Abstract

1435516 Water-insoluble azo dyestuffs containing carboxylic acid groups IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Aug 1973 [12 Sept 1972] 42224/72 Heading C4P Novel water-insoluble azo dyestuffs, free from sulphonic acid groups, have the formula wherein R is H or an optionally substituted alkyl, cycloalkyl, aryl or heterocyclic radical, and the X and Y rings can contain further substituents, provided that the dyestuffs contain at least one carboxylic acid group in X, Y or R. They are prepared by coupling a diazotized aniline with an appropriate homophthalimide and are valuable for colouring synthetic textile materials, e.g. of aromatic polyesters, polyamides and cellulose acetates.
