Description of the Related Art Conventionally, as a method of manufacturing a decorative sheet for the above-mentioned purpose, a UV-curable resin is applied, and a printing film is printed on a thermoplastic film cured by irradiating UV rays. After laminating from the back surface so as to be in contact with the back surface of the surface coated with the ultraviolet curing resin, a method of embossing the surface of the ultraviolet curing resin, applying the ultraviolet curing resin on the printed surface of the printed thermoplastic film, A method of irradiating ultraviolet rays from above the application surface of the ultraviolet curable resin, embossing the surface of the cured ultraviolet curable resin, applying the ultraviolet curable resin to the printed back surface of the printed thermoplastic film, and applying the ultraviolet curable resin. Method of irradiating ultraviolet rays from above the application surface and embossing the surface of the cured ultraviolet curing resin, transparent thermoplastic resin coated with ultraviolet curing resin There has been a method in which irregularities of an embossing roll are adhered to a resin-coated surface of a fat film, and the ultraviolet-curable resin is cured by ultraviolet light transmitted through the film from the film side to form an irregular pattern.

その二つの要求を同時に完全に満たす樹脂はなく、未だ
に満足のいくものは出来ていない。However, in the case of (1), it is necessary to use a UV-curable resin which is suitable for embossing and has excellent scratch resistance on the cured surface.
No resin fully satisfies these two requirements at the same time, and no satisfactory products have yet been made.

てしまっていた。In addition, in the case of (1), since the coating is performed on the printing surface, the effect of the curing by the ultraviolet rays reflected from the base sheet during the irradiation of the ultraviolet rays is absorbed depending on the printing residue, and the curing is not sufficient. And also had unevenness.
【０００５】また、の場合、エンボス加工特に印刷面

るばかりか、硬化にムラができる原因ともなりうる。In such a case, it is possible to obtain a vivid embossed pattern with clear irregularities. However, when the resin is printed on a thermoplastic film in advance, the amount of ultraviolet irradiation to the resin is reduced by the printed pattern, and Not only insufficient curing, but also a cause of uneven curing.

といった問題がある。Also, the method of printing on the back side of the resin-coated surface after curing the resin also has a problem that it is difficult to perform printing due to heat during irradiation with ultraviolet rays and distortion of the thermoplastic film due to shrinkage of the resin during curing of the resin.

1 is a schematic view of a manufacturing apparatus showing an example of a method for manufacturing a concave and convex decorative sheet having scratch resistance according to the present invention. A transparent thermoplastic film made by Riken Vinyl Co., Ltd .: "Polyvinyl chloride R type, UV transmittance 315 nm 50%, 360 nm 60%" is used, and gravure coating is applied to the UV curable resin (Mitsubishi Rayon Co., Ltd.) : “UL3160”) was applied at a film thickness of 15 μm, and the resin was cured by irradiating ultraviolet rays from the polyvinyl chloride film side with an ultraviolet irradiation device in a state of being in close contact with an embossing roll having a plate depth of 10 to 15 μm. afterwards,
As the transfer film, an ink composed of a vinyl chloride-vinyl acetate copolymer resin (manufactured by Toyo Ink Mfg. Co., Ltd .: “VCG
TK ") was used as a transfer film printed on a polyethylene terephthalate film, and this was heat-laminated on the resin-coated back surface after the UV-curable resin was cured. After cooling this with a cooling roll, the polyethylene terephthalate film was peeled off to obtain an uneven decorative sheet having scratch resistance.
