| 摘要 |
The present invention relates to novel reactive dyes of formula I, (I), in which the variable independently denote X hydrogen, NO2, or NR<3>R<4>, Y NR<5>R<6>, OR<7>, SR<8>, or SO2R<9> or a group suitable as a leaving group under the conditions of nucleophilic, aromatic substitution, R<1> to R<9> independently hydrogen, C1-C8 alkyl, C2-C8 alkyl, in which non-adjacent CH2 groups can be replaced by oxygen atoms, imino groups, or C1-C4 alkylimino groups, and/or CH2 groups may be replaced by carbonyl groups, C2-C8 alkenyl, or a group containing an active site or the precursor of an active site, with the proviso that at least one group R<1> to R<9> is present which contains an active site or the precursor of an active site. The present invention also relates to the use of the reactive dyes of Formula I for dyeing substrates containing nucleophilic groups, and to compositions containing at least one reactive dye of formula I.
