Abstract
The invention relates to a method for producing vattable organic pigments. The invention is characterized in that an agueous or an aqueous-organic suspension of a coarse crystalline raw mineral is vatted and re-oxidised, and the pigment suspension is ground to a diameter equal to or less than 0.9 mm during vatting and/or during oxidation by means of an agitator ball mill, which is operated at a power density of more than 1.0 KW per litre per grinding chamber and at an agitator peripheral speed of more than 12 m/s, using grinding bodies.
