A pigment composition comprising A) a 1,4-diketopyrrolo¢3,4-c!pyrrole pigment of formula <IMG> (I), on the particle surface of which pigment there is adsorbed i) 0.1-10 % by weight, based on the diketopyrrolopyrrole of formula I, of a partially hydrolysed organic compound selected from the group consisting of chelates of formula <IMG> , <IMG> , (II) (III) or of esters of formula Q(OR5)4 (IV), or ii) 0.1-10 % by weight, based on the diketopyrrolopyrrole of formula I, of a diketopyrrolopyrrole of formula <IMG> (V), or iii) 0.1-10 % by weight, based on the diketopyrrolopyrrole of formula I, of a diketo- pyrrolopyrrole of formula <IMG> (VI), and 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 <IMG> (VIII), or by copolymerisation of the same monomer with a monomer which is copolymerisable with said same monomer. The symbols A, B, L, Q, R1-R18, X, Y, Z, m, n, p and q are as defined in claim 1. These pigment compositions have excellent rheology and the colorations obtained with them have surprisingly high gloss.
