ABSTRACT OF THE DISCLOSURE: Easily dispersible dust-free pigment granules of high tinctorial strength are obtained by adding to the aqueous suspension of a finely divided pigment an alkaline solu- tion of a natural or synthetic resin or of a resin mix- ture, thereafter acidifying the mixture, subjecting it to a flush process while stirring and increasing the tempera- ture above the softening point Or the resin and isolating the granules obtained. The granules are particularly sui- table for preparing printing inks, which are distinguished by a very high tinctorial strength, a good transparency and a low viscosity.
