Water-soluble triphendioxazine compounds of the formula <IMAGE> (1) having at least one sulfato or sulfo group, in which R is a hydrogen atom, a water-solubilizing group, an alkyl group having 1 to 6 carbon atoms which is substituted by an acidic group, or an optionally substituted sulfonamide group, B is an oxygen or sulfur atom or a group of the formula -NH-or -N(R')-, where R' equals optionally substituted alkyl, cycloalkyl which is optionally substituted by certain substituents, or optionally substituted phenyl, or naphthyl which is optionally substituted by sulfo and/or a -SO2-Y' group, B1 has one of the meanings stated for B and is identical to B or different from B, W is a bivalent aliphatic, araliphatic or aromatic radical which may be interrupted by 1 or 2 hetero groups from the series comprising groups of the formulae -O-, -NH-and -N(R')-, where R' has the above meaning, W1 has one of the meanings stated for W and is identical to W or different from W, T is a hydrogen atom or sulfo, sulfato, phosphato or carboxy, T1 has one of the meanings stated for T and is identical to T or different from T and T1 is necessarily a water-solubilizing group when R denotes hydrogen, R3 R4, identical or different, are each hydrogen, alkyl, alkoxy, halogen, carboxy or sulfo, X1 is hydrogen, halogen, cycloalkyl, arylkyloxy, alkoxy, aryloxy, alkyl, aryl, aralkyl, cyano, carboxyl, carbalkoxy, N-alkyl-substituted carbamoyl or N-aryl-substituted carbamoyl, alkanoylamino or optionally substituted aroylamino, X2 has one of the meanings stated for X1 and is identical to X1 or different from X1, Y is vinyl or ethyl which is substituted in the beta position by a substituent which can be eliminated by means of an alkali, Y' has one of the meanings stated for Y and is identical to Y or different from Y. These new compounds have fiber-reactive dyestuff properties and are particularly suitable for dyeing cellulose fiber materials so that they are fast.
