HOE 89/F 098K ABSTRACT: Water-soluble fiber-reactive dyes, processes for their preparation and their use Water-soluble fiber-reactive azo, metal complex azo, anthraquinone, phthalocyanine, formazan, azomethine, dioxazine, phenazine, stilbene, triphenylmethane, xan- thene, thioxanthone, nitroaryl, naphthoquinone, pyrene- quinone or perylenetetracarbimide dyes which contain once or twice the group of the general formula Image in which: Rx and Rz are, independently of one another, hydrogen or lower alkyl, which can be substituted by halogen, hyd- roxyl, cyano, lower alkoxy, lower alkoxycarbonyl, car- boxyl, sulfamoyl, sulfo or sulfato; W is fluorine, chlorine, bromine, sulfo, phenylsulfonyl or alkylsulfonyl of 1 to 4 csrbon atoms; Y is vinyl, .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-phos- phatoethyl, .beta.-alkanoyloxyethyl of 2 to 5 carbon atoms in the alkanoyl radical, .beta.-benzoyloxyethyl, .beta.-(sulfo- benzoyloxy)ethyl, .beta.-(p-toluenesulfonyloxy)ethyl or .beta.- halogenoethyl. The fiber-reactive dyes are highly suitable for the dyeing of carboxamido-containing and/or hydroxyl-contain- ing materials, such as, for example, synthetic polyamide fiber materials, wool and in particular cellulose fiber materials with a high degree of fixation in hues which have a high color strength and good fastness properties.
