Abstract

1424331 Azo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 14 Aug 1973 [15 Aug 1972] 38007/72 Heading C4P Azo dyes, free from -SO 3 H groups, have the formula wherein A represents an aromatic carbocyclic or heterocyclic radical which carries at least one carbocyclic acid group directly attd. to an aromatic nucleus and opt. one or more other substs., R<SP>1</SP> and R<SP>2</SP> each independently represents H or an alkyl, aralkyl or aryl radical which may be opt. subs. by Cl, Br, OH, CN, alkoxy or aryloxy, X represents H, halogen, alkyl, alkoxy, aryloxy or cycloalkoxy; R<SP>3</SP> represents H or an opt. sub. alkyl or aryl radical and R<SP>4</SP> represents an acyl residue, or R<SP>3</SP> and R<SP>4</SP> are joined together to form a 5-or 6-membered heterocyclic ring. The dyes are prepared by diazotisation and coupling, and may be applied as dispersions to synthetic textile materials such as aromatic polyesters, cellulose esters, polyamides, polyurethanes, polyacrylonitrile and blends with each other or with natural fibres such as wool and cellulosic fibres.
