Abstract
Novel water-soluble reactive monoazo dyes of the formula I <IMAGE> in which D, as radical of the diazo component, is the radical of 1-aminobenzene-2-sulphonic acid, which may contain further substituents, such as, for example, chlorine or bromine atoms, methyl, ethyl, methoxy, ethoxy, sulphonic acid and/or acylamino groups, or the radical of 2-aminonaphthalene-1-monosulphonic acid or 2-aminonaphthalene-1,5-disulphonic acid, and Z represents one of the radicals of the formulae 2, 3 and 4 -SO2-CH=CH2 (2), -SO2-CH2-CH2-Cl (3) and -SO2-CH2-CH2-OSO3H (4), are prepared by diazotising amines of the formula D-NH2 (5), in which D has the abovementioned meaning, and coupling the resulting diazonium salt onto azo components of the formula 6 <IMAGE> in which Z has the abovementioned meaning, in a pH range of 6.5 to 8.0, preferably at pH 7.0 to 7.8. The novel dyes are suitable for dyeing and printing fibre materials, in particular wool textiles.
