1. A thermoplastic resin composition, comprising:
(A) about 40 to about 70% by weight of a polycarbonate resin; (B) about 20 to about 40% by weight of an acrylate-styrene-acrylonitrile (ASA) graft copolymer having a shell containing 50 to about 80% by weight styrene and about 20 to 50% by weight acrylonitrile based on the total weight of the shell; (C) about 9 to about 29% by weight of a random copolymer of an alkyl(meth)acrylate, an aromatic vinyl compound, and a vinyl cyanide compound; and (D) greater than or equal to about 0.1% by weight and less than or equal to about 5% by weight of a copolymer of an aromatic methacrylate and a monofunctional unsaturated monomer, each based on the total weight of the thermoplastic resin composition, wherein the amount of the alkyl(meth)acrylate compound in the random copolymer (C) of an alkyl(meth)acrylate, an aromatic vinyl compound, and a vinyl cyanide compound ranges from about 50% by weight to about 89% by weight based on the total weight of the random copolymer (C) of an alkyl(meth)acrylate, an aromatic vinyl compound, and a vinyl cyanide compound, wherein the copolymer (D) of an aromatic methacrylate and a monofunctional unsaturated monomer includes a copolymer of an aromatic methacrylate represented by Chemical Formula 1 and a monofunctional unsaturated monomer: wherein m is an integer of 0 to 10, Y is a single bond, —O—, or —S—, and Ar is phenyl, methyl phenyl, methyl ethyl phenyl, propyl phenyl, methoxy phenyl, cyclohexyl phenyl, chloro phenyl, bromo phenyl, phenyl phenyl, or benzyl phenyl, with the proviso that when m is 0 or 1 then Y is a single bond wherein the monofunctional unsaturated monomer in the copolymer (D) comprises a (meth)acrylic acid ester, and wherein the copolymer (D) of an aromatic methacrylate represented by Chemical Formula 1 and the monofunctional unsaturated monomer has a weight average molecular weight of about 8,000 g/mol to about 15,000 g/mol. |
