Abstract:
1. A polyamide resin composition comprising (A) polyamide resin, (B) about 0.1 to about 50 parts by weight of white pigment, and (C) about 0.01 to about 20 parts by weight of sodium phosphate salt, each based on about 100 parts by weight of polyamide resin (A), wherein the polyamide resin composition has an initial light reflectivity measured by colorimeter at a wavelength of 440 nm of more than about 90, a light reflectance reduction measured at a wavelength of 440 nm after a specimen is illuminated by a LED light source for 144 hours under a temperature of 85° C. and relative humidity of 85% of less than about 5, and a change of yellow index (ΔYI) measured after a specimen is illuminated by a LED light source for 144 hours under a temperature of 85° C. and relative humidity of 85% of less than about 3.
