Abstract:
1. A resin composition, comprising 60 to 99.9 parts by weight of a polycarbonate resin (component A) and 0.1 to 40 parts by weight of a surface-treated titanium dioxide pigment (component B), wherein component B (i) satisfies 0.15 ≦(b)−(a)≦0.3, when weight reduction at 23 to 100° C. by thermogravimetric analysis (TGA) is (a) wt % and weight reduction at 23 to 300° C. by TGA is (b) wt %, (ii) satisfies 0.003≦(d)/(c)≦0.01 and 0.005≦(e)/(c)≦0.02, when weight percentages derived from Ti, Al and Si elements in X-ray fluorescence analysis are (c) wt %, (d) wt % and (e) wt %, respectively, and (iii) has a coating of an aluminum oxide, a silicon oxide and an alkyl hydrogen siloxane in this order from the surface of the titanium dioxide made by a chlorine method.
