1. A thermoplastic resin composition comprising:

  • 100 parts by weight of (A) a thermoplastic resin comprising (A1) a rubber-modified aromatic vinyl graft copolymer, (A2) an aromatic vinyl copolymer resin having a melt index (MI) of about 5 g/10 min to about 8 g/10 min, as measured in accordance with ASTM D 1238, and (A3) an α

    -methylstyrene copolymer;

    about 0.1 parts by weight to about 10 parts by weight of (B) zinc oxide,wherein the zinc oxide has a peak intensity ratio (B/A) of about 0.01 to about 1, where A indicates a peak in the wavelength range of 370 nm to 390 nm and B indicates a peak in the wavelength range of 450 nm to 600 nm in photoluminescence measurement, and a BET surface area of about 10 m2/g or less, as measured using a BET analyzer.
