Abstract
Abstract An acetal resin composition comprising (A) 100 parts of an acetal resin, (B) 0.01 to 2 parts by weight of a higher fatty acid ester derived from a polyhydric alcohol having 2 to 10 carbon atoms as an alcohol component and a higher fatty acid having 22 to 32 carbon atoms as an acid component and, optionally, (C) 0.01 to 2 parts by weight of a linear fatty acid having at least 10 carbon atoms.
