Description
. - 1 -INDICATION ELEMENT WITH PROTECTIVE LAYER
AND PROCESS FOR PRODUCING THE SAME
BACKGROUND OF TH~ IN~ENTION
The present invention relates to an indication element with a protective layer and a process for ; producing the same.
. . .
~; 5 There are many kinds of indication elements for -` use in sheet-like articles with a back number and other informations which are attached to the breast or back of a wear of a player in a variety of sports competitions;
name cards or tags, and nameplates or doorplates for identification of a private person or a variety of bodies such as school, company and government office; boards indicating schedules of train, streetcarl bus or the , like; a variety of information boards indicating name of ~' station, etc; boards indicating name of town or street number; and a variety of indoor or outdoor signboards.
In the case of these indication elements, the i format for a kind of indication element is unified but many kinds of products which have different indication contents with each other must be produced for every kind of indication element. For this reason, heretofore, the ~, -:.
'~ production of such indication elements was a typical case of a multikind and small-quantity production.
~(~ Accordingly, the indication elements were generally produced by hand. However, there has been a demand for automatization of the production thereof to !~ accommodate a rise in price due to a rise in labor cost and a need for shortening of a period from ordering to delivery.
' An attempt to use as an indication element a label or paper sheet on which print images were produced ~ by means of a computer or word processor was made.
i' However, any indication element of good quality was not obtained.
One of the reasons therefor is as follows: In ~ 35 the case of a conventional handwritten indication :~, ., , ~r . .: - .
1.~' : ' ', .,.' ~'..
element, an image was drew on a resin sheet by using a paint having good weatherability and abrasion resistance. However, in the case of utilizing a computer for producing print images, an ink which gave a print image having a fastness comparable to that obtained by using the conventional paint and also had a property of forming a print image on a resin sheet was unavailable.
In order to supply the poor fastness of the print image of the ink, the present inventor made an attempt that a resin ~ilm was laminated to the surface of a resin sheet on which a print image was previously formed. However, the ink of the print image was flowed by the heat and pressure during the lamination, whereby the print image was deformed so that the resulting article did not effect a function as an indication -1 element.
, As a result of the trial and error mentioned above, the present inventor has developed an indication element which has a clear image, although the element is ~i 20 produced by utili~ing a lamination technique.
:, SUMMARY OF TH~ INVENTION
The present invention provides an indication element with a protective layer which comprises a receiving medium having an image in a desired pattern on one side thereof, said image being formed by transferring a transferable colored ink of a thermal transfer ink sheet to said receiving medium; and a laminating material ~l laminated to the image-bearing side of said receiving ~ 30 medium, at least the surface layer of said receiving ; medium on the image-bearing side or a~ least the surface layer of said laminating material on the side in contact with said receiving medium being compatible with the vehicle of said transferable colored ink.

DETAILED DESCRIPTION
In accordance with the present invention, an image of the transferable colored ink transferred to the receiving medium is united either to the receiving medium in the case of using the receiving medium with the surface layer compatible with the transferable colored ink or to the laminating material in the case of using the laminating matsrial with the surface layer compatible with the transferable colored ink. The uniting is effected by application of heat and pressure during the lamination step. The image once united to the receiving medium or laminating material does not flow when it is further heated at a high temperature higher than the melting temperature of the ink during the lamination step and maintains substantially the same clear shape as that of the original image formed on ths receiving medium.
, Thus the present invention provides an indication element with a protective layer having a clear image.
Further, in accordance with the process of the present invention wherein an image is formed by a thermal transfer printing method using a thermal printer, a clear print image can be formed readily. Moreover, since an ` information processing function of a computer or the like i can be directly used in the thermal transfer printing !;.,~ 25 methodJ the production of this kind of indication element, the automatization of which was heretofore difficult due to multikind and small-quantity production, can be automatized. Accordingly, an indication element having a beautiful image comparable to that handwritten by a skilled craftsman can be obtained in a high .> productivity.
Hereinafter, the term "sheet" is intended to be a concept including a film, unless otherwise noted.
-~ According to an embodiment of the present , 35 invention, an image receiving medium wherein at least a surface layer thereof is compatible with the vehicle of a transferable colored ink used for forming an image thereon is used.

The embodiment will be explained hereinafter.
At least the surface layer of the receiving medium is composed of a thermoplastic resin compatible - with the vehicle of the transferable colored ink. It is preferable that the thermoplastic resin constituting the : surface layer has a softening temperature lower than the heating temperature in the lamination step. The uniting of an image to the surface layer of the receiving medium is more readily and completely effected, because the surface layer is softened during the larnination step.
Examples of the resin used in the receiving medium include polyamide resins preferably having a softening temperature of about 50C to about 120C;
polyurethane resins; polyester resins preferably having a 15 molecular weight of about 2 x 104 to about 3 x 10~;
ethylene-vinyl acetate copolymer resins preferably having a softening temperature of about 50C to about 90~C, butyral resins such as polyvinyl butyral, vinyl chloride-vinyl acetate copolymer resins, low desity polyethylenes, -~ 20 syndiotactic-1, 2-polybutadiene preferably having a melting temperature of about 75C to about 90C, styrene-. . .
butadiene copolymers, vinyl chloride resins, chlorinated polyethylene resins, an~ polypropylene resins.
' These resins may be used singly or as admixtures of two or more kinds thereof. Other resin or additive may be added to the above-mentioned specific resin used as a main component.
The image receiving medium used in the present ~. , . invention may be a sheet formed from the above-specified ` 30 resin per se. Alternately a sheet formed by applying the above-specified resin to another sheet material such as cloth, paper or sheet of other resin in a desired coating thickness also may be used. A thickness of 10 to 100 ~m is sufficient for the thickness of the sheet of the ~^ 35 specific resin or the coating of the specific resin.
- An adhesive may be applied to the opposite side of the receiving medium so as to bond the receiving medium to another article. Instead of the application of li .. .
. -,,~
~32398~
the adhesive, the receiving medium per se may be composed of a heat-weldable resin which may be selec~ed from the above specific resins.
A ~hin flexible sheet is used as the receiving ; 5 medium to form an image by means of a thermal printer.
If there is a possibility that, when the receiving medium is mounted in a printer, the receiving medium winds round a platen in the case that the back surface of the receiving medium possesses a heat-~eldability to the platen or has an adhesive layer, orthe receiving medium per se is too soft, a pasteboard such as release paper may be removably attached to the -~ back surface of the receiving mediumO
Any conventional thermal transfer ink sheet can be used as the thermal transfer ink sheet without particular limitation. For example, a thermal transfer ~` ink sheet wherein a heat-sensitive transfer ink layer is provided on a support including thin high density papers such as condenser paper and glassine paper, and resin films such as polyester film, polyethylene film and polycarbonate film can be suitably used.
The ink layer may be provided on the support by means of a conventional hot-melt coating or solvent coating using water or organic solvent as a solvent.
If necessary, a conventional sticking-~' preventive layer such as a silicone resin layer may be provided on the back surface of the support.
. As the heat-sensitive transfer ink layer, there .
. can be used either one-time type ink layer wherein the whole ink of selectively heated portion of the ink layer is completely transferred by one-time use, or a multi-use ; type ink layer wherein the ink of selectively heated ~ portion of the ink layer is not completely transferred by - one-time use and the same portion of the ink layer can be used plural times for transfer printing. However, the colored ink of the heat-sensitive transfer ink layer -- which is melt-transferred to the receiving medium must !`~ contain as a main component of the vehicle a resin :...
`
',~
;~: ~t , , , - , . .. .
~L3~39~2 .
compatible with the resin constituting at least the surface layer of the receiving madium.
It is preferable to use, as the compatible resin component in the colored ink, the same kind of the resin as the above-mentioned resin of the surface layer of the receiving medium used. However, a resin which is different in kind from but has substantially the same solubility parameter as the resin of the surface layer of the receiving medium can be used. Preferably the ; 10 compatible resin component is used in a proportion of ` about 3~20 by weight or more of the total amount of the vehicle of the transferable colored ink~
Some combinations of resins which are different in kind from each other but are compatible with each other are shown in Table 1. In Table 1, the item "Compatible resin component of ink vehicle" in the right column means a resin component which is contained in a vehicle of 2 transferable colored ink and which is ; compatible with the resin of a receiving medium described in the left column. With respect to each combination shown in Table 1, plural kinds of resins exemplified as the compatible resin component in the ink vehicle for a kind of resin of the receiving medium may be used singly or as admixtures of two or more kinds thereof. An incompatible resin may be used in combination with the above compatible resin component as a vehicle component with limits not to injure the purpose of the present ; invention.

These auxiliary vehicle components are selected such that the miscibility or compatibility with the above-mentioned compatible resin component, and the characteristic properties of the ink such as viscosity and melting temperature are adjusted to secure the clearness of an image. Any usual - dye or pigment can be used as a coloring agent.
Preferably the viscosity of the transferable ~ colored ink is not lower than about 2 poises at 100C.
;~ In the case of the one-time type heat-sensitive transfer ink layer, two or multi-layered structure can be ; adopted other than one-layered structure. For example, `~- 35 when the releasability of the colored ink layer from the support in transfer operation is poor, a layer composed of a wax which is reduced significantly in its viscosity when it is heated in transfer operation may be provided ", .

Further, another transferable layer containing no coloring agent may be provided on the surface of the colored ink layer to prevent an accidental ~` transferring of the colored ink to the receiving medium.
In the case of the multi-use type heat-sensitive transfer ink layer, any conventional ink layer may be used. In particular, an ink layer wherein a ' transferable colored ink is contained in an `; untransferable resinous sponge layer is preferably used.
i As the laminating material, there can be used any sheet capable of being bonded to the image-bearing surface of the receiving medium when the laminating material is pressed under heating to the receiving medium in the lamination step. The laminating material per se need not have a heat-weldability, if the receiving medium has a heat-weldability to the laminating material.
~ 20 Examples of the laminating material include films or :~ sheets of rigid polyvinyl chloride, soft polyvinyl ~i chloride, polycarbonate, polyester, acrylic resin, ., tetra~luoroethylene copolymer and difluoroethylene copolymer.
The laminating material may be a single-layered -~ sheet or a multi-layered sheet. An example of the multi-layered sheet is a sheet consisting of an acrylic resin layer, a tetrafluoroethylene copolymer layer provided on one surface of the acrylic resin layer and a soft~or hard . , vinyl chloride resin layer on the other surface of the acrylic resin layer. The thickness of the laminating material is usually from 3 to 800 ~m.
It is enough to practice the present invention if at least one of the laminating material and the '~ 35 receiving medium is transparent. Usually, howsver, a ~ transparent laminating material is used and the view from ''~ k' the laminating material embraces the image of the ~, indication element.

When a transparent laminating materLal is used, a right-reading image can be formed on the receiving medium.
A transparent image receiving medium may be used so that the view from the receiving medium embraces the image of the indication element. In that case, mirror reverse images are formed on the receiving medium.
A weatherability of the indication element can be improved by incorporating an ultraviolet absorber or analogous additive into at least one or all of the - laminating material, the receiving medium and a foundation mentioned below.
Some embodiments of the process for producing ; the indication element of the present invention will be explained by referring to the drawings.
.~ First Process (Fig. 1) , Signals corresponding to a pattern processed by a computer 1 such as personal computer are input into a heat-sensitive transfer printer 2, wherein an image corresponding to the pattern is printed on a receiving medium A by using the thermal transfer ink sheet B.
The receiving medium A on which the print image is formed i9 fed together with a transparent laminating ; material C into a laminator 3, wherein the lamination i~
: ,~
~ 25 carried out at a temperature hi~her than the softening :~ temperature of the thermoplastic resin constituting the receiving medium to give an indication element D.
Usually the heating temperature for the lamination is from 70 to 150C.
After the lamination step, if necessary, the 'r ndication element 3 may be bonded to a foundation E on ~; the side of the receiving medium A. If the receiving ` medium A has a heat~weldability to the foundation E, the :~ indication element D can be welded to the foundation E on .,s the side of the receiving medium A by means of a hot press machine 4.
~ Any suitable article can be used as the ,~ foundation E depending upon the use of the indication . .

, . . .
~323~82 element D. Examples of` the foundation E include plates or sheets of materials such as metal, synthetic re~in or wood and fabrics of natural or synthetic fiber.
Further, in the lamination step, the lamination and the bonding to the foundation may be effected simultaneously by putting the laminating material C on the ~ront surface of the receiving medium A while putting the foundation E on the back surface of the receiving medium A, and applying a pressure to the assembly under heating.
Moreover, in the case of an indication element D wherein a transparent receiving medium A is used and a mirror reverse image is formed on the transparent receiving medium A and a laminating material C which may be opaque is laminated to the receiving medium A, the ~ foundation E is bonded to the indication element D on the - side of the laminating material C.
Second_process (Fig. 2) - It is possible to ~orm an image on the receiving medium by utilizing a hot ray instead of a printer.
According to this process J an original F having an image formed by using a substance having a radiation absorbing property such as carbon black is prepared. The original F is placed on the back surface of thermal transfer ink sheet B which is placed on the receiving medium on the side of the ink layer. If a thin receiving medium is used, the original F can be placed on the back ~ surface of the receiving medium. The assembly is - 30 irradiated with a hot ray such as infrared ray, whereby "'J portions of the ink layer corresponding to the image of the original F are molten and transferred to the receiving medium. Subsequent procedures are the same as those of the first process mentioned above.
When the second process is adopted, there can be used an image receiving medium which is previously bonded to a foundation, or a material which is hard at ordinary temperatures, a thick sheet or plate material or . .

~ 3~3982 a thick cloth as the image receiving medium.
In the case of these receiving media which are used with difficulty in a usual printer, an image can be formed thereon by using a small-sized printer which can ; 5 be moved manually or automatically on a desk.
According to the present invention, a laminating sheet C is placed on a receiving medium A
having an ink im~ge I formed by transfer as shown in Fig 3 and laminated thereto, whereby the ink ima~e I is united to the thermoplastic resin of the surface layer of the receiving medium A by the action of heat and pressure during the lamination to give an integrated ink image I' as shown in Fig. 4.
The reasons therefor are that the`vehicle of the colored ink contains a resin component which is compatible with at least the surface layer of the receiving medium A and that the thermoplastic resin of the surface layer of the receiving medium A has preferably a softening temperature lower than the laminating temperature. Accordingly, the flowing of the ink image I formed on the receiving medium A which has `~ been encountered with the conventional method is prevented to give an indication element having a clear image.
According to another embodiment of the present invention, a laminating material wherein at least the ;
surface layer thereof on the side in contact with the receiving medium is compatible with the vehicle of a transferable colored ink used for forming an image on the -~ 30 receiving medium is used.
The embodiment will be explained hereinafter.
An indication element of this embodiment (hereina~ter referred to as 'i~econd embodiment") is substantially the same a~ that of the above-mentioned , .
embodiment (hereina~ter referred to as "first embodiment") except tha~ the material used as the image - receiving medium in the first embodiment is used as the ` laminating material in the second embodiment, and the i , , ~. .

material used as ~he laminating material in the fir~t embodiment ls used as the image receiving medium in the second embodiment.
It is al~o enough to practice the second embodiment lf at least one of the image receiving medium and the laminating material is transparent. Usually, however, a transparent image receiving medium is used and the view from the image receiving medium embraces the image of the indication element.
When a transparent image receiving medium i9 used, a mirror reverse image is formed thereon.
A transparent laminating material may be used ~o that the vlew from the laminating material embraces ; the image of the indication element. In the case) a right~reading image i9 formed on the image receiving medium.
Fig. 5 and Fig. 6 ~how the process for producing tha indication element of the ~econd embodimemt. In Figs. 5 and 6, the same reference numerals as in Figs. 1 and 2 are used to identify the corresponding elements.
; The process ~hown in E'ig. 5 is substantially the same as the first proce~s of the first embodiment (Fig. 1) except that usually the foundation E is bonded ; 25 to the indication element D on the side of the laminating material C.
The process shown in Fig. 6 i~ substantially the same as the second process of the first embodiment (Fig. 2) except that usually a mirror reverse image is formed on a receiving medium A from an original F having a right-reading image.
According to the second embodiment, a laminating material C i3 placed on a receiving medium A
having an ink image I formed by transfer as shown in ~ 35 Fig.7 and laminated thereto, ~hereby the ink image I is `~ united to the thermoplastic resin of the surface layer of the laminating material C by the action of heat and pressure during the lamination to give an integrated ink .

The reasons therefor are that the vehicle o~
the colored ink contains a resin component which is compatible with at least the surface layer of the laminating material C and that the thermoplastic resin of the surface layer of the laminating material C has preferably a so~tening temperature lower than the laminating temperature. Accordingly, the flowing of the ink image I formed on the receiving medium A which has been encountered with the conventional method is prevented to give an indication element having a clear image.
The present invention will be more specifically described and explained by means of the following Examples. These Examples are intended to illustrate the invention and not be construed to limit the scope of the invention. It is to be understood that various changes and modifications may be made in the invention without departing from the spirit and scope thereof. In Table 2, "parts" in the formulation of transfsr ink means "parts by weight".

AND PROCESS FOR PRODUCING THE SAME
BACKGROUND OF TH~ IN~ENTION
The present invention relates to an indication element with a protective layer and a process for ; producing the same.
. . .
~; 5 There are many kinds of indication elements for -` use in sheet-like articles with a back number and other informations which are attached to the breast or back of a wear of a player in a variety of sports competitions;
name cards or tags, and nameplates or doorplates for identification of a private person or a variety of bodies such as school, company and government office; boards indicating schedules of train, streetcarl bus or the , like; a variety of information boards indicating name of ~' station, etc; boards indicating name of town or street number; and a variety of indoor or outdoor signboards.
In the case of these indication elements, the i format for a kind of indication element is unified but many kinds of products which have different indication contents with each other must be produced for every kind of indication element. For this reason, heretofore, the ~, -:.
'~ production of such indication elements was a typical case of a multikind and small-quantity production.
~(~ Accordingly, the indication elements were generally produced by hand. However, there has been a demand for automatization of the production thereof to !~ accommodate a rise in price due to a rise in labor cost and a need for shortening of a period from ordering to delivery.
' An attempt to use as an indication element a label or paper sheet on which print images were produced ~ by means of a computer or word processor was made.
i' However, any indication element of good quality was not obtained.
One of the reasons therefor is as follows: In ~ 35 the case of a conventional handwritten indication :~, ., , ~r . .: - .
1.~' : ' ', .,.' ~'..
element, an image was drew on a resin sheet by using a paint having good weatherability and abrasion resistance. However, in the case of utilizing a computer for producing print images, an ink which gave a print image having a fastness comparable to that obtained by using the conventional paint and also had a property of forming a print image on a resin sheet was unavailable.
In order to supply the poor fastness of the print image of the ink, the present inventor made an attempt that a resin ~ilm was laminated to the surface of a resin sheet on which a print image was previously formed. However, the ink of the print image was flowed by the heat and pressure during the lamination, whereby the print image was deformed so that the resulting article did not effect a function as an indication -1 element.
, As a result of the trial and error mentioned above, the present inventor has developed an indication element which has a clear image, although the element is ~i 20 produced by utili~ing a lamination technique.
:, SUMMARY OF TH~ INVENTION
The present invention provides an indication element with a protective layer which comprises a receiving medium having an image in a desired pattern on one side thereof, said image being formed by transferring a transferable colored ink of a thermal transfer ink sheet to said receiving medium; and a laminating material ~l laminated to the image-bearing side of said receiving ~ 30 medium, at least the surface layer of said receiving ; medium on the image-bearing side or a~ least the surface layer of said laminating material on the side in contact with said receiving medium being compatible with the vehicle of said transferable colored ink.

DETAILED DESCRIPTION
In accordance with the present invention, an image of the transferable colored ink transferred to the receiving medium is united either to the receiving medium in the case of using the receiving medium with the surface layer compatible with the transferable colored ink or to the laminating material in the case of using the laminating matsrial with the surface layer compatible with the transferable colored ink. The uniting is effected by application of heat and pressure during the lamination step. The image once united to the receiving medium or laminating material does not flow when it is further heated at a high temperature higher than the melting temperature of the ink during the lamination step and maintains substantially the same clear shape as that of the original image formed on ths receiving medium.
, Thus the present invention provides an indication element with a protective layer having a clear image.
Further, in accordance with the process of the present invention wherein an image is formed by a thermal transfer printing method using a thermal printer, a clear print image can be formed readily. Moreover, since an ` information processing function of a computer or the like i can be directly used in the thermal transfer printing !;.,~ 25 methodJ the production of this kind of indication element, the automatization of which was heretofore difficult due to multikind and small-quantity production, can be automatized. Accordingly, an indication element having a beautiful image comparable to that handwritten by a skilled craftsman can be obtained in a high .> productivity.
Hereinafter, the term "sheet" is intended to be a concept including a film, unless otherwise noted.
-~ According to an embodiment of the present , 35 invention, an image receiving medium wherein at least a surface layer thereof is compatible with the vehicle of a transferable colored ink used for forming an image thereon is used.

The embodiment will be explained hereinafter.
At least the surface layer of the receiving medium is composed of a thermoplastic resin compatible - with the vehicle of the transferable colored ink. It is preferable that the thermoplastic resin constituting the : surface layer has a softening temperature lower than the heating temperature in the lamination step. The uniting of an image to the surface layer of the receiving medium is more readily and completely effected, because the surface layer is softened during the larnination step.
Examples of the resin used in the receiving medium include polyamide resins preferably having a softening temperature of about 50C to about 120C;
polyurethane resins; polyester resins preferably having a 15 molecular weight of about 2 x 104 to about 3 x 10~;
ethylene-vinyl acetate copolymer resins preferably having a softening temperature of about 50C to about 90~C, butyral resins such as polyvinyl butyral, vinyl chloride-vinyl acetate copolymer resins, low desity polyethylenes, -~ 20 syndiotactic-1, 2-polybutadiene preferably having a melting temperature of about 75C to about 90C, styrene-. . .
butadiene copolymers, vinyl chloride resins, chlorinated polyethylene resins, an~ polypropylene resins.
' These resins may be used singly or as admixtures of two or more kinds thereof. Other resin or additive may be added to the above-mentioned specific resin used as a main component.
The image receiving medium used in the present ~. , . invention may be a sheet formed from the above-specified ` 30 resin per se. Alternately a sheet formed by applying the above-specified resin to another sheet material such as cloth, paper or sheet of other resin in a desired coating thickness also may be used. A thickness of 10 to 100 ~m is sufficient for the thickness of the sheet of the ~^ 35 specific resin or the coating of the specific resin.
- An adhesive may be applied to the opposite side of the receiving medium so as to bond the receiving medium to another article. Instead of the application of li .. .
. -,,~
~32398~
the adhesive, the receiving medium per se may be composed of a heat-weldable resin which may be selec~ed from the above specific resins.
A ~hin flexible sheet is used as the receiving ; 5 medium to form an image by means of a thermal printer.
If there is a possibility that, when the receiving medium is mounted in a printer, the receiving medium winds round a platen in the case that the back surface of the receiving medium possesses a heat-~eldability to the platen or has an adhesive layer, orthe receiving medium per se is too soft, a pasteboard such as release paper may be removably attached to the -~ back surface of the receiving mediumO
Any conventional thermal transfer ink sheet can be used as the thermal transfer ink sheet without particular limitation. For example, a thermal transfer ~` ink sheet wherein a heat-sensitive transfer ink layer is provided on a support including thin high density papers such as condenser paper and glassine paper, and resin films such as polyester film, polyethylene film and polycarbonate film can be suitably used.
The ink layer may be provided on the support by means of a conventional hot-melt coating or solvent coating using water or organic solvent as a solvent.
If necessary, a conventional sticking-~' preventive layer such as a silicone resin layer may be provided on the back surface of the support.
. As the heat-sensitive transfer ink layer, there .
. can be used either one-time type ink layer wherein the whole ink of selectively heated portion of the ink layer is completely transferred by one-time use, or a multi-use ; type ink layer wherein the ink of selectively heated ~ portion of the ink layer is not completely transferred by - one-time use and the same portion of the ink layer can be used plural times for transfer printing. However, the colored ink of the heat-sensitive transfer ink layer -- which is melt-transferred to the receiving medium must !`~ contain as a main component of the vehicle a resin :...
`
',~
;~: ~t , , , - , . .. .
~L3~39~2 .
compatible with the resin constituting at least the surface layer of the receiving madium.
It is preferable to use, as the compatible resin component in the colored ink, the same kind of the resin as the above-mentioned resin of the surface layer of the receiving medium used. However, a resin which is different in kind from but has substantially the same solubility parameter as the resin of the surface layer of the receiving medium can be used. Preferably the ; 10 compatible resin component is used in a proportion of ` about 3~20 by weight or more of the total amount of the vehicle of the transferable colored ink~
Some combinations of resins which are different in kind from each other but are compatible with each other are shown in Table 1. In Table 1, the item "Compatible resin component of ink vehicle" in the right column means a resin component which is contained in a vehicle of 2 transferable colored ink and which is ; compatible with the resin of a receiving medium described in the left column. With respect to each combination shown in Table 1, plural kinds of resins exemplified as the compatible resin component in the ink vehicle for a kind of resin of the receiving medium may be used singly or as admixtures of two or more kinds thereof. An incompatible resin may be used in combination with the above compatible resin component as a vehicle component with limits not to injure the purpose of the present ; invention.

These auxiliary vehicle components are selected such that the miscibility or compatibility with the above-mentioned compatible resin component, and the characteristic properties of the ink such as viscosity and melting temperature are adjusted to secure the clearness of an image. Any usual - dye or pigment can be used as a coloring agent.
Preferably the viscosity of the transferable ~ colored ink is not lower than about 2 poises at 100C.
;~ In the case of the one-time type heat-sensitive transfer ink layer, two or multi-layered structure can be ; adopted other than one-layered structure. For example, `~- 35 when the releasability of the colored ink layer from the support in transfer operation is poor, a layer composed of a wax which is reduced significantly in its viscosity when it is heated in transfer operation may be provided ", .

Further, another transferable layer containing no coloring agent may be provided on the surface of the colored ink layer to prevent an accidental ~` transferring of the colored ink to the receiving medium.
In the case of the multi-use type heat-sensitive transfer ink layer, any conventional ink layer may be used. In particular, an ink layer wherein a ' transferable colored ink is contained in an `; untransferable resinous sponge layer is preferably used.
i As the laminating material, there can be used any sheet capable of being bonded to the image-bearing surface of the receiving medium when the laminating material is pressed under heating to the receiving medium in the lamination step. The laminating material per se need not have a heat-weldability, if the receiving medium has a heat-weldability to the laminating material.
~ 20 Examples of the laminating material include films or :~ sheets of rigid polyvinyl chloride, soft polyvinyl ~i chloride, polycarbonate, polyester, acrylic resin, ., tetra~luoroethylene copolymer and difluoroethylene copolymer.
The laminating material may be a single-layered -~ sheet or a multi-layered sheet. An example of the multi-layered sheet is a sheet consisting of an acrylic resin layer, a tetrafluoroethylene copolymer layer provided on one surface of the acrylic resin layer and a soft~or hard . , vinyl chloride resin layer on the other surface of the acrylic resin layer. The thickness of the laminating material is usually from 3 to 800 ~m.
It is enough to practice the present invention if at least one of the laminating material and the '~ 35 receiving medium is transparent. Usually, howsver, a ~ transparent laminating material is used and the view from ''~ k' the laminating material embraces the image of the ~, indication element.

When a transparent laminating materLal is used, a right-reading image can be formed on the receiving medium.
A transparent image receiving medium may be used so that the view from the receiving medium embraces the image of the indication element. In that case, mirror reverse images are formed on the receiving medium.
A weatherability of the indication element can be improved by incorporating an ultraviolet absorber or analogous additive into at least one or all of the - laminating material, the receiving medium and a foundation mentioned below.
Some embodiments of the process for producing ; the indication element of the present invention will be explained by referring to the drawings.
.~ First Process (Fig. 1) , Signals corresponding to a pattern processed by a computer 1 such as personal computer are input into a heat-sensitive transfer printer 2, wherein an image corresponding to the pattern is printed on a receiving medium A by using the thermal transfer ink sheet B.
The receiving medium A on which the print image is formed i9 fed together with a transparent laminating ; material C into a laminator 3, wherein the lamination i~
: ,~
~ 25 carried out at a temperature hi~her than the softening :~ temperature of the thermoplastic resin constituting the receiving medium to give an indication element D.
Usually the heating temperature for the lamination is from 70 to 150C.
After the lamination step, if necessary, the 'r ndication element 3 may be bonded to a foundation E on ~; the side of the receiving medium A. If the receiving ` medium A has a heat~weldability to the foundation E, the :~ indication element D can be welded to the foundation E on .,s the side of the receiving medium A by means of a hot press machine 4.
~ Any suitable article can be used as the ,~ foundation E depending upon the use of the indication . .

, . . .
~323~82 element D. Examples of` the foundation E include plates or sheets of materials such as metal, synthetic re~in or wood and fabrics of natural or synthetic fiber.
Further, in the lamination step, the lamination and the bonding to the foundation may be effected simultaneously by putting the laminating material C on the ~ront surface of the receiving medium A while putting the foundation E on the back surface of the receiving medium A, and applying a pressure to the assembly under heating.
Moreover, in the case of an indication element D wherein a transparent receiving medium A is used and a mirror reverse image is formed on the transparent receiving medium A and a laminating material C which may be opaque is laminated to the receiving medium A, the ~ foundation E is bonded to the indication element D on the - side of the laminating material C.
Second_process (Fig. 2) - It is possible to ~orm an image on the receiving medium by utilizing a hot ray instead of a printer.
According to this process J an original F having an image formed by using a substance having a radiation absorbing property such as carbon black is prepared. The original F is placed on the back surface of thermal transfer ink sheet B which is placed on the receiving medium on the side of the ink layer. If a thin receiving medium is used, the original F can be placed on the back ~ surface of the receiving medium. The assembly is - 30 irradiated with a hot ray such as infrared ray, whereby "'J portions of the ink layer corresponding to the image of the original F are molten and transferred to the receiving medium. Subsequent procedures are the same as those of the first process mentioned above.
When the second process is adopted, there can be used an image receiving medium which is previously bonded to a foundation, or a material which is hard at ordinary temperatures, a thick sheet or plate material or . .

~ 3~3982 a thick cloth as the image receiving medium.
In the case of these receiving media which are used with difficulty in a usual printer, an image can be formed thereon by using a small-sized printer which can ; 5 be moved manually or automatically on a desk.
According to the present invention, a laminating sheet C is placed on a receiving medium A
having an ink im~ge I formed by transfer as shown in Fig 3 and laminated thereto, whereby the ink ima~e I is united to the thermoplastic resin of the surface layer of the receiving medium A by the action of heat and pressure during the lamination to give an integrated ink image I' as shown in Fig. 4.
The reasons therefor are that the`vehicle of the colored ink contains a resin component which is compatible with at least the surface layer of the receiving medium A and that the thermoplastic resin of the surface layer of the receiving medium A has preferably a softening temperature lower than the laminating temperature. Accordingly, the flowing of the ink image I formed on the receiving medium A which has `~ been encountered with the conventional method is prevented to give an indication element having a clear image.
According to another embodiment of the present invention, a laminating material wherein at least the ;
surface layer thereof on the side in contact with the receiving medium is compatible with the vehicle of a transferable colored ink used for forming an image on the -~ 30 receiving medium is used.
The embodiment will be explained hereinafter.
An indication element of this embodiment (hereina~ter referred to as 'i~econd embodiment") is substantially the same a~ that of the above-mentioned , .
embodiment (hereina~ter referred to as "first embodiment") except tha~ the material used as the image - receiving medium in the first embodiment is used as the ` laminating material in the second embodiment, and the i , , ~. .

material used as ~he laminating material in the fir~t embodiment ls used as the image receiving medium in the second embodiment.
It is al~o enough to practice the second embodiment lf at least one of the image receiving medium and the laminating material is transparent. Usually, however, a transparent image receiving medium is used and the view from the image receiving medium embraces the image of the indication element.
When a transparent image receiving medium i9 used, a mirror reverse image is formed thereon.
A transparent laminating material may be used ~o that the vlew from the laminating material embraces ; the image of the indication element. In the case) a right~reading image i9 formed on the image receiving medium.

; The process ~hown in E'ig. 5 is substantially the same as the first proce~s of the first embodiment (Fig. 1) except that usually the foundation E is bonded ; 25 to the indication element D on the side of the laminating material C.
The process shown in Fig. 6 i~ substantially the same as the second process of the first embodiment (Fig. 2) except that usually a mirror reverse image is formed on a receiving medium A from an original F having a right-reading image.
According to the second embodiment, a laminating material C i3 placed on a receiving medium A
having an ink image I formed by transfer as shown in ~ 35 Fig.7 and laminated thereto, ~hereby the ink image I is `~ united to the thermoplastic resin of the surface layer of the laminating material C by the action of heat and pressure during the lamination to give an integrated ink .

The reasons therefor are that the vehicle o~
the colored ink contains a resin component which is compatible with at least the surface layer of the laminating material C and that the thermoplastic resin of the surface layer of the laminating material C has preferably a so~tening temperature lower than the laminating temperature. Accordingly, the flowing of the ink image I formed on the receiving medium A which has been encountered with the conventional method is prevented to give an indication element having a clear image.
The present invention will be more specifically described and explained by means of the following Examples. These Examples are intended to illustrate the invention and not be construed to limit the scope of the invention. It is to be understood that various changes and modifications may be made in the invention without departing from the spirit and scope thereof.
