Red-dyeing dye mixtures of water-soluble fiber-reactive azo dyes and

Dye intermediates

A dye mixture comprising one or more disazo dyes composed of 1-amino-3,6-disulfo-8-naphthol as the coupling component and of two diazo components of the aniline series containing each a fiber-reactive group of the vinylsulfone series, one or more monoazo dyes composed of a carboxy-substituted benzoylamino-sulfo-naphthol coupling component and a diazo component of the aniline series, containing a fiber-reactive group of the vinylsulfone series and optionally one or two monoazo dyes with 1-amino-3,6-disulfo-8-naphthol as a coupling component to which is coupled in the ortho-position to the amino group a diazo component of the aniline series substituted by a fiber-reactive group of the vinylsulfone series. The dye mixtures yield on hydroxy- and/or carboxamido-containing fiber materials, such as cellulose fibers, in particular cotton, or on, for example, wool and synthetic polyamide fibers, deep black dyeings.

Deep black dye mixtures of fiber-reactive azo dyes and use thereof for

The present invention concerns orange dye mixtures of fiber-reactive azo dyes, suitable for dyeing hydroxy- and/or carboxamido-containing material, such as cellulose fibers, like cotton, or wool and nylon, 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## in which D.sub.1 and D.sub.2 are each, independently from one another, a radical of a benzene or naphthalene nucleus, R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each, independently from one another, hydrogen, methyl, ethyl, methoxy, ethoxy, sulfo or carboxy, M is hydrogen or an alkali metal and the groups Y.sub.1 --SO.sub.2 -- and Y.sub.2 --SO.sub.2 -- are each fiber reactive groups of the vinylsulfone series.

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

Fiber-reactive monoazo and disazo dyes, suitable for dyeing cellulose material, such as cotton, and also synthetic or natural polyamide material, such as wool, in high color depth and with good fastness properties, are described which contain a quaternary ammonium group, such as a trialkylammonium group, and contain, as a fiber-reactive group, a group of the vinyl-sulfone series, or a grouping containing a group of the vinyl-sulfone series, or a heterocyclic fiber-reactive group selected from a halogeno-substituted pyrimidine or triazine.

A fiber-reactive dye corresponding to formula (1) ##STR1## in which: Fb is the radical of an azo dye, of a heavy metal complex azo dye, of a formazan dye, of a triphenodioxazine dye or of a phthalocyanine dye;

Reactive dyes containing a permanent quaternary ammonium group

A fiber reactive dye having the formula ##STR1## wherein R.sub.1 and R.sub.3 are independently selected from the group consisting of; hydrogen; an alkyl group having from one to four carbon atoms; the foregoing alkyl group further substituted with one or more groups selected from hydroxy; amino; sulfo; halogen; an aryl radical; a heterocyclic radical or combination thereof; where for R.sub.3 said amino group maybe further substituted by a nitrogen heterocyclic fiber reactive group of the series: 1, 3, 5 mono or dichloro triazinyl; 1, 3, 5 mono or difluoro triazinyl; trichloropyrimidinyl; difluoropyrimidinyl; or monochlorodifluoro pyrimidinyl; where the nitrogen heterocycle may be further substituted by an: alkyl; or aryl amino group; wherein B is selected from the group consisting of a C.sub.2 to C.sub.4 alkyl chain; a substituted aryl or a heterocyclic radical; wherein X is selected from the group consisting of SO.sub.3 H; SO.sub.3 Na or a hydroxy group; and wherein Q.sub.1 and Q.sub.2 are independently selected from diazo components.

Bis-pyridone compounds

Novel sulfonated quinolone compounds used in the preparation of fiber reactive dyes having the formula: ##STR1## being N-alkyl substituted-4-hydroxy-6-sulfo-2-quinolone. The alkyl group bonded to the nitrogen in the quinolone has from 1 to 4 carbon atoms which may be further substituted by an hydroxy, amino, or sulfo group. The compounds of the invention may be prepared by the sulfonation of an N-alkyl substituted-4-hydroxy-2-quinolones, ##STR2## followed by selective desulfonation to yield the compounds of interest. New monoazo fiber reactive dyes having the formulas: ##STR3## and their metal complexes, may be prepared from these sulfonated compounds by the diazotization of an amine component, selected from an unsubstituted, or a substituted benzene or naphthalene compound, containing a fiber reactive group, and coupling the diazo component to the compounds of the invention. These dyes are suitable for the dyeing and printing of native and synthetic carbonamide containing fibers, and native or regenerated or synthetic hydroxy containing fibers, especially on cellulose fibrous materials, in the presence of an alkaline agent.

Sulfonated quinolone compound and method of preparation

Fiber reactive dyes of the anthraquinone type which provide brilliant violet colors without metal complexing. These dyes may be represented by the formula: ##STR1## wherein W is selected from NR.sub.2 and oxygen; R is independently selected from hydrogen, C.sub.1 -C.sub.6 alkyl; C.sub.1 -C.sub.6 alkoxy, sulfo and carboxy; R.sub.1 is selected from hydrogen, C.sub.1 -C.sub.6 alkyl and phenyl; R.sub.2 is selected from hydrogen and C.sub.1 -C.sub.6 alkyl; R.sub.3 is selected from hydrogen, and C.sub.1 -C.sub.4 alkyl; n is an integer of 1 or 2; and Y is CH.dbd.CH.sub.2, or CH.sub.2 CH.sub.2 Z wherein Z is a group capable of being split off by the action of an alkali reagent.

Fiber reactive anthraquinone dyes

The invention is that of a water soluble fiber reactive anthraquinone blue dyes. These dyes may be used to dye and print textiles and other substrates containing hydroxy and or groups in brilliant blue colors. The dyes of the invention are free of heavy metals.
