Abstract
Reactive dyes of formula 1 wherein A is the radical of a monoazo, polyazo, metal complex azo, anthraquinone, phthalocyanine, formazan or dioxazine chromophore, R1, R2 and R3 are each hydrogen or unsubstituted or substituted C1-C4alkyl, X1 and X2 are halogen, B is an organic bridging member, T is a reactive radical as defined herein and V1 and V2 are each independently of the other N, C—H, C—Cl or C—F, give prints that are distinguished by brilliant color shades and good all-round properties.
