SUBSTITUTED POLYCYLIC DERIVATIVES OF THE 9-OXO-1,9A,10-TRIAZA-9-HYDROANTHRACENE AND METHOD FOR COLORING OF NATIVE OR SYNTHETIC MATERIALS

Derivatives of 9-oxo-1,9a,10-triaza-9-hydroanthracene of the general formula I (I) with the exception of three compounds in which R denotes a hydrogen atom, halogen atom, an alkyl-C1-C4, alkoxy-C1-C4 or denotes a trihalogenomethyl group, a -CO-NH2, -CO-NH-(alkyl-C1-C4) or -CO-N(alkyl-C1-C4)2 group or phenyl, alkyl-C1-C4, -NH2, -NH(alkyl-C1-C4), -N(alkyl-C1-C4)2 or an alkylene-C1-C4-OSO3H group, bound via the bridge member -S-, -SO-or -SO2-, 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.
