ABSTRACT:
The present disclosure relates to a resin composition having excellent thermal stability, light reflectivity and color, and, preferably, flame retardancy. The present disclosure also relates to 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), wherein component B (i) satisfies 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) satisfies 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.
