The present invention relates to a colorant mixture comprising 

Colorant mixtures

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

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.
