Fiber-reactive dyestuffs, such as, for example, azo dyestuffs and heavy metal complex derivatives thereof, anthraquinone dyestuffs, phthalocyanine dyestuffs and formazan dyestuffs, which contain a fiber-reactive group of the vinylsulfone series and furthermore a group of the general formula ##STR1## in which R.sup.x is hydrogen or lower alkyl, which can be substituted by substituents customary in dyestuffs, and Q.sup.1 and Q.sup.2 both independently of one another are each lower alkyl, which is substituted by 1 or 2 lower alkanoyl groups or 1 or 2 lower alkoxycarbonyl groups or by one such alkoxycarbonyl and alkanoyl group, or an amino group, which is substituted by optionally substituted aryl and/or alkyl radicals, or an optionally substituted alkoxy, aryloxy, alkylthio or arylthio radical or a cyanamido radical, are described. The novel dyestuffs dye material containing hydroxy and/or carboxamide groups, such as cellulose fiber materials, wool and polyamides, in deep shades, and moreover are suitable for discharge and resist printing.
