Abstract:
The present invention relates to novel reactive dyes of formula I, (I), in which the variable independently denote X hydrogen, NO2, or NR R , Y NR R , OR , SR , or SO2R or a group suitable as a leaving group under the conditions of nucleophilic, aromatic substitution, R to R 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 to R 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.

Abstract:
The present invention relates to novel reactive dyes of the formula (I) where R to R are independently hydrogen, C1-C8-alkyl, C2-C8-alkyl, wherein nonadjacent CH2 groups may be replaced by oxygen atoms or imino or C1-C4-alkylimino groups and/or CH2 groups by carbonyl groups, C2-C8-alkenyl, aryl, arylalkylene or a moiety containing a reactive group or the precursor of a reactive group, with the proviso that at least one of R to R is a moiety which contains a reactive group or the precursor of a reactive group. The present invention further relates to the use of the reactive dyes of the formula (I) for dyeing substrates containing nucleophilic groups and to preparations containing at least one reactive dye of the formula (I).
