    • The invention relates to diaminopyrazole derivatives having the following structure (I), wherein R1 represents an alkyl or alkenyl radical bearing at least one substituent selected from among OR, NRR', SR, SOR, SO2R, COOR, CONRR', PO(OH)2, SO3X, NHCONRR, a non-cationic heterocycle, an aryl, a halogen. R2 and R3 are different from H and represent, independently of each other, an alkyl or alkenyl group; R2 and R3, together with the nitrogen atom to which they are attached, can form a heterocycle possibly comprising at least one other heteroatom selected from among N, O and S; R2 and R3 or the heterocycle that they form with the nitrogen to which they are attached can be substituted by at least one substituent defined above. The identical or different R, R' groups are selected from a hydrogen atom, an alkyl or alkenyl group; R and R', together with the nitrogen atom to which they are attached, can form a heterocycle having at least 4 ring members that can contain at least one additional heteroatom selected from among O, N and S. X represents a hydrogen, an alkaline-earth or alkali metal atom or an ammonium group. The invention also relates to the dyeing compositions and the dyeing methods using same.
    • 本发明涉及具有以下结构(I)的二氨基吡唑衍生物,其中R 1表示具有至少一个选自OR,NRR',SR,SOR,SO 2 R,COOR,CONRR',PO(OH) 2,SO 3 X,NHCONRR,非阳离子杂环,芳基,卤素。 R2和R3不同于H并且彼此独立地表示烷基或烯基; R2和R3与它们所连接的氮原子一起可以形成可能包含至少一个选自N,O和S的其它杂原子的杂环; R2和R3或它们与它们连接的氮形成的杂环可以被至少一个上述定义的取代基取代。 相同或不同的R,R'基团选自氢原子,烷基或烯基; R和R'与它们所连接的氮原子一起可以形成具有至少4个可以含有至少一个选自O,N和S的杂原子的环成员的杂环.X代表氢,碱 - 碱或碱金属原子或铵基。 本发明还涉及染色组合物和使用其的染色方法。
