A polycarbonate resin composition comprising (A) 100 parts by weight of a polycarbonate resin, and (B) 1 to 80 parts by weight of an acrylic ester graft copolymer. The acrylic ester graft copolymer is produced by grafting on 100 parts by weight of an acrylic ester copolymer produced by copolymerizing (i) 100 parts by weight of at least one acrylic ester monomer having 1 to 16 carbon atoms and (ii) 0.1 to 5 parts by weight of a polyfunctional allyl ester monomer and/or a polyfunctional methallyl ester monomer having a benzene ring as a skeleton; a copolymer of (iii) 15 to 100 parts by weight of (a) one or two vinyl monomers selected from the group consisting of a methacrylic ester, an aromatic monovinyl compound and a vinyl cyanide compound, and (b) an acrylic ester in an amount of 0 to 20% by weight to the vinyl monomer and (iv) 0.1 to 5 parts by weight of a polyfunctional allyl ester monomer and/or a polyfunctional methallylester monomer having a benzene ring as a skeleton. The polycarbonate resin may additionally contain 4 to 150 parts by weight of an aromatic polyester resin (C). The polycarbonate resin composition is excellent in low temperature impact resistance, thermal stability, solvent resistance and is useful as a molding material.
