ABSTRACT:
Dye mixtures, comprising at least one dye of formulaand at least one dye from the group of formulaewhereinB1, B2and B3are each independently of the others an organic bridging member,Q1is C1-C4alkyl, halogen or a radical —SO2-Z,Q2and Q3are each independently of the other C1-C4alkoxy,Q4is C1-C4alkoxy, C1-C4alkyl, halogen or sulfoQ5is C1-C4alkoxy, C1-C4alkyl, C1-C4alkanoylamino, ureido, halogen or sulfo,R1, R2, R3, R4, R5, R6, R7, R8and R9are 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, X3, X4, X5and X6are each independently of the others halogen, andT1, T2and T3are each independently of the others a non-fiber-reactive substituent or a fiber-reactive radical of formulawherein(R10)0-2denotes 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, andHal is halogen, are suitable especially for the dichromatic or trichromatic dyeing or printing of cellulosic fiber materials and yield dyeings or prints having good reproducibility and good all-round fastness properties.
