Thermoplastic resin composition
A thermoplastic resin composition of the present invention comprises: (A) 100 parts by weight of a thermoplastic resin comprising (A1) a rubber-modified aromatic vinyl-based graft copolymer, (A2) an aromatic vinyl-based copolymer resin having a flow index of about 5 g/10 min to about 8 g/10 min as measured by the ASTM D 1238 standard, and (A3) an α-methylstyrene copolymer; and (B) about 0.1 to about 10 parts by weight of zinc oxide, wherein the zinc oxide has a size ratio (B/A) of peak A in the region of 370 nm to 390 nm to peak B in the region of 450 nm to 600 nm of about 0.01 to about 1 in photoluminescence measurement, and has a BET surface area of about 10 m2/g or less as measured by a BET analyzer.
