Pigment compositions comprising an organic pigment whose particle surface is provided with a protective coating layer, which coating comprises (a) a metal phosphate complex in which the metal is selected from the group consisting of, zirconium, titanium and mixtures thereof in a quantity of from 0.5 to 100 % by weight, preferably to 20% by weight, particularly preferably from 1 to 10% by weight, based on the pigment; and (b) an amine or ammonium salt, in a quantity of from 0.5 to 15% by weight, preferably up to 10% by weight, particularly preferably up to 5% by weight, based on the pigment. The compositions are distinguished by outstanding properties, especially by the high gloss of the colourations obtained therewith, by very good dispersibility, high dispersion stability and heat resistance and by very good rheological characteristics of the paint millbases or printing inks prepared therewith. The plastics pigmented with the compositions of the invention are likewise distinguished by good dispersibility.
