Definitions
- the present invention has a surface formed with a pattern, and has a visual unevenness due to a difference depending on the pattern, is excellent in durability of the surface including the pattern, and has a surface such as wear resistance.
- the present invention relates to a decorative material having not only strength but also marring resistance and oil resistance.
- decorative decorative boards for furniture and kitchen product cabinets for example, decorative materials in which wood-based materials, inorganic materials, synthetic resin-based materials, metal-based materials such as steel plates, etc., are printed with a wood grain pattern, for example.
- seat with the adhesive agent is used.
- the decorative sheet used for such a surface decorative board has appropriate flexibility, machinability, rupture resistance, etc. for secondary covering such as laminating, lapping and V-cut covering.
- Various properties such as suitability, weather resistance in use, light resistance, heat resistance, water resistance, solvent resistance, surface hardness, wear resistance, and scratch resistance are required.
- a base material that sufficiently satisfies the above processability is used, and a surface protective layer is applied to the surface of the base material, and an ionizing radiation curable resin composition is preferably used.
- the ionizing radiation curable resin composition is a composition that is cured by ionizing radiation such as ultraviolet rays and electron beams, and when this composition is used, the surface protective layer can be applied and formed without a solvent without using an organic solvent. Since it is environmentally friendly and has a high crosslink density, various advantages such as easy wear and other surface strength can be obtained.
- an electron beam curable paint or photocuring by a painted surface provided in a pattern on a substrate After forming an area where the wettability with respect to the mold paint is different from that of the substrate surface, an electron beam curable paint or a photocurable paint is applied on the substrate and applied in the area where the paint is easily wetted.
- a method has been proposed in which the surface of the coating is depressed and the surface of the paint is raised in an area that is difficult to wet (see, for example, Patent Document 1 and Claims).
- this method has a problem that the concave and convex portions do not appear cleanly when the concave portion, that is, the easily wettable area is thin.
- a concave-convex pattern can be obtained on the surface of the base material, but in the boundary area between the concave part and the raised part, the surface is transferred from the convex part to the concave part due to the surface tension of the paint.
- the rounded edge is rounded and lacks the sharpness of the projections and depressions, and there are protrusions that are higher than the height of the bumps. For example, in the case of a wood grain pattern, the appearance and feel that feels realistic is good. There is a problem.
- a film on which a multicolor pattern is printed with an ink containing a retarder that delays the curing of the resin-free paint and an ink that does not contain it is pre-applied on the substrate!
- a method has been proposed in which a film is coated on a non-solvent solvent-free paint, cured in a curing atmosphere, and then peeled off and transferred! (Refer to Patent Document 2 and Claims). According to this method, it is possible to dent and transfer only the color pattern portion printed with the ink containing the curing retarder. However, this method requires special inks and has the problem that the curing reaction of the non-solvent coating resin coating is unstable.
- this method can be used for example when wood grain tone is desired, i.e., when there are mostly concave parts with a very narrow width, such as a wood grain conduit groove.
- the concave portion is buried by the flow of the paint that composes, and the force is inappropriate because the degree of filling varies, and because it is physically uneven, the touch feeling is not good. There's a problem.
- an ultraviolet curable printing ink containing a matting agent on thin paper and irradiating it with an actinic ray, it is then coated with a high gloss UV curable printing ink.
- a decorative paper having a wood grain pattern in which a pattern is printed and irradiated with actinic rays has been proposed (see Patent Document 4 and claims).
- the portion using the high glossy ink appears to be a convex portion
- the portion of the ink containing the decoloring agent appears to be a concave portion, so that a wood texture can be obtained.
- the decorative paper proposed here does not have an overcoat transparent coating as a protective coating, so the so-called conduit ink portion for printing the wood grain pattern is weatherproof, water resistant
- the durability, wear resistance, scratch resistance, etc. are inevitably lowered, resulting in poor durability.
- a pattern is provided with an ionizing radiation shielding material on either the front or back surface of the ionizing radiation transmitting release substrate having a peelable surface, and the release substrate and an uncured product of ionizing radiation curable resin on the surface are provided.
- the substrate for forming a concavo-convex pattern having a layer is overlapped and irradiated with ionizing radiation from the peeling substrate side, and only the ionizing radiation curable resin corresponding to the non-patterned portion formed of the ionizing radiation shielding material is applied.
- this method has a disadvantage in that it requires a material such as a peeling material or an ionizing radiation shielding material, and the method of adhering and removing uncured resin on the peeling substrate has a deep and clear concave portion. Has the disadvantage that it cannot be formed. Further, when an electron beam curable resin is used as the ionizing radiation curable resin, there is a drawback that it is difficult to select a material that shields the electron beam.
- a roll press in which a synthetic resin that performs radiation polymerization is applied to a substrate on which a print or decorative paper is pasted, and then irradiation is stopped when the synthetic resin is in a semi-cured state to give a concavo-convex pattern
- a method of manufacturing a decorative board having a concavo-convex pattern in which a synthetic resin is completely cured after being pressed with a cold-pressed body such as the like has been proposed (for example, see Patent Document 6 and Claims). ).
- an electron beam curable resin is applied on the base material using a coating device, and it is cured by irradiating with an electron beam while shaping the unevenness of the mold roll by making contact with the mold roll in the electron beam irradiation machine.
- a method of continuously forming irregularities has been proposed (see, for example, Patent Document 7, scope of patent request, Fig. 1).
- this method requires a special mold roll device, which has the disadvantage that it cannot form irregularities with a normal printing device, and there is a limit to the speed of shaping with the mold roll. The disadvantage is that productivity is low.
- the surface of the substrate has a coating layer, a pattern layer, and a surface protective layer obtained by crosslinking and curing the ionizing radiation curable resin composition, and the pattern layer is compared with the coating layer.
- a cosmetic material having a high permeability of the ionizing radiation curable resin composition has been proposed (see, for example, Patent Document 8, Claims, FIG. 1 and FIG. 2). According to this decorative material, since the ionizing radiation curable resin composition easily penetrates into a portion where a pattern exists, a concave portion is formed in the portion, and a decorative material having an uneven surface is obtained.
- the pattern layer is porous Since it becomes brittle, the durability and contamination resistance of the recesses are reduced.
- a recess having a sufficient depth and sharpness cannot be formed if an attempt is made to suppress the porosity of the pattern layer in order to improve the durability and stain resistance of the recess.
- this cosmetic material is physically uneven, there is room for further improvement in that the feel is not good.
- the surface protective layer is composed of a cross-linked cured product of ionizing radiation curable resin
- the decorative material when used for a shelf of a kitchen shelf, the edible oil attached to the surface reaches the inside. It may permeate, or may become a so-called wet color in which the transparency of the permeation portion increases and the surface looks wet.
- the surface protective layer can be formed as a dense layer, so that the oil does not penetrate under the surface protective layer and does not have a wet color.
- ionizing radiation curing tends to be harder than thermosetting resin.
- a decorative material provided with a surface protective layer made of synthetic rosin its flexibility is lowered and it becomes difficult to store it in a roll form.
- the material cost is high. Therefore, from the viewpoint of storage, cost, etc., the thickness of the surface protective layer is usually 10 m or less, and it is desirable to make it as thin as possible.
- marring resistance is also an important factor. This is a flaw resistance required separately even if surface strength such as wear resistance is sufficiently obtained by using a cross-linked cured product of ionizing radiation curable resin for the surface protective layer.
- wear resistance we have usually dealt with hardening the surface protective layer by adding silica particles or the like as a filler in the surface protective layer. In that case, wrinkles could rise due to the collection of very fine scratches. For example, when a large number of decorative plates are stacked and the surface of the decorative material is rubbed by vibration during transportation, a certain wrinkle may have an increase in wrinkles due to the collection of scratches during handling in the decorative plate production line. there were.
