A pigment composition comprising n A) a 1,4-diketopyrrolo 3,4-c!pyrrole pigment of formula ##STR1## wherein A and B are each independently of the other a group of formula ##STR2## wherein R 1 and R 2 are each independently of the other hydrogen, halogen or CN, and n B) 0.1-20% by weight, based on the diketopyrrolopyrrole of formula I, of an acrylic resin obtainable by homopolymerisation of a monomer of formula ##STR3## wherein R 3 is hydrogen or methyl and R 4 and R 5 are each independently of the other hydrogen, methyl or ethyl, and n is an integer from 1 to 6, or by copolymerisation of the same monomer with a monomer which is copolymerisable with said same monomer, wherein the homopolymerization or copolymerization is carded out in the absence of a nonionic active agent n These pigment compositions have excellent rheology and the colorations obtained with them have surprisisingly high gloss. |
