ABSTRACT:
Water-soluble dyes are described, such as azo dyes, metal complex dyes, anthraquinone, phthalocyanine and formazan dyes, which contain a fiber-reactive group of the vinyl sulfone series which, if desired, is bound via a bridging member, and furthermore contain a 4-cyanamido-1,3,5-triazin-6-ylamino radical which is substituted in the 2 position by a group of the formula (2) ##STR1## in which R.sup.z is hydrogen or a lower alkyl group which is unsubstituted or substituted by alkyl, hydroxy, cyano, lower alkoxy, carboxyl, sulfamoyl, sulfo or sulfato or by a substituted or unsubstituted phenyl radical or is a cyclohexyl radical or a substituted or unsubstituted phenyl radical, W is an aryl, alkylenearyl, arylenealkyl, alkylenearylenealkyl or arylenealkylenearyl radical substituted by 1 to 4 water-solubilizing substituents, it being possible for these aryl, arylene, alkyl and alkylene radicals to be additionally substituted and/or interrupted by hetero groups, A is the number zero or 1, and B is the number 1 or 2, the sum of (A+B) being the number 2. The dyes are fiber-reactive and are suitable for the dyeing of hydroxy- and/or carboxamido-containing material, in particular fiber material, such as cotton, wool, silk and synthetic polyamide, by the procedures known for fiber-reactive dyes.
