Fibre-reactive anthraquinone dyes, process for their preparation, and their use

摘要

Anthraquinone dyes of the formula (1) in which R1, R2, R3, R4 and R5 independently of one another are hydrogen or are substituted or unsubstituted C1-C12alkyl, X1 and X2 independently of one another are chlorine or fluorine, B1 is a C2-C12alkylene radical which is unsubstituted or substituted by hydroxyl, sulfo or sulfato and is uninterrupted or is interrupted by oxygen; or is a cyclohexylene radical, C1-C4alkylene-cyclohexylene radical, cyclohexylene-C1-C4alkylene radical, C1-C4alkylene-cyclohexylene-C1-C4alkylene radical or cyclohexylene-methylene-cyclohexylene radical which is unsubstituted or is substituted in the cyclohexylene ring by C1-C4alkyl; or is a C1-C4alkylene-phenylene radical, phenylene-C1-C4alkylene radical or C1-C4alkylene-phenylene-C1-C4alkylene radical which is unsubstituted or is substituted in the phenylene ring by C1-C4alkyl, C1-C4alkoxy, C2-C4alkanoylamino, sulfo, halogen or carboxyl, B2 is an aromatic bridge member, Y is hydrogen, substituted or unsubstituted C1-C12alkyl, or a radical of the benzene or naphthalene series, and m is the number 0 or 1, with the proviso that, if m is the number 0, the radical Y contains a fibre-reactive group with the formula (2a) or (2b) where Hal is halogen.
