| 摘要 |
A subject-matter of the present invention is a composition for dyeing keratinous fibers, in particular human keratinous fibers, such as the hair, comprising: —at least 25% by weight of at least one fatty substance not comprising a carboxylic acid functional group; —at least one aminopyrazolopyridine oxidation base chosen from the bases of formula (I), the bases of formula (II) and their addition salts, their solvates and the solvates of their salts: —at least one coupler; and —at least one oxidizing agent. The composition of the invention is suitable for use in oxidation dyeing and results in a coloration with shades which are varied, intense or chromatic, powerful, attractive, not very selective and highly resistant to the various assaults which the hair may be subjected to, such as shampooing operations, sweat, permanent reshapings and light. In particular, it makes it possible to obtain an optimized color result with a good power, a good dyeing capacity and a good equal depth.; |

1. A composition for dyeing keratinous fibers comprising:
a) at least about 25% by weight of at least one fatty substance, wherein said at least one fatty substance does not comprise a carboxylic acid functional group; b) at least one aminopyrazolopyridine oxidation base chosen from bases of formula (I), bases of formula (II), and the addition salts, solvates and solvates of the salts thereof: wherein: R1, R2, R3, R4 and R5, which are identical or different, are chosen from hydrogen atoms; halogen atoms; —NHSO3H radicals; hydroxyl radicals; (C1-C4)alkyl radicals; (C1-C4)alkoxy radicals; (C1-C4)alkylthio radicals; mono(C1-C4)alkylamino radicals; di(C1-C4)alkylamino radicals wherein the two alkyl groups can, in conjunction with the nitrogen atom to which they are bonded, form a ring which is optionally interrupted by at least one atom chosen from nitrogen, oxygen and sulphur atoms; heterocycles; nitro radicals; phenyl radicals; carbonyl radicals; alkoxy(C1-C4)carbonyl radicals; carboxamido radicals; cyano radicals; amino radicals; sulphonyl radicals; —CO2H radicals; —SO3H radicals; —PO3H2 radicals; —PO4H2 radical; and groups wherein R′″ is chosen from oxygen and nitrogen atoms, Q is chosen from oxygen atoms, NH groups, and NH(C1-C4)alkyl groups, and Y is chosen from hydroxyl, amino, (C1-C4)alkyl, (C1-C4)alkoxy, (C1-C4)alkylamino and di(C1-C4)alkylamino radicals; wherein: Z1 and Z2, which may be identical or different, are chosen from single covalent bonds and divalent radicals chosen from: —O(CH2)p— radicals, wherein p is an integer ranging from 0 to 6; and —NR′6(CH2)q(C6H4)t— radicals, wherein q is an integer ranging from 0 to 6, t is chosen from 0 and 1, and R′6 is chosen from hydrogen atoms and C1-C6 alkyl radicals optionally substituted by at least one hydroxyl group; Z1 may also be chosen from divalent radicals —S—, —SO— and —SO2— when R′1 is a methyl radical; R′1 and R′2, which may be identical or different, are chosen from hydrogen atoms; C1-C10 alkyl radicals, optionally substituted and optionally interrupted by a group chosen from heteroatoms, O, N, Si, S, SO and SO2; halogen atoms; SO3H radicals; substituted and unsubstituted and saturated, unsaturated and aromatic 5- to 8-membered rings optionally including at least one group chosen from heteroatoms, N, O, S, SO2 and —CO—, wherein the ring may be at least one of cationic and substituted by a cationic radical; —N+R17R18R19 groups, wherein R17, R18 and R19 are chosen from linear and branched C1-C5 alkyls optionally substituted by at least one hydroxyl group; when Z1 or Z2 respectively represents a covalent bond, then R′1 or R′2 can respectively be chosen from optionally substituted C1-C6 alkylcarbonyl radicals; —O—CO—R, —CO—O—R, NR—CO—R′ and —CO—NRR′ radicals wherein R and R′, which may be identical or different, are chosen from hydrogen atoms and optionally substituted C1-C6 alkyl radicals; R′3, R′4 and R′5, which may be identical or different, are chosen from hydrogen atoms; hydroxyl radicals; C1-C6 alkoxy radicals; C1-C6 alkylthio radicals; amino radicals; monoalkylamino radicals; di(C1-C6) alkylamino radicals wherein the alkyl radicals can form, with the nitrogen atom to which they are attached, an optionally saturated and optionally aromatic 5- to 8-membered heterocycle which can include at least one group chosen from heteroatoms, N, O, S, SO2 and CO, it being possible for the heterocycle to be at least one of cationic and substituted by a cationic radical; optionally substituted C1-C6 alkylcarbonyl radicals; —O—CO-R, —OO—O—R, NR—CO—R′ and —CO—NRR′ radicals wherein R and R′, which may be identical or different, are chosen from hydrogen atoms and optionally substituted C1-C6 alkyl radicals; halogen atoms; —NHSO3H radicals; optionally substituted C1-C4 alkyl radicals; saturated, unsaturated and aromatic carbon rings which are optionally substituted; R′3, R′4 and R′5 can form, in pairs, a ring which is optionally partially saturated; X is chosen from ions and groups of ions which makes it possible to provide the electrical neutrality of the derivative of formula (II); wherein at least one of the groups R′1 and R′2 is a cationic radical; c) at least one coupler; and d) at least one oxidizing agent. |
