Abstract
1357700 Azo dyes containing sulphonamide groups FARBWERKE HOECHST AG 17 Feb 1972 [18 Feb 1971] 7399/72 Heading C4P Novel water-insoluble dyestuffs of the formula (wherein D is the radical of a diazo component of the benzene, azobenzene or heterocyclic series, K is a radical of the benzene or naphthalene series containing the azo group and the substituted amino group in para position to each other, and D and K may be substituted by non- water-solubilizing groups, R 1 is H or C 1-4 alkyl which may be substituted by non-water-solubilizing groups, n is 1, 2 or 3 and R 2 and R 3 are each H or C 1-4 alkyl) are prepared by coupling diazotized amines D-NH 2 with appropriate coupling components. The dyestuffs are used for the dyeing and printing of synthetic fibres.
