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, piperidonoalkyl, 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.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 142 words
An indoaniline having the formula ##STR65## wherein: R 1 represents hydrogen, halogen, alkyl or alkoxy; R 2 represents alkyl and hydroxyalkyl, R 3 represents piperidinoalkyl, morpholinoalkyl or R 2 and R 3 together with the nitrogen atom to which they are attached form a heterocycle selected from piperidino and morpholino; R 4 , r 5 and R 6 each independently represent hydrogen, halogen, alkyl, alkoxy, acetylamino, ureido or carbalkoxyamino, with the proviso that at least one of R 4 , R 5 and R 6 is other than hydrogen or halogen and that at least two of said R 4 , R 5 and R 6 are other than hydrogen when R 4 or R 6 is methyl and R 5 can further represent amino, alkylamino, hydroxyalkylamino and carbamylalkylamino, wherein the alkyl and alkoxy groups contain from 1 to 6 carbon atoms.
