Summary:Mixtures comprising a compound of the formula (16a) and a compound of the formula (16b) in which K is the radical of a coupling component, s is the same in the compounds of formulae (16a) and (16b) and is the number 1 or 2, R and R' are each hydrogen, sulfo, hydroxyl, C1-C4alkoxy, halogen or cyano, A is C1-C6alkylene which is optionally substituted by halogen, hydroxyl, sulfato, carboxyl, cyano, C2-C4alkanoyloxy, C1-C4alkoxycarbonyl or carbamoyl or interrupted by a group -O- or -NR''-, or is C1-C6alkylenephenylene which is unsubstituted or substituted in the phenyl part by C1-C4alkyl, C1-C4alkoxy, halogen or sulfo, and R'' is hydrogen or C1-C4alkyl, and the ratio of the compounds of formulae (16a) and (16b) is about 1:1, are suitable as fibre-reactive dyes for dyeing or printing widely varying fibre materials.
