Reactive dye mixtures, and uses thereof in dyeing or printing methods of textile fiber materials

摘要

Dyestuff mixtures comprising at least one dye of formula (1) and at least one dye from the group of formulas (2) and (3) are particularly suitable for dyeing or printing cellulosic fibrous material, , And a dye or print having excellent reproducibility and excellent overall fastness properties is obtained. In the above formulas (1), (2) and (3), (R ₁ ) _k represents k identical or different substituents from group C ₁ -C ₄ alkoxy, C ₁ -C ₄ alkyl and sulfo , R ₂ is hydrogen or C ₁ -C ₄ alkyl, R ₃ is hydrogen or C ₁ -C ₄ alkyl, (R ₄ ) _n is a group C ₁ -C ₄ alkoxy, C ₁ -C ₄ alkyl and sulfo (R ₅ ) _q represents _q identical or different substituents from the group C ₁ -C ₄ alkoxy and C ₁ -C ₄ alkyl, X ₁ , X ₂ and X ₃ represent the same or different substituents from the group are each independently halogen, 3-carboxy-pyridin-l-yl or 3-carbamoyl-pyridin-l-yl another, T ₁ is a fiber of the formula (4a), (4b), (4c) or (4d) - reactivity Radical. In the formula (4a), (4b), (4c) and _{(4d), (R 6)} 0-2 is 0 to 2 of the groups from C ₁ -C ₄ alkyl, C ₁ -C ₄ alkoxy, and sulfonic captivity Z represents Z ₁ , Z ₂ and Z ₃ are each independently of the other vinyl or radical -CH ₂ -CH ₂ -U and U represents a hydrogen atom, And m is hydrogen, an alkali metal or one equivalent of an alkaline earth metal, k, n and q are each independently 0, 1 or 2, l, m and s are each independently Is a number of 1 or 2.
