HOE 89/F 142 K ABSTRACT: Water-soluble azo dyes, processes for their preparation and their use Water-soluble azo dyes and their heavy metal complex derivatives, such as copper, cobalt and chromium complex azo dyes are described, which have the general formula (1) shown below, have fiber-reactive properties and dye natural and synthetic hydroxyl- and/or carboxamido- containing materials, in particular fiber materials, such as wool and in particular cellulose fiber materials, by the dyeing and printing processes customary for fiber- reactive dyes, in hues which have high color strength and good fastness properties. Image (1) in which the symbols have the following meanings: F is the radical of a monoazo, disazo or polyazo dye or a heavy metal complex azo dye; R is hydrogen or alkyl of 1 to 4 carbon atoms, which can be substituted by halogen, hydroxyl, cyano, alkoxy of 1 to 4 carbon atoms, alkoxycarbonyl of 2 to 5 carbon atoms, carboxyl, sulfamoyl, sulfo or sulfato; X is chlorine, bromine, sulfo, alkylsulfonyl of 1 to 4 carbon atoms or phenylsulfonyl; Y is vinyl, .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.- phosphatoethyl, .beta.-alkanoyloxyethyl of 2 to 5 carbon atoms in the alkanoyl radical, .beta.-benzoyloxyethyl, .beta.- (sulfobenzoyloxy)ethyl, .beta.-(p-toluenesulfonyloxy)- ethyl or .beta.-halogenoethyl; p is the number 1 or 2; n is the number 1 or 2.
