Mixtures of dyes containing fibre-reactive groups and their use of dyeing fibre materials.

摘要

A dye mixture which contains from three to seven fibre-reactive dyes selected from dyes of the general formulae (1) to (7) indicated and defined below, with the proviso that the mixture includes at least one representative from formulae (1) and/or (2), at least one representative from formulae (3) and/or (4) and at least one representative from formulae (5) and/or (6) and/or (7): in which formulae: M is hydrogen or an alkali metal; m is the number 1, 2 or 3; X is cyanoamino, alkoxy with 1 to 4 carbon atoms or alkoxy with 2 to 4 carbon atoms which is substituted by alkoxy with 1 to 4 carbon atoms; Y is vinyl or is ethyl which in the ss-position contains a substituent which can be eliminated by alkali to form the vinyl group; R, R1 to R9 are hydrogen or substituents; A is alkylene of 2 to 6 carbon atoms which may be substituted; V is a carbonyl group of the formula -CO-O- or an oxy group of the formula -O-; one group -SO3-M in formula (4) and in formula (7) is bonded in the meta- or para-position with respect to the amino group on the naphthalene ring system of the aminonaphthol residue.
