    Abstract: Indoaniline of the formula wherein R1 represents hydrogen, halogen, alkyl or alkoxy; R2 and R3 represent alkyl; R4, R5 and R6 each independently represent hydrogen, halogen, alkyl, alkoxy, acylamino, ureido or carbalkoxyamino and R5 can also represent amino, alkylamino, hydroxy alkylamino or carbamylalkylamino, the alkyl and alkoxy groups above being able to contain 1 to 6 carbon atoms and the acyl group from 2 to 7 carbon atoms with the condition that R5 does not represent hydrogen, chlorine, methyl or methoxy and when R5 represents acetylamino, R6 does not represent hydrogen; it being understood that the above compounds can be present in the tautomeric form of that represented by formula (I). The indoaniline is usefully employed in dye compositions for keratinic fibers, especially living human hair.

    Abstract: 1300027 Indoanilines L'OREAL 12 July 1971 [13 July 1970] 32656/71 Heading C4P The invention comprises indoaniline dyestuffs of the general formula wherein each of R 1 -R 4 are H, halogen, or C 1 -C 4 alkyl or alkoxy, and their tautomers. They are prepared by condensing 2,6-diaminopyridine with (a) p-aminophenol substituted by R 1 -R 4 in an aqueous, aqueous-alcoholic or aqueous-acetone medium at an alkaline pH in presence of an oxidizing agent at - 5 to + 40‹C, or (b) a quinonechloroimide substituted by R 1 -R 4 in an aqueous, aqueous-alcoholic or aqueous-acetone medium at an alkaline pH at 5 to 40‹C. The oxidizing agents used include hydrogen peroxide, potassium fericyanide or an ammonium or alkali metal persulphate. The amino-phenol in (a) may be used in the form of the hydrochloride, hydrobromide or sulphate. The dyes are used to dye keratinic fibres, e.g. hair in admixture with other dyes and conventional adjuvents in the form of a cream, gel, aerosol or as a wave setting lotion.
