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, for example, formula (101) especially suitable for dyeing synthetic polyamide fibre materials and which yield dyeings or prints having good wet-fastness properties, and a process for their preparation. 

Reactive dyes, their preparation and their use

The present invention relates to dyes of formula (1), wherein each of the residues Dand Drepresents a radical of formula (2), wherein Arrepresents the tetravalent radical of a carbocylic or heterocyclic aromatic compound, R, Rand Rare each independently of the other hydrogen, C-Calkyl, C-Calkoxy, halogen, &#x2014;OH, &#x2014;CN, &#x2014;NO, &#x2014;CF, &#x2014;SOH, &#x2014;NHCOR, &#x2014;COOR, &#x2014;CONRR, &#x2014;SONRR, &#x2014;NRSOR, &#x2014;SOR&#x2014; or &#x2014;ZCHCHQ, wherein Z is &#x2014;O&#x2014;, &#x2014;SO&#x2014;, &#x2014;NR&#x2014;, &#x2014;CONH&#x2014; or &#x2014;NHCO&#x2014;, Q represents &#x2014;OH, C-Calkyl, &#x2014;SOR&#x2014;, &#x2014;NHR&#x2014;, &#x2014;OCHCHOH, &#x2014;SOCHCHOH or &#x2014;NHCHCHOH, Ris C-Calkyl, R, R, R, R, R, R, R, Rand Rare each independently of the others hydrogen or C-Calkyl, and Ris C-C2alkyl, with the proviso that at least one of the residues Dand Dis a radical of formula (2) wherein Ris &#x2014;COOR, &#x2014;SONRR, &#x2014;SOR&#x2014; or &#x2014;ZCHCHQ, dichromatic and trichromatic mixtures containing these dyes and the use of these dyes for dyeing or printing hydroxyl group-containing or nitrogen-containing fibre materials.
