    • 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.
    • 通过使苝四羧酸或其官能衍生物与芳族二胺反应制备通式(Ia)或(Ib)的苝颜料或其混合物的方法,其中R 1,R 2可以相同或不同,并且可各自独立地为亚苯基, 亚萘基或亚吡啶基,其中R 1,R 2可以各自被C 1 -C 22 - 烷基,C 3 -C 22 - 烯基,C 1 -C 22 - 烷氧基,羟基和/或卤素,X 1,X 2,X 3,X 4,X 5, X 6,X 7,X 8可以相同或不同,并且各自独立地为氢或卤素,其中反应在二级或叔胺的存在下在水性反应介质中进行。
