Abstract
1385938 Reactive azo dyes HOECHST AG 11 Dec 1972 [13 Dec 1971] 57138/72 New water-soluble reactive azo dyes of formula wherein A and B are aromatic-carbocyclic or -heterocyclic radicals which may be substituted, A containing at least one SO 3 H group, X is an -O-, -S-, -CO-, -SO 2 -, -CH=CH- -N=N-, -CH 2 -, -NH-, -NHCONH-, -NHCO- or -NHSO 2 - bridge member or a direct bond, w is 0 or 1 and R is an or -SO 2 CH=CH 2 group wherein Z is a radical which can be split off by means of an alkaline agent, or an OH group are prepared by azo coupling using appropriate components or, when Z in the product is OH, further reacting by esterification (e.g. sulphating or phosphating) reacting the sulphate ester with alkali to give a vinylsulphone and further reacting this with sodium thiosulphate or a dialkylamine. The dyes are used to colour wool, silk, synthetic polyamide or polyurethane fibres or leather, and in particular cellulose fibres by the usual reactive dyeing processes in greenish yellow, yellow and orange shades.
