Abstract

Perylene derivatives of the general formula I whereX and Y are independently oxygen, —NR1 or —NR2;R1 and R2 are independently hydrogen, C1-C18-alkyl, C5-C7-cycloalkyl, aryl or C1-C6-alkoxy;R3 to R10 are independently hydrogen, hydroxyl or aryl, although radicals conjointly attached to one carbon atom may also be ═O or ═CHR11,R11 is hydrogen or C1-C3-alkyl,with the proviso that said perylene derivative I contains from at least one to not more than three carbonyl groups per molecule.
