  • Patent number: 9605146
    Abstract: 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; and at 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
