PURPOSE:To improve optical resistance, dying adherence by employing ultraviolet curable resin as a colorant image receiving layer, and incorporating specific amount of ultraviolet ray absorber in the curable resin. CONSTITUTION:0.05-3pts.wt. of ultraviolet ray absorber is contained in ultraviolet curable resin. The curable resin uses oligomer selected from a group consisting of polyol acrylate, polyester acrylate, epoxy acrylate and urethane acrylate. The absorber is added with compound of benzphenone, benztriazole, succirate to improve its optical resistance. |
