The invention relates to pigment concentrates for coloring thermoplastics, comprising - at least one color pigment - at least one copolymer wax, produced by converting long-chain olefin hydrocarbon in the chain length range of = 12 C-atoms having unsaturated polycarboxylic acids or anhydrides thereof in the presence of at least one radical starter and comprising a) 40 - 60 mol-% units derived from a-olefins of the chain length C12-C60, preferably C24-C60, particularly preferably C28-C60, and b) 60-40 mol-% units that derive from unsaturated polycarboxylic acids or anhydrides thereof, and at least one thermoplastic polyolefin as applicable. |
