Abstract (en)
[origin: WO2009019179A2] The invention relates to a method for forming (finishing) an organic pigment, the pigment being dissolved or dispersed in a mineral acid, and the pigment being allowed to crystallize out of the solution or dispersion by mixing with an aqueous diluting agent in the absence of an arylsulfonic acid condensation product having sulfonate groups and an aliphatic aldehyde as a crystallization inhibitor, characterized in that the crystallized organic pigment is allowed to mature in the presence of a surfactant or in the presence of an additive increasing the solubility of the pigment in an aqueous suspension.
