Abstract
1306645 Reactive water-soluble monoazo dyes FARBWERKE HOECHST AG 19 April 1971 [14 March 1970] 23914/71 Heading C4P New water-soluble monoazo dyes of formula wherein n is 0 or 1, R is a C 1-4 alkyl or alkoxy group, R<SP>1</SP> is H or a C 1-4 alkyl or alkoxy group, R<SP>11</SP> is H or an alkyl group, Z is a carboxylic or sulphonic acid acyl radical and X is a group wherein Y is -OH or a radical capable of being split off by an alkali, are prepared by azo coupling using appropriate components, followed by further reactions to modify the sulphone group if desired. In examples dyes wherein Y is -OH, -O.SO 3 H, -N(C 2 H 5 ) 2 , are described. The dyes are preferably used to colour cellulose fibres by the usual reactive dyeing processes in orange and red shades.
