Deep black thermoplastic molding compositions having high gloss and production thereof

A black thermoplastic molding composition with high gloss, consisting of:

• A) from 90 to 99.5% by weight of one or more styrene copolymers as component A1,
• B) from 0.01 to 5% by weight of a carbon black pigment as component B,
• C) as component C, from 0.5 to 1.2% by weight of at least three dyes soluble in the molding composition,
• D) as component D, from 0 to 5% by weight of one or more additional substances different from components B and C,
• where component A is a copolymer selected from the group consisting of acrylonitrile, styrene, and/or α-methylstyrene, phenylmaleimide, maleic anhydride, methyl methacrylate, and a mixture of these,
• where the ratio by weight of component B used to component C used is from 3:1 to 1:15,
• where the at least three dyes cover complementary color regions such that the combination produces a black color,
• where the thermoplastic molding compositions have a deep-black color with L*-values from 0.5 to 2.0, measured in accordance with DIN 5033:2009, and a high gloss of more than 98, measured in accordance with DIN 67530:1982, and
• where each of the percentages by weight is based on the total weight of components A to D, and these give a total of 100 percent by weight.
