The present invention relates to azo dyes of formula wherein

Disperse azo dyes, a process for the preparation thereof and the use thereof

A dye mixture, comprising at least one blue dyeing dye of the formula (1), wherein Qrepresents a bivalent radical of formula (4), (4) or (4), wherein Xdenotes chlorine or fluorine, Ris hydrogen or C-Calkyl, Ris hydrogen, C-Calkyl, C-Calkoxy or sulfo, Yis vinyl or a radical &#x2014;CH&#x2014;CH&#x2014;U and U is a leaving group removable under alkaline conditions, Ris hydrogen or C-Calkyl that is unsubstituted or substituted by hydroxy, sulfo, sulfato, cyano, carboxy, C-Calkoxy or phenyl, r and s are each independently of the other the number 0 or 1, and t is the number 0, 1 or 2, and the sum of r, s and t is 2 or 3 and at least one yellow or red dyeing reactive dye is suitable especially for the dichromatic or trichromatic dyeing or printing of natural or synthetic polyamide fibre materials and yield dyeings or prints having good reproducibility and good all-round fastness properties. 

Mixtures of reactive dyes and their use in a method of di- or trichromatic dyeing or printing

Reactive dyes of formula wherein Ris hydrogen or unsubstituted or substituted C-Calkyl, (R)denotes s identical or different substituents from the group halogen, nitro, unsubstituted or halo-substituted C-Calkyl, C-Calkanoylamino, C-Calkylsulfonyl, carbamoyl, sulfamoyl and sulfo,Me is chromium, cobalt or iron,E is a bivalent radical of formula wherein X denotes chlorine or fluorine, T is a fiber-reactive radical of formula&#x2014;NH&#x2014;(CH)&#x2014;SO&#x2014;Z&#x2003;&#x2003;(2a),&#x2014;NH&#x2014;(CH)&#x2014;O&#x2014;(CH)&#x2014;SO&#x2014;Z&#x2003;&#x2003;(2b), (R)denotes from 0 to 2 identical or different substituents from the group halogen, C-Calkyl, C-Calkoxy and sulfo, Z is vinyl or a &#x2014;CH&#x2014;CH&#x2014;U radical and U is a group that is removable under alkaline conditions, Q is a &#x2014;CH(Hal)-CH-Hal or &#x2014;C(Hal)=CHgroup,s is the number 0, 1, 2 or 3, q is the number 0 or 1, A denotes a bivalent radical of formula wherein R, R, X, T, m, n, q and s are as defined above, Rand Rdenote hydrogen or C-Calkyl, Rand Rrepresent, each independently of the other, identical or different substituents from the group hydroxyl, halogen, nitro, unsubstituted or halo-substituted C-Calkyl, C-Calkoxy, C-Calkanoylamino, C-Calkylsulfonyl, carbamoyl, sulfamoyl and sulfo, and t and u are each independently of the other the number 0, 1, 2 or 3,are especially suitable for dyeing synthetic polyamide fiber materials and yield dyeings or prints having good wet-fastness properties.
