As the base material film 11, a polyethylene film, a polypropylene film, a polyester film, a polyimide, a polyetherimide, a polysulfone, a polyetheretherketone or the like is used, which transmits an electron beam and does not firmly adhere to the electron beam-curable resin layer, and thus is easy. Select and use one that can be peeled off. As the electron beam curable resin 12, a resin having a radically polymerizable unsaturated group to which a colorant is added or not added can be used. For example, it can be selected from various acrylates such as polyester acrylate, urethane acrylate, 2-hydroxyethyl acrylate and neopentyl glycol diacrylate, methacrylates and styrene monomers. The resin 12 is applied onto the film 11 by an application method such as roll coating. As the paper 13, thin paper, inter-paper reinforcing paper, paper with a sealer (for example, urethane sealer), impregnated paper, or non-woven fabric other than paper can be considered. Furthermore, it is selected from the above-mentioned papers and non-woven fabrics which are printed. Preferably, thin paper or inter-paper reinforced paper of 23 to 50 g / m 2 is desirable. Since the resin of the composite decorative sheet 1 is uncured, it is subsequently subjected to electron beam irradiation curing.
照射方向は、基材フィルム面側および紙面側あるいはど
