摘要

Composition comprises: one or more oxidation bases comprising 2-[[2-(4-amino-phenylamino)-ethyl]-(2-hydroxy-ethyl)-amino]-ethanol (I) or its addition salts with an acid; and one or more oxidation bases having diamino-N,N-dihydro-pyrazolone structure (II) in a medium. Composition comprises: one or more oxidation bases comprising 2-[[2-(4-amino-phenylamino)-ethyl]-(2-hydroxy-ethyl)-amino]-ethanol (I) or its addition salts with an acid; and one or more oxidation bases having diamino-N,N-dihydro-pyrazolone structure of formula (II) in a medium. Either R 1>-R 4>1-10C, preferably 1-6C alkyl (optionally substituted by one or more OR 5>, NR 6>R 7>, carboxy, sulfonic group, carboxamido group of formula (CONR 6>R 7>), sulfonamido group of formula (SO 2NR 6>R 7>), heteroaryl, aryl optionally substituted by one or more 1-4C alkyl, hydroxy, 1-2C alkoxy, amino, or 1-2C(di)alkylamino), aryl (optionally substituted by one or more 1-4C alkyl, hydroxy, 1-2C alkoxy, amino, or 1-2C(di) alkylamino), 5 or 6-membered heteroaryl ring (optionally substituted by one or more 1-4C alkyl or 1-2C alkoxy) or H; or NR 1>R 2>, NR 3>R 4>5 or 7 membered heterocycle optionally saturated and comprising halo, amino, 1-4C(di)alkylamino, hydroxy, carboxy, carboxamido, (1-2C)alkoxy, or 1-4C alkyl (optionally substituted by one or more OH, amino, (di)-alkylamino, alkoxy, carboxy or sulfonyl); or NR 3>R 4>optionally substituted 5 or 7-membered heterocyclic ring whose carbon atoms may be replaced by O or N; R 5>-R 7>H, 1-4C alkyl (optionally substituted by OH, 1-2C alkoxy, carboxamido group of formula (CONR 8>R 9>) (a), sulfonyl group of formula (SO 2NR 8>) (b), or aryl optionally substituted by 1-4C alkyl, hydroxy, 1-2C alkoxy, amino, or 1-2C(di)alkylamino) or aryl (optionally substituted by 1-4C alkyl, hydroxy, 1-2C alkoxy, amino, or 1-2C(di)alkylamino), where R 6>and R 7>is preferably (a) or (b); and R 8>, R 9>H or 1-4C alkyl (optionally substituted by hydroxy or 1-2C alkoxy). Independent claims are included for: (1) dyeing keratin fibers, comprising applying the composition on the keratin fibers in the presence of one or more oxidizing agents during a sufficient time to develop the desired color; and (2) multi-compartment device comprising first compartment containing (I) and a second compartment containing one or more oxidizing agents.
