The present invention is directed to a thermoplastic resin composition comprising specific amounts of (A) a saturated polyester resin, (B) a rubber-reinforced styrene base resin which can be obtained by copolymerizing a vinyl monomer, a cyanated vinyl monomer and another copolymerizable vinyl monomer in the presence of a rubbery polymer, (C) an epoxy-modified copolymer which comprises an aromatic vinyl monomer, a cyanated vinyl monomer, an ethylenically unsaturated epoxy group-containing monomer and another copolymerizable vinyl monomer, and (D) a styrene base copolymer which comprises an aromatic vinyl monomer, a cyanated vinyl monomer and another copolymerizable vinyl monomer, wherein the content of the rubbery polymer is from 5 to 40% by weight and the content of the ethylenically unsaturated epoxy group-containing monomer is at least 0.001% by weight based on the whole weight of the composition. The resin composition of the present invention has good chemical resistance and impact resistance properties.
