Abstract:
1. A polyacetal resin composition comprising: (A) 100 parts by weight of a polyacetal resin, (B) 0.01 to 5 parts by weight of a colorant selected from inorganic and organic pigments, (C) 0.01 to 3 parts by weight of (C1) below, or 0.01 to 3 parts by weight of (C2) below, (D) 0.01 to 1 part by weight of a dihydrazide compound selected from the group consisting of aromatic dihydrazide compounds, and aliphatic dihydrazide compounds having a solubility of less than 1 g relative to 100 g of water at 20° C., and (E) 0.01 to 1 part by weight of (E1) below, or a combination of 0.01 to 5 parts by weight of (E2) below and 0.01 to 5 parts by weight of (E3) below, wherein X represents an organic group having a carbon atom at the bonding portion with the nitrogen atom, and Y represents an organic group that is bonded with a piperidyl group via an oxygen atom or a nitrogen atom, or a hydrogen atom; wherein the polyamide resin (C1) is dimer acid polyamide resin; and wherein the amide portion of the polyetheresteramide resin (C2) is dimer acid polyamide resin.
