Abstract
These dyestuffs are water soluble, devoid of sulphonic acid and carboxylic acid groups and have the formula: <IMAGE> wherein D is a carbocyclic or heterocyclic radical containing at least one electron-withdrawing group, preferably in the ortho position and more preferably nitro, X is an optionally substituted alkoxy or alkylcarbonyl group, the ring E may also optionally be substituted with lower alkyl or halogen, R<1> and R<2> are selected from hydrogen, optionally substituted lower alkyl, cycloalkyl, aralkyl and aryl or R<1> and R<2> together with the nitrogen atom form a 5 or 6 membered ring which may contain additional hetero atoms and A is an anion. The group X stabilises the coloured azonium tautomer in preference to the colourless ammonium tautomer giving valuable dyes for polymeric, especially polyacrylonitrile, materials.
