The water-soluble azo compounds have fiber-reactive dye properties and dye carboxamide and/or hydroxyl group-containing materials, such as, for example, wool, synthetic nylon fibers and, in particular, cellulose fibers, in fast shades. in which R, M and n have one of the meanings mentioned in claims 14 and the two primary amino groups are bound in the meta- or para-position to one another on the benzene ring, reducing the nitro group in the resultant compound, and reacting in said resultant compound the both primary amino groups with a diazotizing agent to give the diazonium compound, and, if desired, converting the beta -hydroxyethyl group standing for the moiety Y', into another Y' group.

    Abstract: Water-soluble dyes which contain one or two fibre-reactive groups of the formula in which each R" denotes a hydrogen atom or an alkyl group of 1 to 4 C atoms, where both R" can have an identical or different meaning to one another, R denotes a hydrogen atom or a sulpho group and Y is the vinyl group or a beta -sulphatoethyl group.
