Abstract of the Disclosure Solid preparations of organic pigments are obtained from aqueous systems which contain the pigment or in which it has been formed by adding to this system a polysaccharide having anionic groups and an affinity for this pigment, removing the treated pigment from this aqueous system and drying it. These preparations are useful for pigmenting hydrophilic media, especially aqueous or water-dilutable paints and coating agents, printing inks and printing pastes. The preparations can be prepared and processed without any great mechanical expenditure.
