    Abstract: Preparation of easily dispersible pigment granules, by dispersing in an aqueous suspension of the pigment with intensive stirring a gas which does not react with the suspension in the form of fine bubbles in an essentially pressureless manner, and converting the pigment suspension thus obtained into the pigment granules by spray-drying or by mechanical removal of the liquid, shaping of the still-moist pigment cake and subsequent drying.
