The present invention relates to a dye mixture which comprises at least one dye of the general formula (I) and at least one dye of the general formula (II) in which D, D, W, W, Y, Y, Rto R, M, m and n are defined as indicated in claim 1, to processes for preparing them, to their use, and to inks comprising them for digital printing.

Mixtures of fiber-reactive azo dyes, their production and their use

Water-soluble fiber-reactive dyes, preparation thereof and use thereof Dye mixtures which include the dyes of the general formula (1) and dyes of the general formula (2):their preparation and their use for dyeing or printing hydroxyl- and/or carboxamido-containing material, preferably fiber material.

Dye mixture of water soluble fiber-reactive dyes, method for their production and the use thereof

Mixtures of fiber-reactive dyes, preparation thereof and use thereof for dyeing fiber materials

Disclosed are dye mixtures comprising yellow dyes of the formulae indicated and defined in claim 1 which are useful for dyeing hydroxyl- and/or carboxamido-containing material, especially fiber material, such as cellulose fibers, for example cotton and filament viscose, and wool and also synthetic polyamide fibers.

Yellow dye mixtures comprising water-soluble fiber-reactive azo dyes and use thereof

Dye mixtures comprising water-soluble fiber-reactive azo dyes, preparation thereof and use thereof

The present invention comprises a dye mixture comprising one or more, such as one, two or three, disazo dyes conforming to the general formula (1), one or more, such as one, two or three, dyes.

Dye mixtures of fiber-reactive azo dyes and use thereof for dyeing material containing hydroxy-and/or carboxamido groups

Described are dye mixtures comprising one or more azo dyes (1) and one or more azo dyes (2) or (3) or (2) and (3), all these azo dyes containing a 1-(halotriazinylamino)-3,6- or -4,6-disulfo-8-naphthol coupling component and the third substituent in the triazine moiety of (1) and similarly of (2) and of (3) being an optionally alkyl- and/or phenyl-substituted amino radical or heterocyclic radical and the diazo component in (1) containing a fiber-reactive group of the vinyl sulfone series and being an optionally alkyl- and/or alkoxy-substituted phenyl or optionally sulfo-substituted naphthyl radical, in (2) being an optionally alkyl-, alkoxy-, chlorine-, bromine-, sulfo- and/or carboxyl-substituted phenyl or optionally sulfo-substituted naphthyl radical and in (3) being a sulfophenyl radical which, attached via an amino group, possesses a fiber-reactive halopyrimidine radical or a halotriazine radical having a fiber-reactive group of the vinyl sulfone series. The dye mixtures are very useful for dyeing hydroxyl- and/or carboxamido-containing materials, especially fiber materials, in deep bluish to yellowish red shades.

Disclosed are dye mixtures comprising yellow dyes of the formulae indicated and defined in claim 1 which are useful for dyeing hydroxy- and/or carboxamido-containing material, especially fiber material, such as cellulose fibers, for example cotton and filament viscose, and wool and also synthetic polyamide fibers.

Dye mixtures of fiber-reactive azo dyes and their use

Described are dye mixtures comprising dyes containing a coupling component comprising a 1-(chlorotriazinyl)amino-3,6-disulfo-8-naphthol radical, the dye or dyes of the one group of dyes containing an optionally loweralkyl-, loweralkoxy-, halogen, sulfo- and/or carboxy-substituted phenylamino or naphthylamino radical attached to the chlorotriazine radical and possessing a diazo component comprising an optionally loweralkyl-, loweralkoxy-, sulfo- and/or carboxy-substituted phenyl radical which is substituted by a fiber-reactive group of the vinyl sulfone series, and the dye or dyes of the other group of dyes containing attached to the chlorotriazine radical a phenylamino radical whose phenyl is substituted by a fiber-reactive group of the vinyl sulfone series and may be substituted by lower alkyl, lower alkoxy, sulfo and/or carboxy, and possessing a diazo component comprising a radical of benzene or naphthalene which may in each case be optionally substituted by lower alkyl, lower alkoxy, halogen, sulfo and/Qr carboxy. The dye mixtures are useful for preparing a dyeings and prints on hydroxy and/or carboxamido-containing fiber material, for example cotton and viscose fibers, and also wool and synthetic polyamide fiber materials and afford strong fast dyeings having a red hue.

Dye mixture, process for it's preparation and use thereof

The present invention provides a mixture of dyes which comprise one or more monoazo dyestuffs corresponding to the general formula (1) and one or more monoazo dyestuffs corresponding to the formula (2) ##STR1## wherein R1, R2, R3, R4, R5, R6, Y.sub.1, Y.sub.2 and M are defined as given in claim 1, methods for preparing said dye mixtures and methods for dyeing hydroxy and/or carboxamido-containing materials using said dye mixtures.

Dye mixtures of fiber-reactive azo dyes and use thereof for dyeing

The present invention relates to dye mixtures comprising one or more azo dyes of the general formula (1) and one or more azo dyes of the general formula (2) ##STR1## where p is 1 or 2,

Dye mixture comprising water-soluble fiber-reactive azo dyes,

The present invention comprises a dye mixture comprising one or more, such as one, two or three, disazo dyes conforming to the general formula (1), one or more, such as one, two or three, monoazo dyes conforming to the general formula (2), and one or more, such as one, two or three dyes of the general formulae (3) and (4) wherein the formulae (1) to (4) are defined as given in claim 1, a method for its preparation and a process for dyeing hydroxy- and/or carboxamido containing fiber material in which a inventive dye is applied to the material.

Black dye mixtures of fiber-reactive azo dyes and use thereof for dyeing

Process for reacting fluorine-substituted heterocycles with amines in the presence of phase transfer catalysts The reaction of an amino compound with a fluorine-substituted triazine or pyrimidine group is carried out in the presence of a phase transfer catalyst, preferably of the formula (4a), (4b) or (4c) ##STR1## where R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are identical or different and are each alkyl having from 1 to 20 carbon atoms which may be substituted by phenyl, or are phenyl.
