Abstract:
A process for producing a solid pigment preparation in the form of granules which comprises atomizing a suspension comprising (A0) 30% to 90% of a solvent component, (A1) 2% to 60% of a pigment component; (A2) 0% to 50% of a first filler component, and (A3) 10% to 70% of a surface-active additive component based on the sum of the components (A1) and (A2); contacting formed droplets with a gas stream having a predetermined temperature to dry the droplets to obtain granules having a predetermined residual moisture content, the droplets are exposed to an aerosol comprising a solid second filler component; and separating the granules from the gas stream.
