PROBLEM TO BE SOLVED: To provide a polyacetal resin coloring composition having improved thermal stability during kneading or molding, particularly less generation of formaldehyde odor, and improved generation of adhesion to a mold. SOLUTION: (B) 0.1 to 30 parts by weight of carbon black in which (B) an ethylene-based polymer compound of 0.3 to 8 times by weight of carbon black is previously integrated with 100 parts by weight of polyacetal resin. Parts by weight, A polyacetal resin coloring composition comprising (C) 0.01 to 5 parts by weight of an amine antioxidant and (D) 0.1 to 10 parts by weight of a nitrogen-containing compound. |
