Abstract
1285724 Reacting monoazo dyes FARBWERKE HOECHST AG 28 Aug 1969 [28 Aug 1968] 42930/69 Heading C4P Novel reactive water-soluble monoazo dyes which in the form of the free acid are of formula wherein A is a benzene or naphthalene radical, X is H or a benzene or naphthalene radical linked to A directly or via a bridge member -CO-, -SO 2 -, -CONH-, -NHCO-, -O- or -S-, B is the radical of a coupling component containing a phenolic or enolic hydroxy group or an amino group, Z is H, COOH or SO 3 H, Y is a direct link or -CH 2 -, -NH- or -N(alkyl)-, the groups -Y-SO 2 -CH 2 -CH 2 -OPO 3 H 2 and Z are linked to A, B and/or X, n is 1, 2 or 3, m is an integer from 1 to 5 and radicals A, B and X may be further substituted are prepared by azo coupling or by phosphating the dyes containing hydroxyethylsulphonyl groups. They may be used to colour leather, wool, silk, synthetic polyamides and, in particular, cellulose materials by the usual reactive dye processes in yellow, orange, red and brown shades.
