Actinic-light-curable composition, molded polycarbonate resin object with a cured film, and manufacturing method therefor

摘要

Disclosed is an active energy ray-curing composition containing an active energy ray-curing prepolymer (A) obtainable by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group, an active energy ray-curing compound (B) having a benzotriazole group, another active energy ray-curing compound (C) differing from the (A) component and the (B) component, and inorganic oxide particles (D). The acrylic-based prepolymer having the hydroxyl group is a copolymer that includes an acrylic monomer (a1) having a piperidinyl group, an acrylic monomer (a2) having a hydroxyl group, etc., as monomer units.
