THERMOPLASTIC RESIN COMPOSITION, MOLDED ARTICLE AND COATED MOLDED ARTICLE

摘要

A thermoplastic resin composition, comprising:
an aromatic polycarbonate (A);a copolymer mixture (B) comprising a copolymer (b1) of a vinyl cyanide-based monomer and one or more kinds of monomers copolymerizable with said vinyl cyanide-based monomer, and a graft copolymer (b2) of a vinyl cyanide-based monomer, one or more kinds of monomers copolymerizable with said vinyl cyanide-based monomer and a rubbery polymer; andat least one kind of metal atom selected from the group consisting of Mg, Al and Ca,wherein the copolymer mixture (B) comprises an acetone-soluble component,wherein said acetone-soluble component has at least two peak tops, being peak top 1 and peak top 2, within the range of 15 to 50% of vinyl cyanide component content rate, when measuring the vinyl cyanide component content rate by high performance liquid chromatography,wherein the peak top 1 is present in the range of 15% or more to 30% or less of vinyl cyanide component content rate,wherein the peak top 2 is present in the range of from more than 30% to 50% or less of vinyl cyanide component content rate, andwherein the total content of the metal atoms is 10 to 1000 ppm, based on 100 parts by mass of total amount of the aromatic polycarbonate (A) and the copolymer mixture (B).
