There is provided a resin composition that is excellent in thermal stability, light reflectivity and color, and preferably in flame retardancy.
There is also provided a method for producing a resin composition which comprises mixing 60 to 99.9 parts by weight of polycarbonate resin (component A) with 0.1 to 40 parts by weight of titanium dioxide pigment (component B), the component B
(i) satisfying 0.05≦(b)−(a)≦0.6, 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 %, and
(ii) satisfying 0.001≦(d)/(c)≦0.01 and 0.001≦(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.
