Abstract (en)
[origin: WO2008125628A2] The invention relates to a method for the formation of an organic pigment, wherein the pigment is dissolved or dispersed in an aqueous solvent or a mineral acid and is allowed to crystallize from the solution or dispersion in the presence of a crystallization modifier and is subsequently isolated as a solid, wherein the crystallization modifier is a condensation product of at least one hydroxyaryl sulfonic acid having sulfonate groups and/or at least one hydroxydiaryl sulfone compound and at least one aliphatic aldehyde with 1-6 carbon atoms, optionally containing urea and possibly an alkali sulfite, or a mixture of such condensation products.
