ACTIVE ENERGY RAY CURABLE UNDERCOAT AGENT AND SURFACE COATED MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray curable undercoat agent high in curing speed and suitable for evaporation with a methacrylic resin and an inorganic product, and a surface coated molded body having high adhesion with an inorganic layer on a surface of the methacrylic resin molded body.SOLUTION: There are provided an active energy ray curable undercoat agent containing a (meth)acrylic block copolymer (A) consisting of a (meth)acrylic polymer block (a) having an active energy ray curable group containing a partial structure (1) represented by the following general formula (1) and an acrylic polymer block (b) having no active energy ray curable group, and a surface coated molded body having an undercoat layer by curing the active energy ray curable undercoat agent on a surface of a methacrylic resin molded body and having an inorganic layer on a surface of the undercoat layer. (1), where Rrepresents a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms.SELECTED DRAWING: None
