を設けることができないという問題があった。<Prior Art> Conventionally, as a method for producing high gloss paper, there is a method of coating the surface of a base material with an ultraviolet ray or electron beam curable resin by roll coating or blade coating, and curing the resin. Although this method provides a smooth coated surface, there is a problem in that it is not possible to provide an uncoated portion on the surface of the substrate.
また、グラビアコート法、オフセット印刷法にて紫外線

工部分を有するパターン印刷は可能であるが、平滑性が
劣るという問題があった。Further, there are methods of coating with an ultraviolet curable resin using a gravure coating method and an offset printing method. Although this method allows pattern printing with uncoated areas, there is a problem in that the smoothness is poor.
一方、グラビアコート法にて熱可塑性樹脂をコートした
後、コートした樹脂を熱プレスする方法がある。この方
法ではパターン印刷は可能であり、しかも平滑性の良い
高光沢紙を得ることができる。On the other hand, there is a method of coating a thermoplastic resin using a gravure coating method and then hot pressing the coated resin. With this method, pattern printing is possible and high gloss paper with good smoothness can be obtained.
しかし、熱プレス工程は加工速度が遅く生産性が悪いと
いう問題、及び熱可塑性樹脂は耐薬品性、耐摩耗性が弱
いという問題があった。However, the hot press process has problems such as slow processing speed and poor productivity, and thermoplastic resins have low chemical resistance and abrasion resistance.

化させてしまうという問題があった。However, in this method, the electron beam cures the resin after passing through the base material, so if cardboard is used as the base material, the energy of the electron beam is low enough to harden the resin after passing through the base material. Since the resin does not have sufficient energy, the energy of the electron beam must be increased, and in order to cure the resin, increasing the energy of the electron beam has the problem of degrading the base material.
