(57) [Summary] [Object] To provide a coating material composition useful for forming an undercoat layer for vapor deposition, which is excellent in adhesion, heat resistance and surface smoothness, on a polyolefin resin molded product. [Structure] (A) 0.1 to 50 parts by weight of a chlorinated polyolefin having a chlorine content of 50% or less, (B) a polyfunctional monomer having three or more (meth) acryloyloxy groups in one molecule. (B-1) 20 to 100% by weight and 1 in 1 molecule 1 to 2 having 2 (meth) acryloyloxy groups 10 to 80 parts by weight of a monomer mixture consisting of 80 to 0% by weight of the functional monomer (b-2), 1 to 80 parts by weight of (C) an acrylic copolymer, and (D) a photopolymerization initiator 0. 1 to 15 parts by weight of the coating material composition |
