摘要

Novel dyestuffs of the formula (I) (I) +TR in which DK denotes a radical of the formula where m is 1 or 2 and DK' denotes a radical of the formula where n is 1 or 2 R1 represents hydrogen or substituted or unsubstituted C1-C4-alkoxy, C1-C4-alkyl, R2 represents hydrogen, substituted or unsubstituted C1-C4-alkyl or C1-C4-alkoxy, R3 represents substituted or unsubstituted C1-C4-alkyl, C1-C4-alkoxy or C1-C4-acylamino and R4 represents substituted or unsubstituted C1-C4-alkyl. have now been found. The invention also relates to a process for their preparation and to their use for dyeing/coloring and printing textiles and paper, in particular in printing inks containing these dyestuffs.
