Abstract

Abstract Indoaniline of the formula <IMAGE> wherein R1 represents hydrogen, halogen, alkyl or alkoxy; R2 represents alkyl, hydroxyalkyl, carbamylalkyl, piperidinoalkyl, morpholinoalkyl, sulfoalkyl, dialkylaminoalkyl, acylaminoalkyl, (preferably acetylaminoalkyl or benzoylaminoalkyl) and mesylaminoalkyl; R3 represents hydroxyalkyl, carbamylalkyl, piperidinoalkyl, morpholinoalkyl, sulfoalkyl, dialkylaminoalkyl, acylaminoalkyl, (preferably acetylaminoalkyl or benzoylaminoalkyl), mesylaminoalkyl; or R2 and R3 together form with the nitrogen atom to which they are attached a heterocycle selected from piperidino or morpholino; R4, R5 and R6 each independently represents hydrogen, halogen, alkyl, alkoxy, acylamino, ureido or carbalkoxyamino, and R5 can also represent amino, alkylamino, hydroxyalkylamino or carbamylalkylamino. The alkyl and alkoxy groups above can contain from 1 to 6 carbon atoms and the acyl group can contain from 2 to 7 carbon atoms. The present invention also relates to a process for the preparation of the above indoanilines and to dye compositions for keratinic fibers, and in particular living human hair, containing said indoanilines.
