Abstract:
THE PROCESS OF USING AND COMPOSITIONS CONTAINING DYES, WHICH ARE SUITABLE FOR ONE STEP DYEING OF HAIR AND KERATIN FIBERS WITHOUT REQUIRING THE USE OF SEPARATE DYE MODIFIERS WHICH ARE EXCEPTIONALLY COLOR STABLE, HAVING THE FORMULA:
2-(R-NH-),4-R,R4-PHENOL
IN WHICH R IS SELECTED FROM THE GROUP CONSISTING OF HYDRO GEN AND ALKYL, R1 IS SELECTED FROM THE GROUP CONSISTING OF HYDROXY AND ALKYL, AND R4 WHICH CAN BE IN POSITION 5 OR 6 ON THE RING IS SELECTED FROM THE GROUP CONSISTING OF HYDROGEN, HALOGEN, HYDROXY AND ALKYL.
WHEREIN R1, R3, R4, R5, R6 and R7 each represent hydrogen, a lower alkyl or lower alkoxy and R2 represents hydrogen or a lower acyl, and their acid addition salts and their double zinc salts are usefully employed for dyeing keratinous fibers and, in particular, human hair. The indamines can be in a tautomeric form of that represented above.
WHEREIN R1 and R2 are lower alkyl, R3 and R4 are lower alkyl which can be substituted with hydroxy, amino or acylamino, R5 and R6 are hydrogen, lower alkyl or lower alkoxy, R is amino, acylamino or hydroxy, n is 1-2 and Xn( ) is an anion, are useful for dyeing keratinous fibers and, in particular, human hair. These salts can be in a tautomeric form of that represented above.
Abstract:
