    Abstract: The invention provides a non-painting and high-gloss polycarbonate resin composition. Specifically, the invention provides a polycarbonate resin composition having a superior impact strength, heat-resistance, electric characteristics, weather resistance, and light resistance. In certain embodiments, the resin composition of the invention is obtained by mixing a butadiene-based impact modifier, such as acrylonitrile-butadiene-styrene (ABS) or methacrylate-butadiene-styrene and an acryl-based impact modifier in polycarbonate resin, followed by adding an ultraviolet (UV) absorbent to the mixture.
