Abstract

Copper complex formazan compounds which have fiber-reactive properties and are very highly suitable for use as dyes for dyeing carboxamido-containing and/or hydroxy-containing material, such as fiber material, for example wool and cellulose fiber materials, have the general formula (1) ##STR1## where A is a benzene or naphthylene ring which may be substituted by substituents customary in dyes, such as halogen, nitro, alkyl and alkoxy, PA0 B is alkylene of 1 to 8 carbon atoms or alkenylene of 2 to 8 carbon atoms which may each be substituted by phenyl which in turn may contain the substituents customary in dyes, or is alkylene-phenylene or alkenylene-phenylene having lower alkylene and alkenylene radicals, while the phenylene radicals may in turn contain the substituents customary in dyes, or is a phenylene or naphthylene radical which may contain substituents customary in dyes, or is the bivalent radical of a heterocycle, such as furan, thiophene or benzimidazole, or PA0 --B--Z together is hydrogen, PA0 Z is a water-solubilizing group, such as sulfo, PA0 k is 1 or 2, PA0 m is 0, 1 or 2, PA0 n is 0, 1 or 2, the sum (m+n) is 1 to 4; PA0 X is oxygen or carbonyloxy, PA0 R is hydrogen o…
