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. The compounds according to the invention are suitable, for example, as colorants for the mass coloration of high-molecular-weight organic material, for use in security printing, as fluorescent dyes for machine-readable markings, as laser dyes, and for preparing non-impact printing toners, color filters, organic photoreceptors, electroluminescence and photoluminescence elements or sun collectors and in specific substituted compounds are also suitable for use as rheology improvers.
利用工业上易得的苝并三酐-3,4,9,10-四羧酸二酐(3)与特定的一级胺在水存在下反应,可以得到苝并-3,4-二羧酸双咪唑(2)。它们的水解在制备规模上得到苝并-3,4-二羧酸酐,而这种酐与任何一级胺反应同样可以得到相应的咪唑2。酐与二胺的缩合反应产生了新型染料,即苝并-3,4-二羧酰胺,其具有非常好的牢度性能。还声明了特定的苝并-3,4-二羧酸二酯,苝并-3,4-二羧酸酯酰胺,苝并-3,4-二羧酰胺和苝并-3,4-二羰基衍生物,以及制备这些化合物和它们的用途的方法。本发明的化合物适用于高分子有机材料的质量着色剂、安全印刷、机读标记的荧光染料、激光染料、制备非冲击式印刷调色剂、彩色滤光片、有机光感受器、电致发光和光致发光元件或太阳能收集器,而特定的取代化合物也适用于作为流变改进剂。
