Pigment composition comprising A) a 1,4-diketopyrrolo[3,4-c]pyrrole pigment of the formula <IMAGE> on the particle surface of which are adsorbed i) 0.1-10% by weight, based on the diketopyrrolopyrrole of the formula I, of a partially hydrolysed organic compound selected from the group consisting of chelates of the formula <IMAGE> or of esters of the formula Q(OR5)4 (IV), or (ii) 0.1-10% by weight, based on the diketopyrrolopyrrole of the formula I, of a diketopyrrolopyrrole of the formula <IMAGE> or (iii)0.1-10% by weight, based on the diketopyrrolopyrrole of the formula I, of a diketopyrrolopyrrole of the formula <IMAGE> and B) 0.1-20% by weight, based on the diketopyrrolopyrrole of the formula I, of an acrylic resin which is obtainable by homopolymerisation of a monomer of the formula <IMAGE> or by copolymerisation of the same monomer with a monomer which can be copolymerised with the first monomer. For the definition of the radicals and symbols A, B, L, Q, R1-R18, X, Y, Z, m, n, p and q, reference is made to Claim 1. These pigment compositions display an outstanding rheological behaviour, while the colorations obtained with them are of surprisingly high gloss. |
