Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a thermoplastic resin containing at least one of a polyamide resin and a polyester resin; and about 1 to about 5 parts by weight of zinc oxide, wherein the zinc oxide has an average particle size (D50), measured by a particle analyzer, of about 0.8 to about 3 μm, and wherein the intensity ratio (B/A) of peak A in a region of 370-390 nm and peak B in a range of 450-600 nm, at the time of photo-luminescence measurement, is about 0.01 to about 1.0. The thermoplastic resin composition is excellent in weather resistance, antibacterial properties, mechanical properties, and the like.
