Abstract
A thermoplastic resin composition of the present invention comprises approximately 100 parts by weight of a rubber-modified aromatic vinyl-based copolymer resin, approximately 50-150 parts by weight of a polyalkyl (meth)acrylate resin, approximately 0.1-3 parts by weight of a silver (Ag)-based compound; and approximately 0.5-10 parts by weight of zinc oxide, wherein the zinc oxide is composed of primary particles and secondary particles, the average particle size (D50) of the primary particles, measured by means of a particle size analyzer, is approximately 1-50 nm, and the average particle size (D50) of the secondary particles is approximately 0.1-10 μm. The thermoplastic resin composition has excellent antibacterial property, thermal stability, transparency, metal texture and the like.
