A process for the manufacture of an easily isolatable, dustless, readily dispersible pigment granulate which comprises subjecting a suspension of a finely dispersed organic pigment or pigment preparation, in the presence of water-insoluble granulating assistants belonging to the class of natural, synthetic or semi-synthetic resins, esters of dicarboxylic acids, of arylcarboxylic acids, of arylsulphonic acids, of phosphoric and phosphorous acid, phenylsulphonamides or the alkaline salts of fatty acids containing 12 to 14 carbon atoms, but in the absence of wetting agents, in a two-phase system consisting of an aqueous phase and a second liquid phase which consists substantially of an organic solvent that is virtually insoluble in water and in which the granulating assistant is at least partially soluble, to a turbulent mixing until a granulate has formed, then isolating said granulate, which consists substantially of pigment or pigment preparation, granulating assistant and organic solvent, and removing the solvent therefrom.
