<p>Dye mixtures comprising at least one dye of formula (1), at least one dye of formula (2), and at least one dye from the group of formulae (3), (4), (5), (6), (7), (8) and (9), wherein R1 is C1-C4alkoxy, R2 is hydrogen, C1-C4alkyl or C1-C4alkoxy, R3, R5 and R6 are each independently of the others hydrogen or unsubstituted or substituted C1-C4alkyl, (R4)0-2 denotes from 0 to 2 identical or different substituents from the group halogen, C1-C4alkyl, C1-C4alkoxy and C2-C4alkanoylamino, R7, R8, R9, R10, R11, R12, R13, R14, R15, R16, R17, R18, R19 and R20 are each independently of the others hydrogen, C1-C4alkyl, C1-C4alkoxy, sulfo or halogen, X1 and X2 are halogen, each Y, independently of any other(s), is a -CH(Hal)-CH2-Hal or -C(Hal)=CH2 group and Hal is halogen, and each Z, independently of any other(s), is vinyl or a -CH2-CH2-U radical and U is a group that can be removed under alkaline conditions, are suitable for dyeing or printing cellulose-containing and polyamide-containing fibre materials and yield dyeings having a high degree of constancy of shade and good fastness properties, while at the same time exhibiting good build-up behaviour.</p> |
