HOE 88/F 005 Water-soluble 2-naphthol azo compounds, preparation and use thereof as dyes Monoazo compounds which conform to the general formula (1) given below and are used as fiber-reactive dyes for dyeing carboxamido-containing and/or hydroxy-containing materials, for example wool, synthetic polyamide fibers and in particular cellulose fibers, in fast, predominantly yellowish red, red and orange shades. (1) where M is a hydrogen atom or an alkali metal or a divalent metal, D is an unsubstituted or carboxy- and/or sulfo substituted phenylene or naphthylene radical, the group X-N(R)- is a fiber-reactive group in which R is hydrogen or substituted or unsubstituted alkyl and X denotes a group of the formula (2) (2) where Y is halogen, R* is hydrogen or substituted or unsubstituted alkyl, A is a direct bond or an ethyleneamino- or sulfo- or carboxy -substituted phenylamino or A lower alkylene group and W denotes a phenyl or naphthyl radical which in either case is substituted by a fiberreactive group of the vinyl sulfone series and which in the case of naphthyl can be substituted by 1 or 2 sulfo groups and in the case of phenyl in addition by substituents selected inter alia from the group consisting of alkyl, alkoxy, chlorine, sulfo, carboxy , nitro and alkylamino. |
