Claim:
1. A thermoplastic resin composition comprising: a base resin comprising about 60 to about 90 weight % of polycarbonate resin and about 40 to about 10 weight % of polycarbonate-polysiloxane copolymer resin, each based on 100 weight of the base resin; and about 0.5 to about 2 parts by weight of luster pigment per about 100 parts by weight of the base resin, wherein the color difference (ΔE) of the thermoplastic resin composition is or below about 2.0 when irradiated by 126 MJ/m wherein the luster pigment comprises mica pearl particles coated with metal oxide, aluminum particles having a plate form and an average diameter of about 1 μm to about 100 μm, or a combination thereof, wherein the ratio of a length in a short direction to a length in a long direction of the luster pigment is about 1:5 to about 1:100, and wherein the ratio of the refractive index of the mica to the refractive index of the metal oxide is about 1:1.5 to about 1:1.9 and the ratio of the weight of pearl particles to the weight of metal oxide is about 1:0.05 to about 1:0.6.
