| abstract |
A thermoplastic resin composition of the present invention is characterized by comprising: about 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin; about 0.1 to about 4 parts by weight of a silver (Ag)-based compound; and about 0.7 to about 4 parts by weight of zinc oxide, wherein the zinc oxide has an average particle size (D50) of about 0.8 to about 3 ㎛, which is measured by a particle size analyzer, and wherein at the time of measurement of photo luminescence, the intensity ratio (B/A) of peak A at a region of 370 to 390 nm and peak B at a region of 450 to 600 nm is about 0.01 to about 0.1. The thermoplastic resin composition is excellent in weather resistance, antibacterial properties, mechanical properties, and the like. |
