PCT No. PCT/EP90/00715 Sec. 371 Date Jan. 10, 1992 Sec. 102(e) Date Jan. 10, 1992 PCT Filed May 4, 1990 PCT Pub. No. WO90/13604 PCT Pub. Date Nov. 15, 1990.Water-soluble dyestuffs which correspond to the formula (1) given below, have fiber-reactive properties and dye synthetic and natural materials, in particular fiber materials, containing hydroxyl and/or carboxamide groups, such as wool and in particular cellulose fiber materials, in deep shades (1) in which: F is the radical of a dyestuff, such as of an azo dyestuff, heavy metal complex azo dyestuff, anthraquinone dyestuff or phthalocyanine dyestuff, Rx is hydrogen or lower alkyl, which can be substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato; n is the number 1 or 2; and Q is a group of the formula (2a) or (2b) in which Rz is hydrogen or lower alkyl, which can be substituted by halogen, hydroxyl, cyano, lower alkoxy, carboxyl, sulfamoyl, sulfo, sulfato or by optionally substituted phenyl, or is cyclohexyl or optionally substituted phenyl, W is optionally substituted arylene or a combined radical of alkylene and arylene, in which the alkylene radicals and arylene radicals can be substituted and the alkylene radicals and alkylene-arylene radicals can likewise be interrupted by hetero groups; the group -SO2-Y is a fiber-reactive group from the vinylsulfone series, z is the number 1 or 2, A is the number zero or 1, B is the number 1 or 2, the sum of (A+B) being 2, X, together with the N atom and 1 or 2 lower alkylene groups and if appropriate 1 or 2 hetero groups, forms the radical of a heterocyclic ring and alk is a lower alkylene, are described.
