Abstract

1386165 Monoazo dyes HOECHST AG 24 May 1972 [26 May 1971] 24495/72 Heading C4P New monoazo dyes of formula wherein A and A<SP>1</SP> are radicals of the benzene series, Z 1 is a bivalent bridging member, X is a group bound to A and/or A<SP>1</SP> of formula -SO 2 CH 2 CH 2 Z or -SO 2 CH=CH 2 wherein Z is a radical capable of being split off by an alkaline agent, or OH, m is 0 or 1 and n is 1 or 2 are prepared by coupling a diazo compound of an amine H 2 N-[-A-(Z 1 -A<SP>1</SP>) m -]-(X) n with 2 - naphthol - 8 - sulphonic acid and when Z is OH converting this to an -O.SO 3 H or group by reaction with a sulphating or phosphating agent. The dyes are used to colour leather and fibrous materials of silk, wool, synthetic polyamides and polyurethanes and in particular cellulose fibres in the presence of alkali in yellow to red shades.
