Page/Page column 25-26, (2008/12/05)
Dye mixtures, comprising at least one dye of formula (1) and at least one dye from the group of formulae (2) and (3) wherein Q1 is C1-C4alkyl, halogen or a radical -SO2-Z, Q2 and Q3 are each independently of the other C1-C4alkoxy, Q4 is C1-C4alkoxy, C1-C4alkyl, halogen or sulfo, Q5 is C1-C4alkoxy, C1-C4alkyl, C1-C4alkanoylamino, ureido, halogen or sulfo, R1, R2 and R3 are each independently of the others hydrogen or unsubstituted or substituted C1-C4alkyl, k and q are each independently of the other the number 0 or 1, n and p are each independently of the other the number 0, 1 or 2, m is the number 0, 1, 2 or 3, t is the number 1, 2 or 3, X1, X2 and X3 are each independently of the others halogen, 3-carboxypyridin-1-yl, 3- carbamoylpyridin-1-yl or a non-fibre-reactive substituent, and T1, T2 and T3 are each independently of the others a non-fibre-reactive substituent or a fibre- reactive radical of formula (4a): -NH-(CH2)2-3-SO2-Z, (4b): -NH-(CH2)2-3-O-(CH2)2-3-SO2-Z, (4c), (4d), (4e), (4f) or (4g),wherein (R4)0-2 denotes from 0 to 2 identical or different substituents from the group halogen, C1-C4alkyl, C1-C4alkoxy and sulfo, Z is vinyl or a radical -CH2-CH2-U and U is a group removable under alkaline conditions, Q is a group -CH(Hal)-CH2-Hal or -C(Hal)=CH2, and Hal is halogen, are suitable especially for the dichromatic or trichromatic dyeing or printing of cellulosic fibre materials and yield dyeings or prints having good reproducibility and good all-round fastness properties.
