ABSTRACT:
The present invention relates to a method of producing a low-dust pigment composition, which comprises suspending a filter cake obtained from preparation of the pigment, or a solid pigment, in water, adding thereto from 0.1 to 6.0% by weight, based On the weight of the pigment composition, of an amphoteric surfactant and, where appropriate, further adjuvants, and then drying the aqueous suspension to form granules, to the pigment composition obtainable according to that method, and to the use thereof in the production of colored plastics or colored polymeric particles.
