titleOfInvention | Isatin derivatives for dyeing keratin-containing fibres |
abstract | PCT No. PCT/EP95/00848 Sec. 371 Date Sep. 17, 1996 Sec. 102(e) Date Sep. 17, 1996 PCT Filed Mar. 8, 1995 PCT Pub. No. WO95/24886 PCT Pub. Date Sep. 21, 1995The process of coloring keratin-containing fibers by contacting the fibers with an isatin derivative corresponding to formula (I): <IMAGE> (I) in which R1 is a hydroxy group, an optionally C1-4-alkyl- or phenyl-substituted amino group, a C3-8 alkenyl, dihydroxy-(C3-6)-alkyl, trihydroxy-(C4-6)-alkyl, tetrahydroxy-(C5-6)-alkyl, pentahydroxy-C6-alkyl, C2-4-aminoalkyl, C1-4-sulfoalkyl group, an optionally C1-4-alkyl-substituted 2-furylmethyl, 2-thienylmethyl, 2-pyridylmethyl, 3-pyridylmethyl, 4-pyridylmethyl group or an aralkyl group corresponding to formula (II): <IMAGE> (II) in which R6 and R7 independently of one another represent hydrogen, halogen atoms, hydroxy groups, amino groups optionally substituted by C1-4 alkyl or phenyl, C1-4 alkyl groups, C1-4 alkoxy groups, carboxy groups or sulfo groups and R8 is hydrogen, a C1-4 alkyl group or a C2-4 hydroxyalkyl group and x=0, 1 or 2, and R2, R3, R4 and R5 independently of one another represent hydrogen, hydroxy groups, halogen atoms, nitro groups, sulfo groups, carboxyl groups, C1-4 alkyl groups, C1-4 alkoxy groups or NR9R10 groups, wherein R9 and R10 independently of one another represent hydrogen, C1-4 alkyl groups or C2-4 hydroxyalkyl groups, and two adjacent groups R3, R4 and R5 may represent an alkylenedioxy group containing 1 to 4 carbon atoms, and water-soluble salts thereof. |
