<P>PROBLEM TO BE SOLVED: To provide a resin composition for coating a polystyrene-based resin, which serves as a surface material and is excellent in adhesion to a PS resin or a waste resin thereof as a base resin, as well as capable of providing coated moldings excellent in workability and durability, and moreover having excellent matting properties. <P>SOLUTION: The resin composition for coating a polystyrene-based resin comprises (A) a graft copolymer produced by polymerizing a vinyl monomer mixture including an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a rubbery polymer and (B) a vinyl copolymer produced by copolymerizing a vinyl monomer mixture including an aromatic vinyl monomer and a vinyl cyanide polymer, wherein the content of the vinyl cyanide monomer in the vinyl monomer mixture used in the graft copolymer (A) is 5-20 mass%, and preferably, the content of the vinyl cyanide monomer in the vinyl monomer mixture used in the vinyl copolymer (B) is 5-23 mass%. <P>COPYRIGHT: (C)2012,JPO&INPIT |
