Abstract
A thermoplastic resin composition exhibiting good balance of mechanical properties, heat resistance, flowability, and size stability as well as excellent stability in retention in the molding, appearance of the molded article, and coating properties, and also, a molded article thereof are provided. The thermoplastic resin composition is a blend of a polycarbonate resin (I), a graft copolymer (II) which comprises a graft copolymer (II-1) prepared by graft polymerization of a monomer mixture containing an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of a diene rubbery polymer or a graft copolymer (II-2) prepared by graft polymerization of a monomer mixture containing an aromatic vinyl monomer and a vinyl cyanide monomer in the presence of an acryl rubbery polymer, a vinyl copolymer (III) prepared by copolymerizing an aromatic vinyl monomer and a vinyl cyanide monomer, a crystalline resin (IV), and a plate-shaped inorganic filler (V), and when total amount of (I)+(II)+(III)+(IV)+(V) is 100% by weight, (I) is 50 to 70% by weight, (II) is 3 to 15% by weight, (III) is 10 to 25% by weight, (IV) is 1 to 9% by weight, and (V) is 10 to 20% by weight, and content ratio of (IV) to 100% by weight of (V) is at least 10% by weight and less than 50% by weight.
