影響する。[0003] In this method of applying an inorganic fine powder and a release agent to an electron beam-curable resin, the inorganic fine powder and the release agent are uniformly distributed in the applied resin. Large quantities of release agents are required. By adding inorganic fine powder to the electron beam-curable resin, the abrasion resistance and scratch properties of the surface properties are improved, but the surface of the decorative sheet coated with the electron beam-curable resin containing the inorganic fine powder has poor design. ,
Use of a large amount of the inorganic fine powder affects the curing inhibition of the electron beam-curable resin.

And physical properties such as wear resistance and scratch resistance are improved. In addition, the surface is smoothed by the film by transferring with wet lamination. Furthermore, since the surface of the electron beam-curable resin is covered with a film coated with a release agent containing inorganic fine powder at the time of electron beam irradiation, it also has an effect of protecting the surface.

It shows good results in physical properties such as wear resistance and scratch resistance, and also has good surface smoothness. In the manufacturing method, the operation of peeling off the film is not necessarily performed in-line, and the film can be peeled off in a subsequent step, so that the film has an effect of protecting the surface.
