Abstract: The present invention refers to a polyamide moulding composition consisting of the following components: (A) 30 to 79.7% by weight of at least one partially crystalline polyamide consisting of at least one diamine and at least one aromatic dicarboxylic acid, whereupon the at least one diamine has 4 to 20 carbon atoms and is selected from a group of diamines consisting of linear aliphatic diamines, branched aliphatic diamines, cycloaliphatic diamines and araliphatic diamines, (B) 0 to 10% by weight of at least one polyamide different from component (A) (C) 20 to 55% by weight of at least one fibrous reinforcing agent, (D) 0.2 to 2.0% by weight of nigrosine, (E) 0.1 to 3.0% by weight of at least one heat stabilizer, (F) 0 to 10% by weight of a at least one additive, whereby the entirety of components (A) to (F) add up to 100% by weight.
