Water-soluble fiber-reactive dyes, processes for their preparation, and

Dyes containing a 5,6-difluoropyrimidin-4-yl radical as fiber-reactive group are useful for dyeing hydroxy- and/or carboxamido-containing material, including fiber material, for example cellulose fibers, wool and polyamide.

Water-soluble fiber-reactive dyes, preparation thereof and use thereof

Process for dyeing or printing fiber materials containing hydroxyl groups, characterized in that at least one blue-dyeing dyestuff of the formula ##STR1## wherein the substituents have the meaning given in the description, is used together with at least one yellow-dyeing and/or at least one red-dyeing and/or at least one navy blue- or black-dyeing dyestuff.

Process for dyeing or printing fibre materials containing hydroxyl groups

Fiber-reactive azo dyes, processes for their preparation and their use Azo dyes of the formula (1) given and defined below are described, which dyes contain fiber-reactive groups and dye hydroxy- and/or carboxamido-containing materials, in particular fiber materials, such as cotton, wool and synthetic polyamide fibers, in shades of high color strength and good fastness properties. ##STR1## in which D is the radical of a diazo component from the benzene or naphthalene series, K is the radical of a coupling component of the formula (2) ##STR2## in which M is hydrogen or an alkali metal, a and b are each zero or 1, R.sup.1 and R.sup.2 are each hydrogen or substituted or unsubstituted alkyl, Y is attached to --NR.sup.1 -- or --NR.sup.2 -- and is a radical of the formula (3) ##STR3## in which R is hydrogen, substituted or unsubstituted alkyl or substituted or unsubstituted phenyl, A is the radical of an amine or of an N-containing heterocycle, lower alkoxy or phenoxy, c is zero or 1, G is substituted or unsubstituted phenylene, B is lower alkylene or ethyleneoxyethylene and the group --SO.sub.2 --X is .beta.-hydroxyethylsulfonyl or a fiber-reactive group from the vinylsulfone series and Z is a heterocyclic fiber-reactive radical which is attached to --NR.sup.1 -- or --NR.sup.2 -- and is different from Y.

Triazinyl-substituted fiber-reactive azo dyes wherein the triazinyl
