Abstract
Disclosed herein is a thermoplastic resin composition. The thermoplastic resin composition includes: a thermoplastic resin including a rubber-modified vinyl graft copolymer and an aromatic vinyl copolymer resin; a light stabilizer including a hindered amine light stabilizer (HALS) and a benzotriazole UV stabilizer; and zinc oxide having an average particle diameter of about 0.5 μm to about 3 μm and a BET specific surface area of about 1 m2/g to about 10 m2/g. The thermoplastic resin composition can have good properties in terms of weather resistance, impact resistance, appearance, and/or antibacterial properties (activity).

A thermoplastic resin composition comprising:
- a thermoplastic resin comprising a rubber-modified vinyl graft copolymer and an aromatic vinyl copolymer resin;
- a light stabilizer comprising a hindered amine light stabilizer (HALS) and a benzotriazole UV stabilizer;
- and
- zinc oxide, the zinc oxide having an average particle diameter of about 0.5 μm to about 3 μm and a BET specific surface area of about 1 m2/g to about 10 m2/g, a peak position degree (2θ) in the range of 35° to 37° and a crystallite size of about 1,000 Å to about 2,000 Å in analysis of X-ray diffraction (XRD), as calculated by Equation 1:

- where K is a shape factor, λ is an X-ray wavelength, β is an FWHM value (degree) of an X-ray diffraction peak, and θ is a peak position degree,
- wherein the thermoplastic resin composition has an out-gas emission of about 3,000 ppm or less, as measured on 3 g of a specimen after the specimen is placed on a petri dish, followed by heating to 250° C. for 2 hours.
