    Abstract: Production of pigmented resin powders by finely dispersing dispersions of pigments in solutions of polymeric materials in at least one organic solvent in water containing a protective colloid while supplying mixing energy, and removing the solvent. A preferred method is to introduce one or more jets of water containing protective colloid at the rate of 5 to 100 m/sec into animpulse exchange chamber together with the dispersion issuing in the immediate vicinity of the orifice(s), and to remove the solvent. The method avoids crosslinking and provides pigmented resin powders of consistently reproducible color which are suitable for conventional powdered-resin coating methods.

    Abstract: A process for the manufacture of deep-shade perylene-3,4,9,10tetracarboxylic acid dianhydride pigments, wherein finely ground crude pigment of which the average primary particle size is from 0.01 to 1 Mu is treated with a primary or tertiary aromatic amine which is liquid at the treatment temperature, or with a strongly polar aprotic solvent, as swelling agent, until the pigment has acquired the optimum color strength. After removal of the swelling agent, a deep-shade, pure pigment is obtained, which is suitable for all pigmentation purposes.
