HOE 88/F 004 ABSTRACT: Water-soluble azo compounds, preparation and use thereof as dyes Azo compounds which conform to the general formula (1) and are used as fiber-reactive dyes Image (1) where D is a carboxy- or sulfo-substituted phenylene or naphthylene radical, R is hydrogen or substituted or unsubstituted alkyl, M is hydrogen or a salt-forming metal, such as an alkali metal, is a group of the general formula (2) Image (2) where Y is halogen, such as fluorine or chlorine, R1 is hydrogen or substituted or unsubstituted alkyl and R2 is hydrogen or substituted or unsubstituted alkyl or a substituted or unsubstituted phenyl or naphthyl group or R1 and R2 together with the nitrogen atom form a hetero- cyclic radical. The compounds of the formula (1) are suitable for dyeing carboxamido- and/or hydroxy-containing materials, in particular fiber materials, such as wool, synthetic polyamide, in particular cellulose fibers. If applied to the materials using in particular the application and fixing methods customary for fiber-reactive dyes they produce strong fast dyeings in predominantly orange to red shades.
