ABSTRACT:
Indoaniline of the formula ##SPC1## wherein R.sub.1 represents hydrogen, halogen, alkyl or alkoxy; R.sub.2 and R.sub.3 represent alkyl; R.sub.4, R.sub.5 and R.sub.6 each independently represent hydrogen, halogen, alkyl, alkoxy, acylamino, ureido or carbalkoxyamino and R.sub.5 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 R.sub.5 does not represent hydrogen, chlorine, methyl or methoxy and when R.sub.5 represents acetylamino, R.sub.6 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.
