DECORATING MOLDING METHOD FOR THERMOPLASTIC RESIN MOLDING

摘要

PROBLEM TO BE SOLVED: To easily provide a molding whose protective layer has sufficient physical properties without performing after-coating by adding a photopolymerization initiator to an acrylic copolymer and a compound having a (meth)acryloyl group at a specific ratio to produce a photopolymerizable resin composition. SOLUTION: A photopo1ymerizable resin composition forming a protective layer consists of 40-60 pts.wt. acrylic copolymer, 60-60 pts.wt. compound (wherein, an acrylic copolymer is removed.) having (meth)acryloyl groups of at least three pieces in a molecule and a photopolymerization initiator. In the acrylic copolymer, a (meth)acryloyl group is introduced into the glycidyl group of a side chain and the (meth)acryloyl group of at least one piece is contained in a molecule and glass transition temperature of a main chain is 40-120 deg.C and weight-average molecular weight is 10,000-200,000. Then, a flexible decorating film 25 in which the compoairion is applied and dried to form a protective layer 21 is set in a mold and a thermoplastic material is injected and molded. The surface of a molding is irradiated with ultraviolet rays to cure the protective layer 21.
