ACTIVE ENERGY BEAM-CURABLE RESIN COMPOSITION, RESIN MOLDING, AND METHOD FOR PRODUCING RESIN MOLDING

摘要

Provided are: a resin composition with which it is possible to form a cured film having excellent weather resistance and wear resistance; and a resin molding having said cured film. An active energy beam-curable resin composition containing a radical polymerizable compound and a photopolymerization initiator (d), wherein said radical polymerizable compound contains 57-90 mass% of (a) caprolactone-modified mono- or poly-penta erythritol poly (meth)acrylate represented by formula (1) and 10-43 mass% of (b) urethane (meth)acrylate synthesized from a polycarbonate polyol having a branched alkyl structure and an average molecular weight falling within the range of 500-1000, a diisocyanate having an alicyclic structure, and a mono (meth)acrylate containing a hydroxyl group. In formula (1), each X independently represents a caprolactone-modified (meth)acryloyl group, a (meth)acryloyloxy group, or a -OH group.
