Abstract: Composition (A) comprises, in a medium, at least one oxidation base comprising diamino-N,N-dihydro-pyrazolone derivatives of formula (I), and their addition salts, solvates and solvates of their salts; and at least one coupler comprising 4-aminoindole derivatives of formula (II), and their addition salts, solvates and solvates of their salts. Composition (A) comprises, in a medium, at least one oxidation base comprising diamino-N,N-dihydro-pyrazolone derivatives of formula (I), and their addition salts, solvates and solvates of their salts; and at least one coupler comprising 4-aminoindole derivatives of formula (II), and their addition salts, solvates and solvates of their salts. Either R1, R2 : 1-6C alkyl (optionally substituted by OR5, NR6R7, carboxyl, sulfonic group, carboxamido group, CONR6R7, SO 2NR6R7, heteroaryl, aryl (optionally substituted by 1-4C alkyl), hydroxy, 1-2C alkoxy, amino, or (di)alkyl(1-2C)amino)), aryl (optionally substituted by 1-4C alkyl, hydroxyl, 1-2C alkoxy, amino, (di)alkyl(1-2C)amino), or 5-6 membered heteroaryl ring (optionally substituted by (1-4C)alkyl, or (1-2C)alkoxy); and R3, R4 : H or R1; or NR1R2 : optionally saturated 5-7 membered heterocycle (optionally substituted by halo, amino, (di) alkyl(1-4C)amino, hydroxy, carboxy, carboxamido, (1-2C) alkoxy), where the 1-4C alkyl is optionally substituted by hydroxy, amino, (di)-alkylamino, alkoxy, carboxy or sulfonyl; or NR3R4 : optionally saturated 5-7 membered heterocycle ((optionally substituted by halo, amino, (di) alkyl(1-4C)amino, hydroxy, carboxy, carboxamido, (1-2C) alkoxy), where the 1-4C alkyl is optionally substituted by hydroxy, amino, (di)-alkylamino, alkoxy, carboxy or sulfonyl) or 5-7 membered heterocycle ring whose carbon atoms may be optionally substituted by O or N; R5, R6, R7 : H or 1-4C alkyl group (optionally substituted with OH, 1-2C alkoxy, carboxamido, CONR8R9, SO 2R8, or aryl (optionally substituted by 1-4C alkyl, hydroxy, 1-2C alkoxy, amino, (di)alkyl (1-2C) amino); R6, R7 : CONR8R9 or SO 2R8; R8, R9 : H or 1-4C alkyl (optionally substituted by hydroxyl or 1-2C alkoxy); R1a : H, saturated 1-6C alkyl, optionally interrupted by an oxygen atom or NR7a, optionally substituted with OH, or NR7aR8a; R2a, R3a : H, saturated 1-6C, preferably 1-4C alkyl (optionally substituted by one or more OH), 1-6C alkyl carboxylate, carboxyl group or CONR7aR8a; R4a, R5a : H or 1-6C alkyl; R6a : halo, 1-10C alkyl (optionally interrupted by heteroatoms of O or NR9a and/or optionally substituted by one or more OH or NR7aR8a), carboxyl group, 1-10C alkyl carboxylate, CONR7aR8a, 1-10C-alkoxy- or (poly)hydroxy-1-10C alkoxy, (poly)(1-10C)alkoxy(1-10C)alkyloxy, or -O-Ak1-NR9aR10a; Ak1 : linear 1-8C or branched 3-8C divalent alkylene radical, optionally interrupted by one or more O and/or NR7a; R7a, R8a : H or 1-8C alkyl optionally substituted by one or more OH; either R9a, R10a : optionally saturated 1-4C alkyl group; or NR9aR10a : optionally saturated 5-8 membered ring, one of the links can be an oxygen atom or a NR11a; and R11a : 1-4C alkyl, optionally substituted by one or more OH, NR7aR8a or H. Independent claims are included for: (1) process for dyeing keratin fibers comprising applying the composition on the keratin fibers in the presence of at least one oxidizing agent for a time sufficient to develop the desired coloration; and (2) multi-compartment device in which a first compartment contains a dye composition (A) and a second compartment contains at least one oxidizing agent.
