    摘要: Organic pigments which provide an opaque color impression in binders and exhibit adequate flow properties in binders are obtained from pigments which provide a transparent color impression in binders in a simple way in that an azeotrope-forming agent which is appropriate for the liquid adhering to the pigment is added to the moist pigment obtained after the preparation, and the azeotropic mixture and any excess solvent which may be present are then distilled off.
