Abstract: Reactive dye mixtures comprising at least one red dyeing dye and at least one blue, yellow, orange or brown dyeing dye and their use in methods for the dichromatic or trichromatic dyeing or printing of cellulosic fiber materials are described. The reactive dye mixtures yield dyeings or prints having good reproducibility and good all-round fastness properties.

Abstract: Dye mixtures, comprising at least one red dyeing dye of the formula (1) and at least one blue, yellow, orange or brown dyeing dye from the group of the formulae (2), (3), (4), (5) and (6), wherein B is an aliphatic bridging member, R1, R3 and R8 are each independently of the others hydrogen or C1-C4alkyl, R2, R4, R5, R9, R11, R12, R13, R14, R15 and R16 are each independently of the others hydrogen, C1-C4alkyl, C1-C4alkoxy or sulfo, R6 and R10 are each independently of the other amino or C1-C4alkyl, (R7)j denotes j identical or different substituents selected from the group C2-C4alkanoylamino, ureido, C1-C4alkyl and C1-C4alkoxy, (R17)i denotes i identical or different substituents selected from the group C2-C4alkanoylamino, ureido, sulfo, C1-C4alkyl and C1-C4alkoxy, X1, X2, X3, X4, X5 and X6 are each independently of the others halogen, 3-carboxypyridin-1-yl or 3-carbamoylpyridin-1-yl, Z1, Z2 and Z3 are each independently of the others a fibre-reactive group of the formula —SO2—Y8, (7a) or —NH—CO—(CH2)2-3—SO2—
