ABSTRACT:
The present invention relates to surface-treated organic pigments, to a process for their preparation and to their use in colouring a high molecular weight organic material. Compared with untreated pigments, the surface-treated pigments exhibit better rheological properties and/or no warping in the pigmenting of partially crystalline plastics.
