ABSTRACT:
The invention relates to a pigment preparation based on at least one inorganic pigment and at least one organic pigment, and to a method for producing one such pigment preparation. Said pigment preparation contains particles wherein fine organic pigment particles are combined with inorganic pigment particles, said particles also being provided with an organic macromolecular coating. The inventive pigment preparation is produced by wet-grinding the inorganic and organic pigments, optionally adding other constituents, in the presence of a surface-active substance in the form of a macromolecular organic compound.
