  • Patent number: 5650513
    Abstract: Reacting the industrially readily available perylene-3,4,9,10-tetracarboxylic dianhydride (3) with specific primary amines in the presence of water gives perylene-3,4-dicarboxylic bisimides (2). Their hydrolysis affords the perylene-3,4-dicarboxylic anhydride on a preparative scale, and this anhydride is reacted with any primary amines to give likewise the corresponding imides 2. Condensation of the anhydride with diamines results in novel types of dyes, namely perylene-3,4-dicarboxamidines which have very good fastness properties. Also claimed are specific perylene-3,4-dicarboxylic diesters, perylene-3,4-dicarboxylic ester amides, perylene-3,4-dicarboxamidines and perylene-3,4-dicarbonyl derivatives, processes for preparing these compounds and their use.
