<p>Reactive dyes of the formula (1) in which Qi is hydrogen, halogen or a radical of the formula (2a) or (2b),R, Rand Rindependently of one another are hydrogen or C-Calkyl which is unsubstituted or substituted by hydroxyl, sulfo, carboxyl or sulfato, and Rin formula (1) and Rin formula (2a) have identical or different meanings and Rin formula (1) and Rin formula (2a) have identical or different meanings, (R)and (R)independently of one another are 0 or 1 identical or different substituents from the group consisting of C-Calkyl, C-Calkoxy, halogen and sulfo, A is hydrogen or C-Calkyl which is unsubstituted or substituted by hydroxyl, sulfo, carboxyl or sulfato, phenyl which is unsubstituted or substituted by C-Calkyl, C-Calkoxy, C-Calkanoylamino, hydroxyl, carboxyl, carbamoyl, sulfo or halogen, phenyl-C-Calkylene which is unsubstituted or substituted in the phenyl ring by C-Calkyl, C-Calkoxy, C-Calkanoylamino, hydroxyl, carboxyl, sulfo, carbamoyl or halogen, or C-Ccycloalkyl which is unsubstituted or substituted by C-Calkyl, B is a C-Calkylene radical which can be interrupted by 1, 2 or 3 members from the group consisting of-NH-,-N(CH)-or-O-and is unsubstituted or substituted by hydroxyl, sulfo, sulfato, cyano or carboxyl, a C-Ccycloalkylene radical or C-Calkylene-C-Ccycloalkylene radical which are unsubstituted or substituted in the cycloalkylring by CCalkyl,CCalkylenephenylene radical or phenylene radical which are unsubstituted or substituted in the phenyl ring by CCalkyl, CCalkoxy, C-Calkanoylamino, sulfo, halogen or carboxyl, Vand Vindependently of one another are halogen, T is a radical of the formula-CO-(CH)-SO-Y ,-CO-CH(HaI)-CH-HaI or-CO-C(HaI)=CH, Hal is halogen, X is hydroxyl or Y, Y is vinyl or a radical-CH-CH-U and U is a group which can be split off under alkaline conditions, and m is the number 2, 3 or 4. are suitable for dyeing widely varying fibre materials, in particular cellulosic fibre materials, and produce dyeings with good allround properties.</p> |
