The present invention relates to a thermoplastic resin composition, and more specifically to a thermoplastic resin composition comprising, based on the total weight of the thermoplastic resin composition: a) from 20 to 60 parts by weight of a first graft copolymer polymerised from an aromatic vinyl compound and a vinyl cyanide compound on a rubber latex; b) from 0.1 to 40 parts by weight of a second copolymer polymerised from a (meth)acrylic acid alkyl ester compound, an aromatic vinyl compound, and a vinyl cyanide compound; and c) from 40 to 80 parts by weight of a third copolymer polymerised from a (meth)acrylic acid alkyl ester compound, an aromatic vinyl compound and an acid anhydride. The present invention can provide a thermoplastic resin composition which has far better scratch resistance, colourability, impact strength and weather resistance than thermoplastic resin compositions of the prior art while nevertheless at the same time having outstanding heat resistance. |
