Abstract
1389550 Reactive azo dyes HOECHST AG 11 Dec 1972 [11 Dec 1971] 57139/72 Heading C4P New water-soluble reactive azo dyes of formula wherein R is H or an optionally substituted alkyl, cycloalkyl or aralkyl group, A, D and E are each an optionally substituted benzene, naphthalene or heterocyclic radical, B is an optionally substituted benzene, naphthalene, aliphatic or cycloaliphatic group, G is an optionally substituted benzene or naphthalene radical, Z is a fibre-reactive group, Y is -O-, -S-, -CO-, -SO 2 -, -CH=CH-, -NHCONH-, -NHCH 2 -, -NHCO- or -NHSO 2 -, n is 0 or 1, m is 1 or 2, v and w are each 0 or 1, a and b are each 0 or 1 and E and D contain at least one acidic water-solubilizing group are described. They are prepared by azo coupling or by condensation reactions which introduce or modify the fibre-reactive group. The dyes are used to colour leather or natural or regenerated cellulose, regenerated protein, wool, silk, synthetic polyamide or polyurethane fibres by the usual reactive dyeing processes in yellow to red shades.
