Abstract

Water-soluble azo compounds corresponding to the general formula D--N.dbd.N--K which have advantageous fiber-reactive dyestuff properties and dye materials containing carboxamide groups and in particular materials containing hydroxy groups, such as wool and in particular cellulose fiber materials, in deep fast shades are described. In the formula D--N.dbd.N--K: PA0 D is a radical of the general formula ##STR1## in which Y is the vinyl group or an ethyl group in the .beta.-position which can be removed by an alkaline radical, R is hydrogen, nitro, lower alkyl, lower alkoxy, carboxy or hydroxy or halogen, M is hydrogen or a salt-forming metal atom and n is the number zero or 1; and PA0 K is a radical of a water-soluble coupling component which can be coupled in one position and can also contain an azo group, or the radical of a water-soluble coupling component which can be coupled in two positions, in each case from the series comprising aminobenzenes, phenols, naphthols, aminonaphthols, acylamino-napthols, dihydroxynaphthalenesulfonic acids, phenylazo-aminonaphtholsulfonic acids, naphthylazo-aminoaphtholsulfonic acids, 5-pyrazolones, 5-aminopyrazoles, acetoacetyl arylides, 2-hydroxy…
