Claims8
A dye mixture, comprising at least one dye of formula
- and at least one dye from the group of formulae
- wherein
- R3 is hydrogen or unsubstituted or substituted C1-C4 alkyl,
- q is 0 or 1,
- t is the number 1, 2 or 3,
- X1, and X3 are each independently of the others halogen, 3-carboxypyridin-1-yl, or 3-carbamoylpyridin-1-yl, and
- T1, and T3 are each independently of the others a fibre-reactive radical of formula
- wherein
- (R4)0-2 denotes from 0 to 2 identical or different substituents from the group halogen, C1-C4 alkyl, C1-C4 alkoxy 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.
