Abstract: A dye mixture comprising at least one dye of formula (1) and at least one dye from the group of formulae (2) and (3), wherein (R1)k denotes k identical or different substituents from the group C1-C4alkoxy, C1-C4alkyl and sulfo, R2 is hydrogen or C1-C4alkyl, R3 is hydrogen or C1-C4alkyl, (R4)n denotes n identical or different substituents from the group C1-C4alkoxy, C1-C4alkyl and sulfo, (R5)q denotes q identical or different substituents from the group C1-C4alkoxy and C1-C4alkyl, X1, X2 and X3 are each independently of the others halogen, 3-carboxypyridin-1 -yl or 3-carbamoylpyridin-1 -yl, Τ1 is a fibre-reactive radical of formula (4a), (4b), (4c) or (4d), wherein (R6)0-2 denotes from 0 to 2 identical or different substituents from the group C1-C4alkyl, C1- C4alkoxy and sulfo, Me means methyl, and Et means ethyl, Z, Z1, Z2 and Z3 are each independently of the others vinyl or a radical -CH2-CH2-U and U is a group removable under alkaline conditions, M is hydrogen, an alkali metal or one equivalent of an alkaline earth metal, k, n and q are each independently of the others the number 0, 1 or 2, and I, m and s are each independently of the others the number 1 or 2, are suitable especially for the dyeing or printing of cellulosic fibre materials, exhibit good build-up, and yield dyeings and prints having good reproducibility and good all-round fastness properties.
