Claim:
A polyacetal resin composition, comprising: (A) 100 parts by weight of a polyacetal copolymer containing 1.0 mmol/kg or smaller or a hemiformal terminal group, 2.0 mmol/kg or smaller of a formyl terminal group, 0.5 wt % or smaller of an unstable terminal group, (B) 0.03 to 0.30 part by weight of a hindered phenol-based antioxidant, (C) 0.01 to 1 part by weight of a guanamine compound, (D) 0.2 to 1 part by weight of a hindered amine-based stabilizer, (E) 0.1 to 1 part by weight of a UV absorber, and (F) 3 to 10 parts by weight of a metallic pigment, wherein the composition exhibits a reduced formaldehyde emission of 3.5 μg/g and below, and improved weatherability after exposure to light of 330 hours at a wavelength of 320 nm and an intensity of 162 w/m 2 of 100% gloss retention and a change in hue (ΔE) of 0.7 or less.
