the transparent rayon paper of the phosphorescent paper, a high-definition image can be printed. For example, it can be used as printing paper for fluorescent paint printing.

The strength is increased. For example, the phosphorescent paper is hardly damaged even if a cotton cloth is applied on a viscous resin layer or a synthetic rubber layer, an adhesive tape is applied on the cotton cloth, and the applied adhesive tape is peeled off. Therefore, it can be used, for example, as a phosphorescent paper for visible light treatment.

In order to solve the above-mentioned problems, the present invention provides a method of mixing finely-divided paper, a foaming agent, and a luminous pigment into an aqueous solution, and stirring the aqueous solution to generate bubbles to which the luminous pigment adheres, and And a paper fiber, and mixing the mixed solution in a mold container having a bottom surface made of a nonwoven fabric, and dehydrating the water content of the mixed solution through the nonwoven fabric to obtain the phosphorescent paper. Is provided. According to this configuration, the foam having the phosphorescent pigment adhered to the surface is generated by the foaming agent, and the foam having the phosphorescent pigment adhered to the surface receives buoyancy in the aqueous solution and is uniformly distributed. It does not settle in the aqueous solution, mixes evenly with the paper fibers evenly distributed in the aqueous solution, and the phosphorescent pigment and the paper fibers are uniform To form a mixed solution.

 In order to solve the above-mentioned problems, the present invention provides a method of mixing finely-divided paper, a foaming agent, and a luminous pigment into an aqueous solution, and stirring the aqueous solution to generate bubbles to which the luminous pigment adheres, and And the fibers of the paper are mixed, and the mixed liquid is placed in a mold container having translucent rayon paper laid on the bottom surface of the nonwoven fabric, and the moisture of the mixed liquid is dehydrated through the nonwoven fabric. It is intended to provide a method for manufacturing a phosphorescent paper characterized by obtaining. According to this configuration, in addition to the above-mentioned functions and effects, a luminous paper is produced, which is durable and has little bleeding with respect to water or a solvent, in which the luminous pigment is deposited with a uniform distribution in the surface direction and the thickness direction of the paper. Therefore, it is suitable for phototherapy and printing. In this configuration, it is necessary that the foam generating agent generates bubbles to which the luminous pigment is attached and has a strength that does not cause the bubbles to collapse during the manufacturing process. For example, foam generating agents are aqueous sealers and pastes, especially aqueous sealers. The aqueous sealer may include, for example, an aqueous acrylic resin and Z or silicone. As the paste, starch-based, cellulose derivative-based or synthetic laundry paste is suitable. In addition, in the step of putting the mixed solution into the mold container, the mixed solution held in the cylindrical container having a predetermined diameter is dropped from a predetermined height while holding the cylindrical container vertically at the center of the mold container, and the flow rate is controlled. And put it in. As a result, the mixed solution can be poured into the mold container with a uniform thickness without eliminating bubbles having the phosphorescent pigment adhered to the surface. In the step of dehydrating water from the mixed solution, dehydration is performed by controlling the dewatering rate using a nonwoven fabric having an appropriate gap and thickness. This prevents bubbles from collapsing during dehydration and sedimentation of the phosphorescent pigment. The member for controlling the dewatering speed may be a porous member capable of uniformly controlling the dewatering speed over the entire mold container, and may be, for example, a nonwoven fabric.

 In the above cases, the mixed solution preferably has a water temperature in the range of 18 ° C to 22 ° C.

 In this way, it is possible to manufacture a phosphorescent paper in which the phosphorescent pigment is fixed with a uniform distribution in the surface direction and the thickness direction of the paper.

Further, in order to solve the above-mentioned problems, the present invention provides a paper layer in which vegetable fibers or synthetic fibers are entangled and flattened to fix a luminous pigment to form a paper layer, and light is transmitted through one side of the paper layer. A method for producing a phosphorescent paper, characterized by providing a layer, and applying or sticking a viscous resin layer or a synthetic rubber layer having optical transparency on the side on which the optically transparent layer is provided. . According to this method, light emission irregularly reflected by the fibers of the light storage paper is collected, and a light storage paper having a high uniform light emission feeling can be manufactured. Further, in order to solve the above-mentioned problems, the present invention is characterized in that the phosphorescent paper is irradiated with ultraviolet light, this ultraviolet light is converted into visible light to emit light, and the afterglow of the light emission is irradiated on the skin. It is intended to provide a method of using phosphorescent paper. At this time, the phosphorescent paper can be fixed to the skin by bringing the surface of the phosphorescent paper into close contact with the skin, and attaching the transparent adhesive tape material to the surface of the transparent rayon paper on the back and the skin. According to this configuration, under sunlight, the luminous pigment of the luminous paper absorbs the ultraviolet rays of the sun rays and converts them into light of a predetermined wavelength to irradiate the affected part. If it is under a fluorescent light, the luminous pigment of the luminous paper absorbs the ultraviolet light of the light of the fluorescent light, converts it into light of a predetermined wavelength, and irradiates the affected part. In the absence of light, such as when sleeping, the phosphorescent pigment of the phosphorescent paper irradiates the affected area with afterglow. In addition, since the emission wavelength can be selected by selecting the type of the phosphorescent pigment, various light treatments suitable for the purpose of treatment can be performed.

It is preferable that the cloth is bonded to reflect the afterglow luminance, and the skin is irradiated with the afterglow of the reflected light having the afterglow luminance.

 In this way, by using the phototherapy method using the phosphorescent paper of the present invention, phototherapy can be performed irrespective of location and time, and even while working. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, substantial The same members will be described with the same reference numerals.

 First, a first embodiment of the phosphorescent paper of the present invention will be described.

 FIG. 1 is a schematic cross-sectional view showing a configuration of a phosphorescent paper according to a first embodiment of the present invention, and the unevenness and the depth are drawn quite exaggeratedly.

 In FIG. 1 (A), a luminous paper 1 of the present invention is composed of a paper 2 in which paper fibers (web) are entangled, and a luminous pigment 3 fixed to the paper fibers of the paper 2. In addition, the depression 4 is a trace of bubbles generated by the production method described below.

 Paper 2 is made of plant fiber or synthetic fiber such as cellulose, and phosphorescent pigment 3 is made of zinc sulfide (ZnS), calcium sulfide (CaS), and rare earth element-doped strontium aluminate (SrA1 204: Eu). Strontium aluminate (Sr4A114025: Eu, Dy), or rare earth element-doped calcium aluminate (CaA1204: Eu, Nd). In particular, rare earth element-doped strontium aluminate phosphorescent pigments are sold in addition to the above rare earth elements, and the emission wavelength changes depending on the type of rare earth element to be dropped. However, the emission wavelength can be changed over almost the entire visible light range, and the afterglow after saturation light storage is long.

 As shown in FIG. 1 (A), in the phosphorescent paper 1 of the present invention, the phosphorescent pigment 3 is fixed at a substantially uniform concentration in the thickness direction and the surface direction of the phosphorescent paper 1.

Here, instead of resin or soft resin, luminous pigment is entangled with vegetable fiber or synthetic fiber and fixed and molded. In the case of grease, for example, acrylic, polyethylene, polystyrene, polypropylene, polycarbonate, ABS , polyacetal, urethane, etc., from the relationship of the intensity, the amount of phosphorescent pigment is 30% position is the limit, in the case of soft-emitting layer, the addition amount of the phosphorescent pigment, a 300 g / m ² or more When added, the soft character is lost and cracks occur when bent. For example, when applied to visible light treatment equipment or visible light treatment clothing, the amount of the phosphorescent pigment added must be 300 gZm ^{2 or} more, and sweat absorption, heat retention, and moisture retention are required. For this purpose, if vegetative fiber or synthetic fiber is entangled with a luminous pigment and fixed to form it, even if it is added in an amount of 300 gZm ² or more, cracks will not be caused by bending. This is due to the inherent flexibility of the fibers. Further, by using these fibers, it is possible to form a phosphorescent paper having excellent sweat-absorbing property, heat-retaining property, and mixing property. In addition, in the case of using a soft salted vinyl, a phthalate ester is added as a plasticizer in order to make it soft, and therefore, there is a problem of dioxin and a carcinogenicity when incinerated. In addition, SBR synthetic rubber is Good flexibility but less elastic for the required amount of addition. None of them are excellent in sweat absorption, heat retention, and moisture retention. Since the luminous pigment has coarse particles and high hardness, the luminous paper in the present invention needs to be produced from fibers having high flexibility, such as vegetable fibers or synthetic fibers.

 According to this configuration, as shown in FIG. 1 (B), when ultraviolet light 6 is irradiated from the back surface 5 of the phosphorescent paper 1, the ultraviolet light 6 is irregularly reflected by the irregularly distributed paper fibers of the paper 2, The phosphorescent pigment 3 absorbs the irregularly reflected ultraviolet light 6 and emits visible light 、, and the visible light 7 is irregularly reflected by the irregularly distributed paper fibers of the paper 2 and exits from the surface 8 of the phosphorescent paper 1. After the irradiation of the ultraviolet light 6 is stopped, the afterglow of the phosphorescent pigment 3 is emitted from the surface 8.

 As described above, since the phosphorescent pigment 3 is fixed at a substantially uniform density in the surface direction and the thickness direction of the phosphorescent paper 1, the entire surface of the phosphorescent paper 1 emits light uniformly. Further, since the ultraviolet light 6 irregularly reflected by the paper fibers randomly distributed on the paper 2 irradiates the luminous pigment 3, the ratio of the ultraviolet light 6 absorbed by the luminous pigment 3 increases, so that the luminous efficiency is extremely high. Also, since the visible light 7 is diffusely reflected by the irregularly distributed paper fibers of the paper 2 and exits from the surface 8, the visible light 7 varies depending on the color, thickness, paper clearance, type of phosphorescent pigment 3, and concentration of the paper fibers. Light emission with various unprecedented color sensations can be obtained.

 Next, a photoluminescent paper for phototherapy and printing according to a second embodiment of the present invention will be described. FIG. 2 is a schematic cross-sectional view showing a configuration of a photoluminescent paper for phototherapy and printing according to the present invention. In FIG. 2 (A), a photoluminescent paper 11 for phototherapy and printing has a transparent rayon paper 12 on the surface, and other configurations are the same as those in FIG.

 According to this configuration, since the transparent rayon paper 12 is transparent to ultraviolet light and visible light, if it is irradiated with ultraviolet light, visible light can be emitted with high efficiency as described in FIG. After the UV light irradiation is stopped, the afterglow of the luminous pigment is emitted.

 Further, the photoluminescent paper 11 for phototherapy and printing has high strength because it has the transparent rayon paper 12. .

 FIG. 2 (B) shows an example in which the phosphorescent paper 11 is fixed to the skin of a human body. In the figure, the photoluminescent paper 11 for phototherapy and printing is fixed to the skin 13 of the arm with the transparent rayon paper 12 side up with adhesive tape 14.

As described above, since the transparent rayon paper 12 has high strength, the adhesive tape is stuck, and if it is peeled, it will not be damaged, and the photoluminescent paper 11 for phototherapy and printing should be firmly fixed. Can be used repeatedly. FIG. 2 (C) shows an example in which fluorescent paint consisting of the letters “light” is printed on the phosphorescent paper 11. In the figure, the fluorescent paint 15 is printed on a transparent rayon paper 12. Transparent rayon paper 12 has little bleeding with water and organic solvents, so high-definition printing can be performed, and bleeding of the paint and printing failure do not occur.

 Next, a decorative phosphorescent paper according to a third embodiment of the present invention will be described.

 FIG. 3 is a schematic sectional view showing the structure of the decorative phosphorescent paper of the present invention.

 In FIG. 3 (A), the decorative phosphorescent paper 31 has a transparent acrylic resin layer 32 on its surface, and the other configuration is the same as that of FIG.

 According to this configuration, as shown in FIG. 3 (B), the light emission 7 of the luminous pigment 3 is focused on the transparent acryl resin layer 32.

 Thus, according to the phosphorescent paper for decoration of the present invention, light emission with high uniformity can be obtained over the entire surface of the phosphorescent paper.

 Next, an embodiment of the method for manufacturing phosphorescent paper of the present invention will be described.

 FIG. 4 is a diagram showing an example of an apparatus used for the method for producing phosphorescent paper of the present invention.

 In FIG. 4, 41 is a mixer for mixing the paper fiber and the phosphorescent pigment, 42 is a cylindrical container for putting the mixed solution into the mold container, and 44 is a side wall of the mold container 43. Reference numeral 45 denotes a nonwoven fabric forming the bottom surface of the mold container 43, and reference numeral 46 denotes a stone base on which the mold container 43 is placed. The mold container 43 is formed of a mold frame having a size such as A4 size or B5 size, depending on the size of the phosphorescent paper to be manufactured.

 A method for producing phosphorescent paper will be described using the apparatus shown in FIG. 4 as an example.

 First of all, a thin paper, a luminous pigment, and an aqueous sealer and a laundry paste are added to water, and the mixture is stirred with a mixer 41.

 The thin paper may be either Western paper or Japanese paper. For example, tissue paper such as household tissue paper, kyoka paper, chile paper, toilet paper, etc. may be used, but the thinnest tissue if no particular strength is required. Paper and the like are preferred because they have good light transmission and large light emission. These thin papers are cut short and immersed in water.

Luminescent pigments include zinc sulfide (ZnS), calcium sulfide (CaS), rare earth element-doped strontium aluminate (SrA124: Eu), and rare earth element-doped 'strontium aluminate (Sr4A114: 25: Eu, Dy) or rare earth element-doped calcium aluminate (CaA124: Eu, Nd). Luminescent pigments having a suitable emission wavelength can be selected. These phosphorescent pigments are insoluble in water and organic solvents. Yes, it usually has a particle size of 2.5 μπι or more, and the larger the particle size, the higher the luminous efficiency.However, if the particle size is too large, the dispersion is poor, and the mixture tends to settle during mixing and cannot be used effectively. In the production method of the present invention, it is preferable to use one having a particle size of 10 to 40 / zm.

 Laundry and water-based sealers generate foam that floats on the surface of water with the phosphorescent pigment attached, furthermore, fix the phosphorescent pigment to the paper fibers, bind the paper fibers alternately, and generate bubbles. It is necessary to increase the strength of the foam to the extent that it collapses during the manufacturing process of the present invention. Laundry is starch-based, used for washing at home, cellulose derivative such as CMC (carboxymethyl cellulose), and synthetic based such as PVA c (polyvinyl acetate) and PVA (polyvinyl alcohol). Any of these may be used, but a precipitate is preferred. The water-based sealer may be made of water-based acrylic resin or lacquer, and may be used for waterproofing such as household concrete and mortar.

 Fig. 5 schematically shows the state of the aqueous solution when the aqueous solution was stirred. Fig. 5 (A) shows the state during stirring, and Fig. 5 (B) shows the state after stirring for a certain period of time. This shows the state at the time of performing.

 When stirred by the mixer 41, as shown in FIG. 5 (A), bubbles 51 having the phosphorescent pigment 3 adhered to the surface are generated, and the thin paper is decomposed into paper fibers 52. After agitation for a certain period of time, the mixture is left standing after being agitated for a certain period of time, as shown in Fig. 5 (B). I do. The aqueous solution is separated into a mixed solution 53 in which the foam 51 to which the luminous pigment is attached and the paper fiber 52 are uniformly mixed, and an aqueous solution 54 which does not contain the luminous pigment and the paper fiber. It is preferable to stir the mixer 41 until the paper fiber 52 becomes about 2-3 mm.

When stirring the mixture, the water temperature of the mixture should be in the range of 18 ° C to 22 ° C. The effect of the foam decreases as the water temperature of the mixture drops below 18 ° C. Conversely, the effect of foam becomes too active at temperatures above 22 ° C. When stirred with a mixture without a foaming agent and poured into a container, the finely divided paper fibers and luminous pigment sink to the bottom surface of the container before dehydration, and water remains on the upper surface. The efficiency of dehydration is very poor, and the luminous pigment fixing rate is also very poor. For example, if the mixture is stirred and poured into a container with water at a temperature of 4 ° C, the movement of the gas generated by the aqueous sealer due to the low water temperature reduces the movement of the generated gas, resulting in finer paper fibers and phosphorescent pigments. Gather around the bubbles, hollowing out the interior of the bubbles and causing uneven emission. Conversely, if the mixture is stirred with water at a water temperature of 25 ° C and poured into the container, the gas generated by the foam from the aqueous sealer will be released during the stirring, and the aqueous sealer will be released when poured into the container. As a result, the amount of gas generated by the foam is significantly reduced, and a uniform paper thickness cannot be formed. Also, the fixing rate of the phosphorescent pigment is poor. When the mixture is stirred at a water temperature of 18 to 22 ° C., the gas generating bubbles is moderate, the entanglement of the paper fibers is good, the fixation rate of the luminous pigment is good, and no luminescent spots are generated.

 Next, the mixed solution 53 is transferred to a cylindrical container 42 having a predetermined diameter, and the mixed solution 53 held in the cylindrical container 42 is held vertically in the center of the mold container 43. The mixture 53 is dropped from a predetermined height while controlling the flow rate of the mixture 53. At this time, the cylinder may be quickly pulled upward.

 In this way, since the flow rate of the mixed liquid 53 is controlled and introduced, the bubbles 51 having the phosphorescent pigment adhered to the surface thereof are not destroyed, and the mixed liquid 53 is placed on the bottom of the mold container 43. Enter with uniform thickness.

 In addition, since the bottom surface of the mold container 43 is formed of the nonwoven fabric 45, the dewatering speed can be controlled by the nonwoven fabric 45 having an appropriate gap and thickness. That is, there is no possibility that bubbles are crushed and the luminous pigment is settled while the mixed liquid has a large amount of water.

 In this way, since the dehydration is performed by controlling the dehydration speed, the disappearance time of the bubbles 51 can be adjusted according to the degree of entanglement between the paper fibers 52, and the phosphorescent pigment 3 is uniformly distributed in the surface direction and the film thickness direction of the paper. It is possible to manufacture phosphorescent paper with a fixed distribution.

 For example, as shown in FIGS. 11 (A;), (B) and (C), one side of the mold container 43 is leveled, the other side is lifted and tilted, and the mixture 53 is poured. When the area around the frame 4 4 of the mold container 4 3 is inserted, the mixed solution 53 accumulates on one side (see Fig. 11 (A)), and the mold container 4 3 is quickly returned to its original horizontal position. In this state, the mixed solution 53 accumulated on one side flows to the other side (see Fig. 11 (B)), hits the frame 44 of the mold container 43, and is continuously pushed to the opposite side. By being returned (see Fig. 11 (C)), a paper having a stable thickness can be formed.

 FIG. 6 is a diagram schematically showing a state of a mixed solution put in a mold container.

 FIG. 6 (A) shows a state in which the mixed solution is put into a mold container 43 and dehydrated through a nonwoven fabric 45 for about 60 minutes. Foam with phosphorescent pigment 3 attached 5 1 Paper fiber 5 The figure shows a state in which 2 is mixed.

 FIG. 6 (B) is a view of the state of FIG. 6 (A) as viewed from directly above, and shows that the foam having the phosphorescent pigment 3 attached thereto is uniformly distributed over the entire surface of the mold container 4 3. I have.

FIG. 6 (C) shows the state of the paper 61 in which the dehydration via the nonwoven fabric 45 has been completed and the bubbles 51 have been crushed. Next, drying is performed. Drying is preferably performed in two steps. For the first drying, put the entire mold container 43 into a dryer at 70 to 75 ° C for about 3 hours, and the water content will be 40 to 50%. There is no state. In this case, care must be taken if drying is performed continuously in an atmosphere with a humidity of 90% or more at a temperature of 85 ° C or more for 15 minutes or more, since the light-emitting function of the phosphorescent pigment may be lost. . Next, lightly press with a roller to immerse the crushed traces of foam formed on the phosphorescent paper, and then dry to a moisture content of about 5% by the second drying. Then, apply the roller again to finish the surface of the paper evenly.

 Fig. 7 schematically shows the appearance of the finished phosphorescent paper.

 FIG. 7 (A) is a plan view, and FIG. 7 (B) is a cross-sectional view.

 In the figure, black portions 71 indicate paper, and white portions 72 indicate voids formed by bubbles. As shown in FIGS. 7 (A) and (B), the phosphorescent paper produced by the production method of the present invention has voids 72 caused by bubbles.

 Next, examples of the present invention will be described.

 (Example 1)

 350 cc water, 3 sets of paper tissue finely cut with scissors (6 pieces) 'about 2.5 g, transparent water-based sealer (manufactured by Kanhe Papio Co., Ltd.) 9 cc, laundry paste [Sanwa Yushi Kogyo Co., Ltd. 7 cc) was put into a mixer, and 4 g of a luminous pigment (manufactured by Nemoto Special Chemical Co., Ltd., trade name: N night light) was added while rotating the mixer, and mixed well.

 If the mixer stops rotating and left for 5 to 10 minutes, the aqueous solution separates into upper and lower layers, and the mixed liquid layer containing the upper layer of paper fiber and foam becomes 30%, and the lower layer aqueous solution part becomes 70%. There was less than 5% of the phosphorescent pigment remaining in the lower aqueous solution, and most of the phosphorescent pigment was contained in the upper foam part.

 A nonwoven fabric is placed on a stone base (30 mm square, 10 mm thick), and a stone frame (external size of 300 mm square, 20 mm thick) is placed on top of it. A cylinder having an inner diameter of 8 O mm into which the above mixed solution is poured is set up, and this cylinder is immediately lifted at once and spread in a mold container. The mixture is slowly dewatered through the bottom nonwoven fabric.

When the water does not drip, place the stone frame on the stone bed and place it in a dryer to dry at about 60 ° C for 20 minutes. Both the stone bed and the stone frame have good heat conduction and promote drying. After drying, the paper braid becomes swollen and swelled, and the paper surface becomes firm enough to be pushed off by a blade. If the water content of the phosphorescent paper on which the green color phosphorescent pigment (SRA124: EU) has been fixed is 15% or more, drying at 85 ° C or more for 15 minutes or more will enhance the light-emitting function. Fear of losing You need to be careful.

 Next, it is taken out of the dryer with a water content of about 30 to 50% and lightly pressed with a roller. After drying, the phosphorescent paper was removed from the crushed stone by iron pressing. This phosphorescent paper had no pinholes and the phosphorescent pigment was not unevenly distributed. Similar results were obtained when 8 g of the phosphorescent pigment was added instead of 4 g.

 The phosphorescent paper thus obtained can emit blue or green uniform light. Also, when two cylinders are set up in a mold container and a mixture of luminous pigments is poured into each cylinder and lifted at the same time, half of the luminous paper is blue and the other half is green. A phosphorescent paper having excellent properties can be obtained.

 When phosphorescent pigments with emission colors of red, orange, and pearl were used, phosphorescent paper having uniform red, orange, and pearl emission was obtained in the same manner.

 (Comparative Example 1)

 The same thin paper, water-based sealer, laundry paste and luminous pigment as in Example 1 were placed in a water tank, and production of luminous paper was attempted by a conventional hand-making method. The moment the paper was taken out of the tank after hand-making, more than 80% of the luminous pigment flowed down, and the luminous intensity of the luminous paper dropped significantly.

 (Comparative Example 2)

 Production was performed under the same conditions as in Example 1 except that the mixture was slowly poured into a mold container without using a cylinder. The resulting phosphorescent paper had variations in the thickness of the paper, and uneven light emission resulted in a phosphorescent paper with uneven surface light. Similar results were obtained when the injection was performed several times. In these cases, it is considered that the foams collide with each other several times and the size of the foams is not uniform, and the paper fibers are unevenly distributed.

 (Comparative Example 3)

 A phosphorescent paper was manufactured under the same conditions as in Example 1 except that no aqueous sealer was added. Separation of the aqueous solution after stirring with a mixer revealed that the mixed liquid layer was 75% and the lower aqueous solution portion was 25%, but more than 50% of the phosphorescent pigment was precipitated in the lower aqueous solution. . The phosphorescent pigment attached to the surface of the resulting phosphorescent paper was scattered like dust when it was wiped, and the luminous intensity was reduced and luminous unevenness occurred. This is considered to be due to the fact that the absence of the aqueous syrup reduces the strength of the foam and makes it impossible to retain the phosphorescent pigment.

(Example 2) 450 cc of water, 3 sets of paper tissue finely cut with scissors (6 pieces) Approx. 2.5 g, transparent water-based sealer (manufactured by Kanpe Papio Co., Ltd.) 11 cc, laundry paste Glue] 9 cc, strontium aluminate luminous pigment [SrA1204: E, Dy green luminescent color Nemoto Special Chemicals Co., Ltd.] 2 g, water-based fluorescent paint red [Asahijin Co., Ltd.] 3. 3 g was mixed well in a mixer and allowed to stand for 5 minutes.The aqueous solution was a mixture of the foam containing the phosphorescent pigment and paper, the upper layer mixture of fibers, the foam containing the phosphorescent pigment, and the paper fibers. It was separated into two lower layers that did not contain.

 A non-woven fabric is placed on an aluminum plate (30 OmmX 40 Omm, 15 mm thick) with a panel heater attached to the back, and a mirror stainless steel frame (215 mmX 315 mm, 15 mm thick) is placed on top of the nonwoven fabric. The mixture was injected into the center of the inside. After dehydration through the nonwoven fabric 12, the aluminum plate was heated by a panel heater at 60 to 80 ° C for 15 minutes, and simultaneously dried by blowing hot air of 50 ° C or higher while moving. After the formed paper was dried to a moisture content of about 20%, the surface of the paper was pressed with a roller. After the paper was dried to a moisture content of about 5%, it was pressed at 100 ° C to eliminate any irregularities on the paper surface.

 Luminescent paper with a size of 215 X 315 mm and a thickness of 0.3 mm is obtained. This phosphorescent paper has a high afterglow intensity, a long afterglow time, a luminous color of luminous pigment, and a luminescent color of fluorescent paint. It also emits a different color, emits confidential light with a brownish glassy glow in the dark, and obtains an extremely beautiful phosphorescent paper. In addition, in addition to the examples shown here, red, orange, yellow, dark green, light green, pink, dark blue, pin Light-emitting paper of various colors such as cupard can be obtained.

 (Example 3)

 A phosphorescent paper was manufactured in the same manner as in Example 2 except that a phosphorescent pigment [manufactured by Nemoto Specialty Chemical Co., Ltd., trade name: N night light] was used in place of the aqueous fluorescent paint. This phosphorescent paper provided a delicate feel in the dark, unevenness, and uniform light emission.

 Next, an embodiment of the photoluminescent paper for phototherapy and printing according to the present invention will be described.

 The method for producing a photoluminescent paper for phototherapy and printing according to the present invention is different from the above-mentioned production of the phosphorescent paper only in that a transparent rayon paper is laid on a non-woven fabric and a mixed solution is introduced.

According to this method, phototherapy and printing phosphorescent paper having transparent rayon paper on the surface can be manufactured. Next, examples will be described.

 (Example 4)

 Water 500 cc, 3 sets of paper tissue finely cut with scissors (6 pieces) Approx. 2.5 g, transparent water-based sealer (manufactured by Kanpe Papio Co., Ltd.) 12.5 cc laundry paste (manufactured by Kao Corporation, white Emulsion] 10 cc, luminous pigment (N Nekko, manufactured by Nemoto Special Chemical Co., Ltd.) 4 g was stirred with a mixer for 1-2 minutes. When the mixer is stopped and left for 5 to 10 minutes, the aqueous solution separates into upper and lower layers, and the mixed layer of paper fiber and foam in the upper layer is 30%, and the aqueous layer in the lower layer is 70%. However, the phosphorescent pigment remaining in the aqueous solution is less than 5%, and most of the phosphorescent pigment is contained in the upper mixed liquid layer. Since the lower part of the aqueous solution is highly transparent, it can be seen that the laundry is almost completely contained in the upper part of the aqueous solution.

 Nonwoven fabric is laid on a stone stand (400 mm x 300 mm, 10 mm thick), and Daiwa Rayon paper (made by Daiwa Co., Ltd.) is laid on it, and a stone frame (400 mm) is further laid on it. X 30 O mm, internal dimensions 3 15 X 2 15 mm, 10 mm thick), put a cylinder with an inner diameter of 8 O mm at the center of the mold container, and inject the above mixture Immediately lift the cylinder at once and put it in a uniform thickness in a mold container. The mixture is slowly dewatered through the bottom nonwoven.

 When the water did not drip, the stone frame was placed on the stone bed and placed in a dryer and dried at about 70-75 ° C for 3 hours. Both the stone bed and the stone frame have good heat conduction and promote drying.

 After drying, the paper braid is in a state of being fluffy and JI Peng, and the paper is hard enough to be pushed out by a blade.

 Remove the phosphorescent paper with a water content of about 40 to 50% from the dryer and press the phosphorescent paper lightly with rollers to immerse the holes created by the bubbles. The non-woven fabric was removed so that the rayon paper did not peel off, dried for another 2 hours, and pressed with a roller to manufacture photoluminescent paper for phototherapy and printing.

 Next, an embodiment of a method for producing a decorative phosphorescent paper according to the present invention will be described.

 According to the method for manufacturing a phosphorescent paper for decoration of the present invention, a transparent ataryl resin is rubbed into the surface of the phosphorescent paper manufactured by the above-described manufacturing method. For example, printing may be performed with a roller to which a transparent ataryl resin is attached.

 One side of the transparent acryl resin layer formed by rubbing becomes an uneven surface because the transparent ataryl resin enters the voids of the paper braid, and the other side becomes flat. Therefore, the luminescence from the luminous pigment diffusely reflected and diffused is condensed, and a highly uniform surface luminescence is obtained.

Next, an embodiment of the light emitting method using the phosphorescent paper of the present invention will be described. The luminous efficiency of rare earth element-doped strontium aluminate and rare earth element-doped 'calcium aluminate-based luminous pigments in UV light excitation increases as the temperature of the luminous paper increases. For example, when the same ultraviolet fluorescent lamp (commonly known as black light, 20 lit, wavelength of 320 to 380 nm) is illuminated on the back surface of the luminous paper, the luminous efficiency when the luminous intensity is 15 ° C is 100. As a percentage, the luminous intensity increases by about 2% for a 1 ° C rise, 65. In C, it reached about 200%. The brightness at this time is such that light emission can be easily confirmed even under sunlight.

 Therefore, it is preferable to use the phosphorescent paper at the highest possible temperature.However, since the phosphorescent pigment is easily deteriorated, it is desirable to keep it at a high temperature of 100 ° C or less when a long life is required. .

 Next, an embodiment of a method of applying a fluorescent paint to the phosphorescent paper of the present invention and causing the fluorescent paint to emit light by emission of the phosphorescent paper or by afterglow of the phosphorescent paper will be described. FIG. 8 is a diagram schematically showing a principle of causing a fluorescent paint to emit light by light emission or afterglow of the phosphorescent paper.

 In FIG. 8, reference numeral 81 denotes a fluorescent paint applied to the surface of the phosphorescent paper 1, and reference numeral 82 denotes fluorescent light emitted from the fluorescent paint.

 The phosphorescent material of the phosphorescent paper 1 absorbs the ultraviolet light 6 emitted from the back side of the phosphorescent paper 1 and emits visible light 7. The fluorescent paint 81 absorbs the light emission 7 and emits its own fluorescence 82. Further, if the phosphorescent paper 1 is stored with the ultraviolet light 6, the fluorescent paint 81 absorbs the afterglow of the phosphorescent paper 1 and emits the fluorescent light 82 even after the irradiation of the ultraviolet light is stopped.

 The fluorescent paint 81 can be used as long as it can emit light of the phosphorescent pigment as excitation light. Rare earth element-doped strontium aluminate-based luminous pigments emit blue (peak wavelength 490 ηηα earth 50 nm) or green (peak wavelength 520 nm, 50 nm), and emit this light. For wavelengths, almost all phosphors emit fluorescence. Next, an embodiment of the phototherapy method using the phosphorescent paper of the present invention will be described.

 The phosphorescent paper for phototherapy uses a rare earth element-doped strontium aluminate phosphorescent pigment as the phosphorescent pigment and emits light in blue (peak wavelength 490 nm ± 50 nm) or green (peak wavelength 520 nm ± 50 nm). is there.

 This phosphorescent pigment contains no radioactivity and no harmful components harmful to the human body (see Tokyo Metropolitan Isotope Research Institute, transcript, 7a Lab. No. 0159), (Japan Food Analysis Center , Analytical Test Report, No. 599080257-003).

In addition, according to animal experiments, the skin is corrosive, irritating, sensitizing, acute (subacute) toxic, chronic It is negative for toxicity, carcinogen, metamorphosis, reproductive toxicity, teratogenicity, etc., and has extremely low impact on the environment. After use, it can be treated as general waste. Further, since the skin contact surface is paper, it is excellent in heat retention and moisture absorption, and also excellent in wearing feeling. In addition, since it has strong transparent rayon paper, it can be easily adhered to the skin with medical adhesive tape or the like, and it can be easily attached and detached.

 The phototherapy phosphorescent paper is used in close contact with the affected area with a medical adhesive tape or the like. In sunlight, the luminous pigment of the phototherapy luminous paper absorbs the ultraviolet rays of the sunlight and converts it into light of a predetermined wavelength to irradiate the affected part. Under a fluorescent light, the luminous pigment of the phototherapy luminous paper absorbs the ultraviolet light of the fluorescent light, converts it into light of a predetermined wavelength, and irradiates the affected part. In the absence of light, such as when sleeping, the luminous pigment of the phototherapy luminous paper irradiates the affected part with afterglow.

 The wavelength at which the visible light emitted by the phosphorescent paper reaches the depth of the dermis is 420 to 600 nm, and if it is 420 nm or less, pigmentation may occur. In addition, in DNA damaged by ultraviolet light, two adjacent pyrimidine bases on the same chain take a cyclobutane structure to form a dimer (pyridimine timer). Therefore, the three-dimensional structure of the DNA is distorted and the function of the DNA is hindered. This dimer is activated by visible light of 300 to 600 nm and is cleaved by the action of a light-recovering enzyme, returning to the original structure of the two pyrimidine bases. This phenomenon is called light recovery. This enzyme is widely distributed in bacteria, yeast, molds, plants, animals and lower marsupials, leukocytes (humans, magpies), bone marrow, and so on. [See, for example, Nanzan Medical Encyclopedia, second edition, published on January 30, 1990, page 1723]. In addition, it can be easily tested whether the light emission of the phosphorescent paper is transmitted to the dermis. By irradiating the phosphorescent paper (mixing amount of phosphorescent pigment 8.0 g) with ultraviolet light and saturating it and applying it to the back of the ear in the dark, it is easy to see that light emission is transmitted from the back to the front. .

 By applying heat energy (heating) to the afterglow brightness of the phosphorescent paper, the afterglow brightness can be increased and the skin can be irradiated with afterglow. For example, as a property of the phosphorescent pigment added to the phosphorescent paper, light emission is released by thermal energy. If the afterglow luminance is 100% at normal temperature of 15 ° C, it will increase by about 2 ° C per 1 ° C. % The afterglow brightness increases. When this phosphorescent paper is fixed to the skin, the body temperature conducts heat, the afterglow brightness increases by about 43%, and the permeability to the dermis becomes higher.

Alternatively, a white cloth may be adhered to the phosphorescent paper, and the afterglow luminance may be reflected to irradiate the skin with the white cloth. For example, if the white color of the background color is 100%, the effect of the background color on the afterglow luminance is 81% for silver, 62% for yellow, 52% for green, 41% for blue, 31% for red, and 31% for black. Two 8%.

 In this way, by using the phototherapy method using the phosphorescent paper for phototherapy of the present invention, phototherapy can be performed regardless of location and time and while working.

 In addition, since the emission wavelength can be selected by selecting the type of the phosphorescent pigment, various light treatments suitable for the purpose of treatment can be performed. Phototherapy may be performed by irradiating the photoluminescent paper with ultraviolet light such as black light.

 Hereinafter, a demonstration example obtained by the phototherapy method using the phototherapy phosphorescent paper will be described. <Example 1 of atopic dermatitis>

Symptoms of atopic dermatitis are about 100 days, steroids are used for 7 days, and symptoms occur on the torso.At bedtime, there is itching that makes it impossible to sleep.

<Example 5 of demonstration of atopic dermatitis> Atopic dermatitis has a symptom period of about 2 years and steroid use (3-4) for about 4 months.Symptoms appear on the back of the hand, itching of the skin, dullness, roughness, A partly cracked black discolored woman (23 years old) tried it. The mixed-condition of the phosphorescent paper, to 0. 069m ^3, water 500 cc: Aqueous Sealer 9. 38 cc: Glue one 4. 67 cc: phosphorescent顏料one _{S r 4 A 1 14 0 25} 4. 0 g: We decided to mix three sets of paper tissue. The method of use was to discontinue the use of steroids and fixed them to the affected area at bedtime before use. The implementation period and the improvement evaluation method are the same as in Demonstration Example 1. as a result,

 A. Skin itch was evaluated as ③ four weeks after use.

 B. The evaluation of (3) was obtained after 6 weeks from the use of the skin gloss.

 C. Skin roughness was evaluated in (3) 6 weeks after use.

 D. Skin discoloration was rated 4 weeks after 4 weeks.

 The results obtained in these demonstration examples 1 to 5 of atopic dermatitis are as follows. [Comparison between demonstration examples 1 and 2]

The duration of symptoms in Demonstration Example 1 is considerably shorter than in Demonstration Example 2. They use steroids for a short period of seven days. In addition, three items were completely cured, and one item showed good results. In Demonstration Example 1, a mixed condition of the phosphorescent paper, to 0. 0 69 m ^3, the water 500 cc: Aqueous Sealer 9. 38 cc: Glue one 4. 67 cc:蓄light pigment one S r A l ₂ C 8 0.0 g: A mixture of three sets of paper tissues (hereinafter referred to as “Level 2”) was used. On the other hand, in the illustrative example 2, as a mixing condition of the phosphorescent paper, to 0. 069m ^3, water 500 cc: aqueous shea one error 9. 38 cc: Glue one 4. 67 cc: phosphorescent pigment -S r A 1 ₂ 0 ₄ 4. 0 g: a mixture of paper tissue three sets (hereinafter, "level 1" will leave) was used. In other words, there is a difference in the level of phosphorescent paper. In other words, if steroids are used even for a short period of time, a high level of phosphorescent paper is required.

 [Comparison between demonstration examples 2 and 5]

Despite the allergen factors and age, the duration of symptoms is the same. The difference is in the power of using steroids in the past. The level of phosphorescent paper is both level 1, but the practitioner's self-evaluation is completely different. We see how this is due to the side effects of steroids. If steroids have not been used in the past, at level 1, three out of four improvement results were completely cured, and the remaining one showed good results. [Comparison with demonstration examples 3 and 4]

 Demonstration Example 4 has 3.5 times the symptom duration and 9 times as long as the steroid use period, compared to Demonstration Example 3. As a patient with atopic dermatitis, it seems to be severe. In the implementation method, demonstration example 4 used level 2 while using steroids every day. In demonstration example 3, steroids were stopped and level 1 was used. 4 Self-evaluation at weekly intervals for 2 days of use. The main role of steroid-based drugs is to eliminate itch quickly and quickly, but it is a temporary deception, steroid dependence, and skin becomes chronic. Will be. When very strong steroids (3 to 5) are used for a long period of time, as in Demonstration Example 4, it appears that the skin has become considerably more chronic. However, the improvement result of Demonstration Example 4 is the discovery of a notable fact. That is, the use of steroids has improved skin condition. This means that new treatment methods using phosphorescent paper and steroids are quite possible.

Demonstration example of facial skin care>

 A total of eight practitioners, one in their 60s, five in their 40s, and two in their thirties, used a phosphorescent paper as a facial mask at bedtime for 28 days and fixed with rubber bands. Use. The phosphorescent paper used was the “Level 1” mentioned above. The target items for improvement are as follows.

 1. Improvement of skin beam

 2. Improvement of skin gloss

 3. Improvement of makeup paste

 4. Improvement of rough skin

 5. Improvement of fine lines

 6. Improvement of spots and freckles

 The improvement evaluation method was a five-step self-evaluation by the implementer, and the items were divided into (1) no improvement, (2) slightly improved, (3) improved, (4) improved, and (4) greatly improved. The results are as follows.

 ②Three people who improved slightly (37.5%)

 ③Improved 1 person (12.5%)

 ④ 0 people (0%) who improved well

Above, when the improvement results of all six items are divided by%, ① No improvement (25%)

 ② Slightly improved (33.3%)

 ③ Improved (8.3%)

 よ く Improved (20.8%)

 ⑤ Greatly improved (12.5%)

Becomes The self-evaluation of individual items is as follows: For items such as skin gloss, degree of application of makeup, and rough skin, those who rated the improvement effect as ④ or で are rated as high as 50%. As for the fine wrinkle improvement results, the sum of ②, ③ and ④ is 62.5%, which is more than expected. Judging from this fact, it means that the skin damage caused by the ultraviolet rays of sunlight is repaired. By increasing the level of phosphorescent paper, a further improvement effect can be brought about. <Demonstration examples of morbidity>

 Symptoms of sprouts are more than 10 years. Every year, from late January to early February. Always apply to women (61 years old) who suffers from bruising on their toes, itching in winter, and the condition continues until early spring. I was asked to. The phosphorescent paper used was the "Level 1" described above. The method of implementation was to calculate the time of the occurrence of morbidity and back to the seedlings, and fixed to the affected area at bedtime before use. During the implementation period, the improvement evaluation method is the same as the evaluation method of the demonstration example of facial skin care. As a result, after the 42-day implementation, the burnt symptoms that had occurred every year disappeared, and the evaluation was (1) greatly improved. After the completion of the study, they were fixed to the affected area two or three times a week. This example demonstrates that the wavelength and the heat retention of the phosphorescent paper promoted blood circulation in the affected area. In addition, further improvement can be expected by increasing the luminous power.

<Eyebrow hair growth demonstration example>

A 52-year-old man was asked to fix it on his eyebrows at bedtime. The mixing conditions of the phosphorescent paper, to 0. 06 9m ^3, water 500 cc: Aqueous Sealer 9. 38 cc: Glue one 4. 67 cc: phosphorescent pigment _{_S r A 1 2 0 4 16.} 0 g: Paper tissue A mixture of three sets (hereinafter referred to as “Level 3”) was used. During the implementation period, the improvement evaluation method is the same as the evaluation method of the demonstration example of facial skin care. As a result, the evaluation result was ④ well improved after 42 days of implementation. After the 42-day run, the results were noticeable to third parties, who noticed that their eyebrows were darkening.
