Thermoplastic resin composition

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/m2 at a temperature of 89±3° C. and a relative humidity of 50±5% by the Xenon Arc test method according to SAE J 1885,
• 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.
