ABSTRACT:
A thermoplastic resin composition comprising 10 to 98 parts by weight of a graft polymer (1A) containing a rubber-like polymer (1G) having a diene unit content of 50% by weight or less, 2 to 50 parts by weight of a hydroxyl group-containing acrylic copolymer (1B) and 0 to 80 parts by weight of other thermoplastic resin (1F), wherein the rubber-like polymer (1G) is at least one selected from the group consisting of a diene-based rubber, a polyorganosiloxane-based rubber and an olefin-based rubber; and, a graft copolymer (2A) obtained by grafting a vinyl-based polymer to a (meth)acrylate-based rubber-like polymer (2G) expansion-treated with an acid group-containing copolymer latex (2K) wherein the (meth)acrylate-based rubber-like polymer contains two or more poly-functional monomer units.
