Abstract

Water-soluble triphendioxazine compounds having fiber-reactive dye properties conforming to the general formula ##STR1## where: B is --O-- or --S-- or --NH-- or (C.sub.1 -C.sub.6)-alkylamino; PA0 R* is hydrogen or optionally substituted alkyl or aryl; PA0 W and W.sup.1 are each a bivalent, aliphatic or optionally alkyl-substituted cycloaliphatic or aliphatic-cycloaliphatic radical, which aliphatic radicals can be interrupted by --O--, --S--, sulfonyl, carbonyl, 1,4-piperidino, amino, alkylamino and/or alkanoylamino groups, or PA0 the grouping --B--W.sup.1 --N(R*) and/or --N(R*)--W--B-- each represent the bivalent radical of a five- or six-membered saturated heterocycle which contains two nitrogen atoms, or PA0 the grouping --B--W.sup.1 -- and/or --W--B-- each represent the bivalent radical of a five- or six-membered saturated heterocycle which contains two nitrogen atoms and which is bonded by one of the two nitrogen atoms via an alkylene group of 2 to 4 carbon atoms to the grouping --N(R*)--CO--G.sup.1 -- or --G--CO--A--N(R*); PA0 G and G.sup.1 are each a direct bond or a (C.sub.1 -C.sub.8)-alkylene or aliphatic-cycloaliphatic or cycloaliphatic radical; PA0 M is hydrogen, alkali m…
