Mixtures of fiber-reactive dyes and use thereof for dyeing fiber materials

A dye mixture consisting essentially of three to seven fiber-reactive dyes selected from dyes of the below-indicated and -defined formulae (1) to (7) with the proviso that the dye mixture contain at least one representative of the formulae (1) or (2) or a combination thereof, at least one representative of the formulae (3) or (4) or a combination thereof, and at least one representative of the formulae (5), (6) or (7) or a combination thereof:

• ##STR11## where M is hydrogen or an alkali metal;
• m is 1, 2 or 3;
• X is cyanoamino, alkoxy of 1 to 4 carbon atoms or alkoxy of 2 to 4 carbon atoms substituted by alkoxy of 1 to 4 carbon atoms;
• Y is vinyl or is ethyl which contains in the .beta.-position a substituent which is eliminable by alkali with the formation of the vinyl group;
• Z is hydrogen or SO.sub.3 M, wherein M is defined above:
