摘要

Coloring of keratinous fibers comprising applying a mixture (A) of a composition (A1) comprising a coupler such as 6-chloro-2-methyl-5-aminophenol or its salts and an oxidation base such as diamino-N,N-dihydro-pyrazolone (I) or its salts and a tinctorial composition (A2) i.e. of basic, golden based or golden shades, on the keratinous fibers in the presence of an oxidizing agent. Coloring of keratinous fibers comprising applying a mixture (A) of a composition (A1) comprising a coupler such as 6-chloro-2-methyl-5-aminophenol or its salts and an oxidation base such as diamino-N,N-dihydro-pyrazolone of formula (I) or its salts and a tinctorial composition (A2) i.e. of basic, golden based or golden shades, on the keratinous fibers in the presence of an oxidizing agent. Either R 1, R 21-6C alkyl radical (optionally substituted by -OR 5, -NR 6R 7, carboxy, sulfonic acid, carboxamido (-CONR 6R 7), a sulfonamido -SO 2NR 6R 7, heteroaryl, aryl optionally substituted by groups 1-4C alkyl, hydroxy, 1-2C alcohol, amino or 1-2C (di)alkyl amino), aryl (optionally substituted by 1-4C alkyl, hydroxy, 1-2C alcohol, amino or 1-2C (di)alkyl amino) or 5-6 membered heteroaryl (optionally substituted by 1-4C alkyl or 1-2C alcohol); R 3, R 4H or R 1, preferably H, 1-6C alkyl (optionally substituted by OH, 1-2C alkoxy, amino or 1-2C (di)alkyl amino) or phenyl (optionally substituted by amino, OH or 1-2C alkoxy); or NR 1R 25-7 membered heterocyclic ring (optionally substituted by halo, amino radicals, 1-4C (di)alkyl amino, OH, carboxy, carboxamido, 1-2C alcohol or 1-4C alkyl (optionally substituted by OH, amino, 1-4C (di)alkylamino, alcohol, carboxy or sulfonyl)), preferably pyrazolidine or pyridazolidine, optionally substituted by 1-4C alkyl, OH, 1-2C alcohol, carboxy, carboxamido, amino, 1-2C (di)alkyl amino; and NR 3R 4NR 1R 2 or 5-7 membered heterocyclic ring of which C is replaced by O or N is optionally substituted; R 5, : H, 1-4C alkyl (optionally substituted by OH, 1-2C alkoxy, -CONR 8R 9, -SO 2R 8 or aryl (optionally replaced by 1-4C alkyl, OH, 1-2C alcohol, amino or 1-2C (di)alkyl amino)); R 6, R 7R 5, -CONR 8R 9 or -SO 2R 8; and R 8, R 9H, 1-4C alkyl (optionally substituted OH or 1-2C alcohol). An independent claim is included for a device with several compartments or dyeing kit comprises a first compartment comprising (A1), a second compartment comprising (A2) and a third compartment containing an oxidizing agent/composition.
