Abstract
Abstract Novel dyestuffs of the formula (I) ##STR1## in which DK denotes a radical of the formula ##STR2## where m is 1 or 2 and DK' denotes a radical of the formula ##STR3## where n is 1 or 2 R 1 represents hydrogen or substituted or unsubstituted C 1 -C 4 -alkoxy, C 1 -C 4 -alkyl, R 2 represents hydrogen, substituted or unsubstituted C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy, R 3 represents substituted or unsubstituted C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or C 1 -C 4 -acylamino and R 4 represents substituted or unsubstituted C 1 -C 4 -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.
