Aryl-pararosaniline sulfonic acid pigments can be transformed into a pigment preparation having high tinctorial strength and being easily dispersible by dissolving them in aqueous alkali, adding a water-soluble synthetic resin (being a reaction product or mixture of (I) maleic anhydride addition product of an unsaturated fatty acid or fatty acid polyol ester, said addition product being partially esterified with a polyol, and (II) a low-molecular curable and partially etherified aminoplast and optionally an anionic or nonionic surfactant and precipitating the preparation with a mineral acid. These preparations are especially useful for pigmenting printing inks, carbon paper, duplicating papers and typewriter ribbons.
