    The invention relates to diaminopyrazole derivatives having the following structure (I), wherein R 1 represents an alkyl or alkenyl radical bearing at least one substituent selected from among OR, NRR′, SR, SOR, SO 2 R, COOR, CONRR′, PO(OH) 2 , SO 3 X, NHCONRR, a non-cationic heterocycle, an aryl, a halogen. R 2 and R 3 are different from H and represent, independently of each other, an alkyl or alkenyl group; R 2 and R 3 , 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; R 2 and R 3 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.
    该发明涉及具有以下结构(I)的二氨基吡唑衍生物,其中R1代表至少一个取代基选自OR、NRR′、SR、SOR、SO2R、COOR、CONRR′、PO(OH)2、SO3X、NHCONRR、非阳离子杂环、芳基、卤素的烷基或烯基基团。R2和R3与H不同,分别代表烷基或烯基基团;R2和R3与它们连接的氮原子一起,可以形成一个可能包含至少另一个来自N、O和S的杂原子的杂环;R2和R3或它们与连接的氮原子形成的杂环可以被上述至少一个取代基取代。相同或不同的R、R′基选自氢原子、烷基或烯基基团;R和R′与它们连接的氮原子一起,可以形成至少有4个环成员的杂环,该环成员可以包含至少一个来自O、N和S的额外杂原子。X代表氢、碱土金属或碱金属原子或铵基团。该发明还涉及使用这些染料组合物和染色方法。

    The subject matter of the present invention is directed to a process for producing 4,5-diaminopyrazole derivatives of the general formula (I) ##STR1## where R.sub.1 and R.sub.2 independently designate hydrogen, a C.sub.1 - to C.sub.6 -alkyl radical or a C.sub.2 - to C.sub.4 -hydroxyalkyl radical, which can be used as dye precursors, for example for hair dyes, and to new pyrazole derivatives. When using the process according to the invention good yields of isomer-pure 4,5-diaminopyrazole derivatives of general formula (I) can be obtained.
