影響する。In this method of mixing the electron beam curable resin with the inorganic fine powder and the release agent, the inorganic fine powder and the release agent are evenly distributed in the applied resin, so that the inorganic fine powder and the release agent are uniformly distributed. A large amount of release agent is required. By adding inorganic fine powder to the electron beam curable resin, the surface properties such as abrasion resistance and scratch resistance are improved, but the surface of the decorative sheet coated with the electron beam curable resin containing the inorganic fine powder is not well designed. ,
The use of a large amount of inorganic fine powder affects the inhibition of curing of the electron beam curable resin.
