ABSTRACT:
Water-soluble monoazo compounds conforming to the general formula (1) ##STR1## where D is monosulfo- or disulfo-phenyl, which may each be substituted by lower alkyl, lower alkoxy, halogen, carboxy and/or lower alkanoylamino, or is mono- or di- or trisulfonaphthyl, K as the radical of a coupling component is para-phenylene, which may be substituted by lower alkyl, lower alkoxy, halogen, lower alkanoylamino, ureido, carbamoyl and/or sulfo, or is 1,4-naphthylene, which may be substituted by 1 or 2 sulfo groups and/or a lower alkoxy group, R is hydrogen or lower alkyl, A is phenylene or a direct bond, W is a direct bond or lower alkylene or an amino group substituted by lower alkyl, although A and W are not both a direct bond, and the group --SO.sub.2 --X is a fiber-reactive group of the vinyl sulfone series.
The azo compounds of the formula (1) are fiber-reactive and have very good dyestuff properties. They dye hydroxy- and/or carboxamido-containing material, in particular fiber material, for example cellulose fiber materials, wool and synthetic polyamide fibers, in strong, bright, fast shades. In particular they are suitable for discharge and resist printing.
