    摘要: High tinctorial strength, easily dispersible perylene-3,4,9,10-tetracarboximides and N,N'-dialkylperylene-3,4,9,10-tetracarboximides are produced by introducing a finely ground crude pigment whose primary particle size is not more than 0.05 micron into a primary aliphatic or aromatic amine, into a heterocyclic base, into an aliphatic carboxamide, into a mixture thereof, or into from 75 to 84% by weight sulfuric acid and converting it into pigmentary form at a temperature of from ambient temperature to 160.degree.C. The products are easily dispersible pigments of high tinctorial strength.

    摘要: 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.
