Abstract

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 ##STR1## 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, PA1 R.sup.x is hydrogen or lower alkyl, which can be substituted by halogen, hydroxyl, cyano, lower alkoxy, lower alkoxycarbonyl, carboxyl, sulfamoyl, sulfo or sulfato; PA1 n is the number 1 or 2; and PA1 Q is a group of the formula ##STR2## in which R.sup.z 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 g…
