Reactive dyes of formula (1), 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, X is chlorine, T is a fiber-reactive radical of formula &#x2014;NH&#x2014;(CH)&#x2014;SO&#x2014;Z (2), &#x2014;NH&#x2014;(CH)&#x2014;O&#x2014;(CH)&#x2014;SO&#x2014;Z (2), formula (2), formula (2), formula (2), formula (2), (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(HaI)&#x2014;CH&#x2014;HaI or &#x2014;C(HaI)&#x2550;CHgroup, Hal is halogen, s is the number 0, 1, 2 or 3 and m, n, r and q are each independently of the others the number 0 or 1, are especially suitable for dyeing synthetic polyamide fiber materials and yield dyeings or prints having good wet-fastness properties. 

Reactive dyes, their preparation and their use

A method of dyeing or printing textile fiber materials, which comprises bringing the fiber material into contact with (a) at least one reactive dye containing at least one anionic group, (b) at least one compound which reduces the ionic character of the anionic group, and (c) at least one nucleophilic compound, yields dyeings or prints having deep hues and very good fastness properties.

Method of dyeing or printing textile fibre materials using reactive dyes

A method of dyeing or printing synthetic polyamide fiber materials, wherein (a) the fiber material is dyed or printed with at least one reactive dye, and (b) the dyed or printed fiber material is subjected to after-treatment with a reducing agent, the fiber material not being treated with polycondensable or polymerizable compounds for fixing the dye on the fiber, results in dyeings and printings that are distinguished by good fastness properties.

Method of dyeing or printing synthetic polyamide fibre materials using reactive dyes

Reactive dyes of formula (1): wherein R, is optionally substituted C-Calkyl, Ris halogen, C-Calkyl, C-Calkoxy or sulfo, Zis a radical of formula &#x2014;SO&#x2014;Y (), &#x2014;CO&#x2014;NH&#x2014;(CH)&#x2014;SO&#x2014;Y (), &#x2014;NH&#x2014;CO&#x2014;CH(Hal)&#x2014;CH&#x2014;Hal () &#x2014;NH&#x2014;CO&#x2014;C(Hal)&#x2550;CHor () wherein Hal is chlorine or bromine, Y is vinyl or a radical &#x2014;CHCH&#x2014;U and U is a group removable under alkaline conditions, k is the number 2, 3, 4, 5 or 6, n is the number 0, 1 or 2 and m is the number 0 or 1, are suitable for dyeing or printing cellulose-containing fibre materials, preferably natural or synthetic polyamide fibre materials, and produce, with a high colour yield, dyeings and prints having good fastness properties 

Reactive dyes, a process for their preparation and their use

Method for the trichromatic dyeing or printing of synthetic polyamide fiber material, wherein at least one red reactive dye of formulais used together with at least one of the yellow or orange reactive dyes of formulaeand at least one blue reactive dye of formulain which formulaethe variables are as defined in claim 1,which method is distinguished by a uniform color build-up and a very good combinability.
