PURPOSE:To obtain the titled composition capable of forming coating films having excellent scratch resistance, durability, etc., curable with active energy rays, by blending a monomer component comprising a specific polyfunctional (meth)acrylate, etc., with an organic solvent and a photopolymerization initiator. CONSTITUTION:(A) 100pts.wt. monomer component consisting of A1: 70-95wt.% polyfunctional (meth)acrylate containing three or more (meth)acryloyloxy groups in the molecule, 5-30wt.%. A2: maleimide compound shown by formula I (R1 is monofunctional alicyclic hydrocarbon) and/or A3: cycloalkyl (meth)acrylate monomer shown by formula II (R2 is H, etc.; R3 is monofunctional alicyclic hydrocarbon) and 0-25wt.% nonvolatile polymerizable monomer except the components A1-A3) is blended with (B) 10-900pts.wt. organic solvent and (C) 0-10pts.wt. photopolymerization initiator to give a composition, which is applied to a resin molded article (e.g. polymethyl methacrylate, etc.) and cured by active energy. |
