ABSTRACT:
Derivatives of 9-oxo-1,9a,10-triaza-9-hydroanthracene of the general formula I ##STR1## with the exception of three compounds in which R denotes a hydrogen atom, halogen atom, an alkyl-C.sub.1 -C.sub.4, alkoxy-C.sub.1 -C.sub.4 or denotes a trihalogenomethyl group, a --CO--NH.sub.2, --CO--NH--(alkyl-C.sub.1 -C.sub.4) or --CO--N(alkyl-C.sub.1 -C.sub.4).sub.2 group or phenyl, alkyl-C.sub.1 -C.sub.4, --NH.sub.2, --NH(alkyl-C.sub.1 -C.sub.4), --N(alkyl-C.sub.1 -C.sub.4).sub.2 or an alkylene-C.sub.1 -C.sub.4 --OSO.sub.3 H group, bound via the bridge member --S--, --SO--or --SO.sub.2 --, a or a fused-on 4- to 7-membered isocycle or heterocycle, which itself can be part of a polycyclic system, from the series consisting of naphthalene, acenaphthene, phenanthrene and indole, x denotes an integer from 1 to 4, where for x>1 R can be identical or different, and z denotes a fused-on 4- to 7-membered isocycle or heterocycle, which itself can be part of a polycyclic system, from the series consisting of naphthalene, acenaphthene, phenanthrene and indole, in which each of the 4- to 7-membered isocycles or heterocycles and each of the polycyclic systems mentioned can be substituted, processes for their preparation and their use for the coloring of natural or synthetic materials.
