<p>In a process for producing a solid pigment preparation in the form of granules which comprises the steps of (a) atomizing a suspension comprising (A0) 30% to 90% by weight of a solvent component based on the overall weight of the suspension; (A1) 2% to 60% by weight of a pigment component based on the overall weight of the suspension; (A2) 0% to 50% by weight of a first filler component based on the overall weight of the suspension, (A3) 10% to 70% by weight of a surface-active additive component based on the sum total of the weights of said components (A1) and (A2), and optionally further components, the sum total of the weight fractions of all components, based on the overall weight, being 100% by weight, in an atomizing apparatus; (b) contacting the droplets formed in step (a) with a gas stream having a predetermined temperature to dry the droplets to obtain granules having a predetermined residual moisture content, and (c) separating the granules from the gas stream, in step (b), before reaching the residual moisture content, the droplets are at least partly exposed to an aerosol comprising a solid second filler component.</p> |
