The present invention relates to a polyoxymethylene molding composition comprising n (A) 0.1-5.0% by weight of colorant, n (B) 0.01-0.5% by weight of a nitrogen-containing stabilizer, n (C) 0.05-1% by weight of an ester of a polyhydric alcohol and at least one fatty acid, and n (D) 0.001-0.5% by weight of a metal salt of a fatty acid, and n (I) polyoxymethylene polymer and, where appropriate, up to 40% by weight of other conventional additives, and variants of this constitution in advantageous versions. n In the case of these polyoxymethylene molding compositions the selection of the colorants is no longer restricted to conventional colorants suitable particularly for POM. n The products produced therewith are particularly stable during processing and feature low formaldehyde emission, defect-free surfaces, and high color fastness. |
