    摘要: A process for preparing perylene pigments of the general formula (Ia) or (Ib) or mixtures thereof, by reacting perylenetetracarboxylic acids or functional derivatives thereof with aromatic diamines, where R1, R2 may be the same or different and may each independently be phenylene, naphthylene or pyridylene, where R1, R2 may each be mono- or polysubstituted by C1-C22-alkyl, C3-C22-alkenyl, C1-C22-alkoxy, hydroxyl and/or halogen, X1, X2, X3, X4, X5, X6, X7, X8 may be the same or different and may each independently be hydrogen or halogen, wherein the reaction is performed in the presence of a secondary or tertiary amine in an aqueous reaction medium.

    摘要: A process for preparing colorants of the general formula (Ia), (Ib) or (Ic) or mixtures thereof, comprises reacting (a) tetracarboxylic acids or their functional derivatives with (b) at least one compound selected from i. aliphatic amines, ii. aromatic amines, iii. aliphatic diamines, iv. aromatic diamines, (c) optionally in the presence of further additives, (d) optionally in the presence of wetting agents in a mixing apparatus. These colorants are useful for coloration of macromolecular organic and inorganic materials of natural and synthetic origin.
