Water-soluble dyes having fiber-reactive properties and conforming to the general formula (1) <IMAGE> (1) where F is the radical of a metal-free or heavy metal complex monoazo or disazo dye which contains at least one sulfo group, n is 1 or 2, Y is vinyl, beta -sulfatoethyl, beta -haloethyl, beta -thiosulfatoethyl, beta -phosphatoethyl or beta -acetoxyethyl, R alpha is hydrogen or lower alkyl which may be substituted by carboxy, sulfo, cyano, hydroxyl or chlorine, A is a group of the general formula (2a) or (2b) <IMAGE> (2a) <IMAGE> (2b) where G is alkylene of 1 to 6 carbon atoms, alkylene of 2 to 6 carbon atoms which is interrupted by 1 or 2 hetero groups, or methyl-substituted cycloalkylene, R is hydrogen, halogen, hydroxy, sulfato, cyano, carboxy, carbamoyl, lower carbalkoxy, lower alkanoylamino, substituted or unsubstituted benzoylamino or a group of the formula -SO2-Y2 where Y2 has one of the meanings of Y or is beta -hydroxyethyl, k is zero, 1 or 2, k* is zero, 1, 2, 3, or 4, X forms together with the N-atom the bivalent radical of a heterocyclic ring, Y1 has one of the meanings specified for Y, W is hydrogen, methyl, sulfomethyl, carboxymethyl, substituted or unsubstituted lower alkyl, substituted or methyl-substituted cycloalkylene or substituted or unsubstituted phenyl, and B has one of the meanings specified for A. The dyes of the general formula (1) make it possible to obtain strong, fast dyeings and prints on carboxamido-containing and/or hydroxy-containing materials, in particular fiber materials, such as wool, synthetic polyamide and in particular cellulose fiber materials.
