Abstract (en)
[origin: WO0246165A1] The invention concerns novel diaminopyrazole derivatives of formula (I), wherein: R1 represents C1-C6 alkyl or C2-C6, preferably up to C4, alkenyl, linear or branched, bearing at least a substituent selected among OR, NHR, NRR', SR, SO2R, COOH, CONH2, CONRR', PO(OH)2, SH, SO3X, a non-cationic heterocycle, Cl, Br or I; X represents H, Na, K or NH4; R and R', identical or different, represent C1-C6 alkyl or C2-C6, preferably up to C4, alkenyl, linear or branched, unsubstituted or substituted by one or several functional groups selected among OH, NH2, OR, NHR, NRR', SR, SOR, SO2R, COOH, CONH2, CONRR', PO(OH)2, SH, SO3X, a non-cationic heterocycle, Cl, Br or I, X, R and R' having the definitions mentioned above; R2 represents H, or C1-C6 alkyl or C2-C6, preferably up to C4, alkenyl, linear or branched, unsubstituted or substituted by one or several functional groups selected among OH, NH2, OR, NHR, NRR', SR, SOR, SO2R, COOH, CONH2, CONRR', PO(OH)2, SH, SO3X, a non-cationic heterocycle, Cl, Br or I, X, R and R' having the definitions mentioned above; and their physiologically acceptable salts, and their use for oxidation dyeing of keratinous fibres, in particular human hair.
