1. A thermoplastic resin composition comprising:
about 100 parts by weight of a rubber-modified aromatic vinyl copolymer resin comprising a rubber-modified vinyl graft copolymer and an aromatic vinyl copolymer resin;
about 0.1 to about 15 parts by weight of a poly(alkyl (meth)acrylate) resin having a weight average molecular weight of about 50,000 g/mol to about 130,000 g/mol and a glass transition temperature of about 90° C. to about 110° C.;
about 5 to about 20 parts by weight of a poly(ether ester amide) block copolymer; and
about 0.2 to about 5 parts by weight of sodium perchlorate (NaClO4),
wherein the thermoplastic resin composition has a haze value of about 2% to about 6% and a light transmittance of about 87% to about 96%, as measured on a 2.5 mm thick specimen in accordance with ASTM D1003.
