摘要

Reactive dyes of the formula (1) in which Qi is hydrogen, halogen or a radical of the formula (2a) or (2b),R1, R2 and R3 independently of one another are hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo, carboxyl or sulfato, and R1 in formula (1) and R1 in formula (2a) have identical or different meanings and R2 in formula (1) and R2 in formula (2a) have identical or different meanings, (R4)0-1 and (R5)0-1 independently of one another are 0 or 1 identical or different substituents from the group consisting of C1-C4alkyl, C1-C4alkoxy, halogen and sulfo, A is hydrogen or C1-C4alkyl which is unsubstituted or substituted by hydroxyl, sulfo, carboxyl or sulfato, phenyl which is unsubstituted or substituted by C1-C4alkyl, C1-C4alkoxy, C2-C4alkanoylamino, hydroxyl, carboxyl, carbamoyl, sulfo or halogen, phenyl-C1-C2alkylene which is unsubstituted or substituted in the phenyl ring by C1-C4alkyl, C1-C4alkoxy, C2-C4alkanoylamino, hydroxyl, carboxyl, sulfo, carbamoyl or halogen, or C5-C7cycloalkyl which is unsubstituted or substituted by C1-C4alkyl, B is a C2-C12alkylene radical which can be interrupted by 1, 2 or 3 members from the group consisting of -NH-, -N(CH3)- or -O- and is unsubstituted or substituted by hydroxyl, sulfo, sulfato, cyano or carboxyl, a C5-C7cycloalkylene radical or C1-C2alkylene-C5-C7cycloalkylene radical which are unsubstituted or substituted in the cycloalkylring by C1C4alkyl,C1C2alkylenephenylene radical or phenylene radical which are unsubstituted or substituted in the phenyl ring by C1C4alkyl, C1C4alkoxy, C2-C4alkanoylamino, sulfo, halogen or carboxyl, V1 and V2 independently of one another are halogen, T is a radical of the formula -CO-(CH2)m-SO2-Y (3a), -CO-CH(HaI)-CH2-HaI (3b) or -CO-C(HaI)=CH2 (3c), Hal is halogen, X is hydroxyl or Y, Y is vinyl or a radical -CH2-CH2-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.
