Patent ID: 7211117

Claim:
A composition for dyeing keratin fibers comprising: a cosmetic medium suitable for dyeing human keratin fibers, wherein said medium is water or a mixture of water and at least one organic solvent suitable for dyeing human keratin fibers, and at least one dye, comprised in said medium and chosen from formulae (I), (Ibis), (II) and (IIbis) and the tautomeric forms thereof and the addition salts thereof: wherein: Ar 1 , which may be identical or different, is chosen from aryl optionally substituted with at least one Z group; HET, which may be identical or different, is chosen from heterocycles optionally substituted with at least one Z′ group; A, which may be identical or different, is chosen from O; NH; N-alkyl; N-hydroxyalkyl; ammonium, N-alkylammonium, N-(hydroxyalkyl)ammonium, N,N-dialkylammonium, N,N-di(hydroxyalkyl)ammonium, and N-(hydroxyalkyl) N-(alkyl)ammonium wherein the two alkyl groups may form, together with the nitrogen atom to which they are bonded, at least one cyclic group optionally interrupted by at least one atom chosen from nitrogen, oxygen and sulphur; R 1 to R 6 , Z, and Z′, which may be identical or different, are each chosen from hydrogen, halogen, —NHSO 3 H; hydroxyl; alkyl; alkoxy; alkylthio; monoalkylamino, and dialkylamino, wherein the two alkyl groups of the dialkylamino may form together with the nitrogen atom to which they are bonded, at least one cyclic group optionally interrupted by at least one atom chosen from nitrogen, oxygen and sulphur; heterocycles and nitro; aryl; acyl; alkoxycarbonyl; carboxamido; cyano; —CO 2 H; —SO 3 H; —PO 3 H 2 ; and —PO 4 H 2 ; A′, which may be identical or different, is chosen from hydrogen; hydroxyl; amino; (hydroxyalkyl)amino; monoalkylamino; (dihydroxyalkyl)amino, (hydroxyalkyl)(alkyl)amino, (dialkyl)amino, wherein the two alkyl groups of the (dialkyl)amino may form, together with the nitrogen atom to which they are bonded, at least one cyclic group optionally interrupted by at least one atom chosen from nitrogen, oxygen and sulphur; and R is chosen from hydrogen, halogens, hydroxyl, alkoxy, and alkylthio.
