Resin composition for plating, and plated molded article

A method for enhancing the plating property of a molded product, which comprises providing a resin composition,

• wherein the resin composition for plating comprises a polycarbonate resin (A), a graft copolymer (B) and a copolymer (C), and satisfies the following conditions (1) to (5):
• (1) a content of the polycarbonate resin (A) is 20 to 55% by mass based on 100% by mass of a total of (A), (B) and (C);
• (2) the graft copolymer (B) is a graft copolymer obtained by graft polymerization of a rubbery polymer and styrene and acrylonitrile;
• (3) the copolymer (C) is a copolymer obtained by polymerization of styrene and acrylonitrile;
• (4) a content of the rubbery polymer is 7 to 20% by mass relative to the resin composition;
• and
• (5) a total content of oligomer components being measured at INJ temperature of 230° C. using gas chromatography are a dimer of styrene, a dimer of acrylonitrile and styrene, a trimer of styrene, and a trimer of acrylonitrile and styrene is less than 1% by mass relative to the resin composition,
• wherein the content of the copolymer obtained by graft polymerization of styrene and acrylonitrile to the rubbery polymer, which is the content of the graft copolymer (B) minus the content of styrene and acrylonitrile that are not grafted to the rubbery polymer, is 5 to 30% by mass of the total of the polycarbonate resin (A), the graft copolymer (B) and the copolymer (C),
• wherein the content of the copolymer (excluding one obtained by graft polymerization to the rubbery polymer) of styrene and acrylonitrile, which is the content of the copolymer (C) plus the content of a copolymer of styrene and acrylonitrile that are not grafted to the rubbery polymer, is 20 to 75% by mass of the total of the polycarbonate resin (A), the graft copolymer (B) and the copolymer (C).
