Abstract

Water-soluble triphendioxazine compounds which have valuable fiber-reactive dyestuff properties and correspond to the general formula (1) and dye materials, in particular cellulose fiber materials, containing carboxamide and/or hydroxy groups in fast shades. ##STR1## in which: B is a group --O--, --S--, --NH-- or --N(R')-- in which R' is alkyl having 1 to 6 carbon atoms; PA0 R* is hydrogen or optionally substituted lower alkyl or optionally substituted aryl; PA0 W and W.sup.1 independently of one another are each a divalent aliphatic radical or a cycloaliphatic radical which is optionally substituted by lower alkyl or an aliphatic-cycloaliphatic radical which is optionally substituted by lower alkyl, it being possible for the aliphatic radicals to be interrupted by one or more groups --O--, --S--, --SO.sub.2 --, --CO--, 1,4-piperidino, --NH-- and --N(R.sup.o)-- in which R.sup.o has the meaning of R' or is lower alkanoyl; PA0 the groupings --B--W.sup.1 --N(R*)-- and --N(R*)--W--B 13 independently of one another each represent the divalent radical of a five-membered or six-membered, saturated heterocyclic structure containing two N atoms, or the groupings --B--W.sup.1 -- and --W--B--…
