Abstract

1424332 Sulphone azo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 19 July 1973 [15 Aug 1972] 38009/72 Heading C4P Azo dyes, which are free of sulphonic acid groups, have the formula wherein A is the residue of a diazo-component of the aromatic carbocyclic or heterocyclic series; B is a 1, 4-phenylene radical which can be substd; R<SP>1</SP> and R<SP>2</SP> are each independently H or an opt. sub. alkyl, cycloalkyl, phenyl or heterocyclic radical; and X is an alkylene radical of at least 2C, the -SO 2 XCOOH group being directly attd. to a carbon atom of an aromatic ring present in A, B, R<SP>1</SP> or R<SP>2</SP>. The dyes are prepared by diazotisation and coupling, and give yellow to navy shades with synthetic textiles such as aromatic polyesters, cellulose acetates, polyamides, polyacrylonitrile, polyurethanes, and blends of the above with each other or with natural fibres such as wool and cellulosic fibres.
