Abstract

Deep black thermoplastic molding compositions having high gloss can be produced by mixing the following components: 90% to 99.5% by weight of one or more styrene copolymers as component A1, or 90% to 99.5% by weight of one or more polymethylmethacrylates (PMMA) and/or polyalkylmethacrylates as component A2, or 90% to 99.5% by weight of one or more polycarbonates (PC) and/or polyester carbonates as component A3, 0.01% to 5% by weight of a pigment black as component B, 0.1% to 1.5% by weight of at least two dyes soluble in the molding composition as component C, 0% to 5% by weight of one or more additives other than components B and C, as component D. These are found to be particularly weathering-resistant.
