P-18635/A Novel pigment compositions Pigment compositions comprising a) at least one organic pigment, b) 0.05 to 10 % by weight, based on the organic pigment a), of at least one modified organic pigment of formula A?(SO3X)m (I), wherein A is the radical of an organic pigment, X is H, Na or K and m is an integer from 0.05 to 3, and c) 0.05 to 10 % by weight, based on the organic pigment a), of at least one polymeric ammonium salt having an average molecular weight from 500 to 2500 000 and which is soluble in water or a lower alkanol. These pigment compositions have excellent suitability for the warp-free pigmenting of polyolefins and, when incorporated in paint systems and printing inks, exhibit excellent rheology.
