Abstract
Abstract A polyacetal resin composition comprises a polyacetal resin, (A) a light stabiliser selected from the group consisting of a benzotriazole compound, a benzophenone compound, an aromatic benzoate compound, a cyanoacrylate compound, and an anilide oxalate compound and (B) an aliphatic acid ester, to give improved stability and resistance to weathering.
