Abstract

Water-soluble dyes having fiber-reactive properties and conforming to the general formula (1) ##STR1## where F is the radical of a metal-free or heavy metal complex monoazo or disazo dye which contains at least one sulfo group, PA0 n is 1 or 2, PA0 Y is vinyl, .beta.-sulfatoethyl, .beta.-haloethyl, .beta.-thiosulfatoethyl, .beta.-phosphatoethyl or .beta.-acetoxyethyl, PA0 R.sup..alpha. is hydrogen or lower alkyl which may be substituted by carboxy, sulfo, cyano, hydroxyl or chlorine, PA0 A is a group of the general formula (2a) or (2b) ##STR2## 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, PA1 R is hydrogen, halogen, hydroxy, sulfato, cyano, carboxy, carbamoyl, lower carbalkoxy, lower alkanoylamino, substituted or unsubstituted benzoylamino or a group of the formula --SO.sub.2 --Y.sup.2 where Y.sup.2 has one of the meanings of Y or is .beta.-hydroxyethyl, PA1 k is zero, 1 or 2, PA1 k* is zero, 1, 2, 3, or 4, PA1 X forms together with the N-atom the bivalent radical of a heterocyclic ring, PA1 Y.sup.1 has one of the meanings specified for Y, PA1 W is hydrogen, methyl, sul…
