Abstract
Disazo dyestuffs of the formula (I) D1-N=N-A1-N(R')-R3-Z-R4-N(R2)-A2-N=N-D2 (D1 and D2 = residues of diazo components; R1 and R2 = H or alkyl; R3 and R4 = alkylene; A1 and A2 = p-phenylene; and Z = a colourless difunctional group pref. contg. at least one hetero atom, which when D1 and/or D2 contains a heterocyclic group and/or a quatermisable hetero atom, pref. is (1) free of ether or C-N-C linkages, and/or (2) is not a difunctional aliphatic hydrocarbyl group). (I) are used in finely divided form for dyeing all kinds of synthetic fibres. (I) contg. one or two quaterised diazo residues are esp. suitable for dyeing fibres of the polyacrylic type. Non-quaterised (I) are pref. applied by the thermofixing process. (I) are also useful for spin dyeing polyesters, polyamides and polyalkenes, and for pigmenting paints, plastics and resins.
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von wertvollen, neuen Disazofarbstoffen der Formel
EMI1.1
worin R1 und R2 je ein Wasserstoffatom oder vorzugsweise gegebenenfalls substituierte Alkylgruppen, R3 und R4 gegebenenfalls substituierte Alkylengruppen, welche die Stickstoffatome und Z über vorzugsweise mindestens 2 Kohlenstoffatome verbinden, Al und A2 je einen Naphthylen- oder Phenylenrest, welcher vorzugsweise keine Substituenten mit aktiven Wasserstoffatomen trägt, Dl und D2 je den Rest einer Diazokomponente, welcher vorzugsweise keine heterocyclischen Ringe und/oder keine quaternisierbaren Heteroatome enthält und Z ein vorzugsweise mindestens ein Heteroatom enthaltendes farbloses, zweiwertiges Brückenglied bedeuten, welche,
wenn Dl und/oder D2 eine heterocyclische Gruppe und/oder ein quaternisierbares Heteroatom enthält, vorzugsweise (1) frei von Aether- oder C-N-C-Bindungen ist und/oder (2) kein zweiwertiger Kohlenwasserstoffrest ist, welches dadurch gekennzeichnet ist, dass man die Azokomponenten der Formel wA1-NR1-R3-R4-NR2-A2-H
074 mit den Diazoniumverbindungen der Diazokomponenten Dl-NH2 und D2-NH2 zur Diazoverbindung kuppelt.
Der Naphthylen- oder Phenylenrest, den die Gruppen As und A2 darstellen, ist vorzugsweise in 1,4-Stellung gebunden.
Bei der Herstellung können sowohl gleiche Komponenten A, B, R1 und R2 sowie R3 und R4 verwendet werden, sodass man zu symmetrischen Disazofarbstoffen gelangt, als auch Ausgangsstoffe, worin eine oder mehrere dieser Komponenten verschieden voneinander sind, sodass man zu Mischungen von Disazofarbstoffen gelangt.
Die Diazoreste Dl und D2 sind aromatische Gruppen, welche vorzugsweise keine heterocyclischen Ringe und/oder keine quaternisierbaren Heteroatome enthalten.
Man verwendet als Diazokomponenten Dl-NH2 und D2-NH2 vorzugsweise Aminobenzole, insbesondere solche der Formel
EMI1.2
worin a ein Wasserstoff- oder Halogenatom, eine Alkyl- oder Alkoxy-, Nitro-, Cyan-, Carbalkoxy- oder Alkylsulfongruppe und b ein Wasserstoff- oder Halogenatom, eine Alkyl-, Cyanoder Trifluormethylgruppe bedeuten.
Als Beispiele seien genannt: Aminobenzol,

Die Reste Al und A2 der Azokomponente sind in 1,4 Stellung gebundene Naphthylen- und vor allem Phenylengruppen, die vorzugsweise keine alkylierbaren oder acylierbaren Hydroxy-, Mercapto- oder primäre und sekundäre Aminogruppen tragen.
Als Beispiele seien 1,4-Phenylengruppen der Formeln
EMI1.3
genannt, worin cl, c2, dl und d2 Wasserstoffatome, Methyl-, Aethyl-, Methoxy-, Aethoxy-, Phenylmercapto- oder Phenoxyreste sind.
Als farbloses Brückenglied Z kommen vor allem Gruppen der folgenden Formeln in Betracht:
EMI1.4
VR5+, worin Rs ein zweiwertiger aliphatischer, araliphatischer oder aromatischer Rest ist, dessen Kohlenstoffkette durch Heteroatome, insbesondere Sauerstoffatome, unterbrochen sein kann, vorzugsweise ein Rest der Formel
EMI2.1
und vor allem die Acylreste enthaltenden Gruppen der Formeln -OCO-, -OCOO-, -OCOCOO-, -NHCO-, -CONH-, -CONHCO-, -CONHNHCO-, -NHCOCONH-, sowie das farblose Bindeglied der Formel -x'CO-R6-COx'-, worin X' ein Sauerstoffatom, ein Schwefelatom oder eine -NH Gruppe ist und R6 ein aliphatischer, aromatischer oder heterocyclischer Rest, vorzugsweise ein Aethylen- oder ein p-, moder o-Phenylenrest ist,

wenn X' eine NH Gruppe ist, hat R8 die gleiche Bedeutung wie R,, und das farblose Bindeglied der Formel -X''SO2-Rg-SO2X'', worin X" ein Sauerstoffatom oder ein gegebenenfalls substituiertes Stickstoffatom und R9 ein aliphatischer oder aromatischer Rest ist.
Zur Einführung des Bindegliedes Z bzw. zur Herstellung der Kupplungskomponenten kann man wie folgt vorgehen, indem man zwei monofuktionelle Kupplungskomponenten der Formeln
EMI2.3
worin X, und X2 eine mindestens ein reaktives Wasserstoffatom enthaltende Gruppe, vorzugsweise eine Amino-, Mercapto- oder Hydroxylgruppe oder deren reaktionsfähige Derivate, darstellt, miteinander verknüpft.
Die Verknüpfung mit Dicarbonsäureestern erfolgt nach bekannten Methoden, z. B. durch Veresterung, insbesondere unter azeotropischer Wasserabspaltung, durch Umesterung unter Abspaltung eines flüchtigen Alkohols oder Phenols oder durch Umsetzung mit Dicarbonsäureanhydriden, durch Umsetzung mit Dicarbonsäurehalogeniden, wobei die in der Azokomponente vorhandene tertiäre Aminogruppe zur Aufnahme des freiwerdenden Halogenwasserstoffes dienen kann; neben den rein organischen Säurechloriden können auch die phosphororganischen Alkanphosphorsäuredichloride, wie Aethan- oder Cylohexanphosphorsäuredichlorid eingesetzt werden.
Zur Herstellung der Dicarbaminsäureester setzt man weiterhin, wenn die Gruppe X eine Hydroxylgruppe ist, mit Diisocyanaten um, wobei man vorzugsweise entweder in inerten Lösungsmitteln oder bohne Lösungsmittel bei mässigen Temperaturen arbeitet, jedoch auch aktive Lösungsmittel verwenden kann.
In die Klasse der organischen Säurechloride fällt weiterhin das Phosgen, mit welchem man die Carbonate erhält; man kann die Umsetzung so ausführen, dass man die Hydroxylgruppe der Farbstoffkomponente zunächst mit mindestens einem Mol
Phosgen zum Chlorkohlensäureester umsetzt und diesen an ein
Diol oder unsubstituiertes oder partiell substituiertes Diamin anlagert. Die Kohlensäureester kann man jedoch auch durch Umesterung mit Dialkyl- oder Diarylcarbonaten herstellen.
Wenn X eine Aminogruppe mit mindestens einem aktiven Wasserstoffatom ist, erhält man vorzugsweise durch Umsetzung mit Dicarbonsäurehalogeniden die entsprechenden Dicarbon säureamide, und bei Umsetzung mit Alkanphosphorsäuredichloriden die entsprechenden Phosphorsäurediamide. Durch
Umsetzung mit Diisocyanaten erhält man die entsprechenden Harnstoffe. Lässt man die Farbstoffkomponente mit einer äquimolaren Menge eines Bis-chlorkohlensäureesters reagie ren, so erhält man die entsprechenden Bis-carbaminsäureester.
Aus Ausgangsstoffe kommen, wenn Z der Rest einer Dicarbonsäure ist, als bifunktionelle Reaktionskomponenten für die Gruppe X die folgenden freien Säuren, deren Halogeni de und Anhydride (falls die Säure zur Anhydridbildung befähigt ist) oder deren Ester mit flüchtigen Alkoholen in

EMI3.1
Zur Verknüpfung mit dem Acylrest einer Disulfonsäure kommen die Halogenide aliphatischer und vor allem aromati scher Disulfonsäuren in Frage.
Als Diisocyanatkomponenten, die durch Umsetzung mit
2 Mol der Farbstoffkomponente der Formel D1-N=N- Al-NRl-R3-X das farblose Bindeglied Z bilden, eignen sich aliphatische, cycloaliphatische, araliphatische, aromatische oder heterocyclische Diisocyanate.

Diphenylsulfiddiisocyanat, sowie ihre Substitutionsprodukte, z.B. mit Alkyl-, Alkoxyl-, Halogenoder Nitrogruppen substituierte Derivate, wie z.B. 3,3'-Dimethyl- oder 3,3'-dimethoxy- oder 3,3'-Dichlor-diphenylmethan- 4,4'-diisocyanat. Auch Diisocyanate der Naphthalinreihe, wie Naphthylen-1,5-diisocyanat, oder heterocyclische Diisocyanate, z. B. des Benzofurans oder Harnstoff und Uretdiongruppen aufweisende Diisocyanate, wie 1,3-Bis-(4'methyl- 3'-isocynato-phenyl)-uretdion, seien als Beispiele genannt.
Bevorzugt werden symmetrische Diisocyanate, wie Diphenyl-4,4'- oder Diphenylmethan- 4,4'-diisocyanat eingesetzt.
Die Diisocyanate können gegebenenfalls auch in situ hergestellt werden, z.B. durch Umsetzung von Bis-chlormethylbenzolen und Natrium- oder Bleicyanat in aktiven Lösungsmitteln.
Zur Herstellung von Carbonaten kann man, wenn X eine Hydroxylgruppe ist, entweder direkt mit Phosgen, gegebenenfalls in Gegenwart quaternärer Ammoniumbasen oder -salze, zum Carbonat umsetzen, oder kann zunächst den Chlorameisensäureester eines Azofarbstoffrestes herstellen und entweder mit dem gleichen oder einem weiteren, eine freie Hydroxylgruppe enthaltenden Azofarbstoffrest zum Carbonat umsetzen.
Andererseits kann man 2 Mol des Chlorameisensäureesters, vorzugsweise in Gegenwart eines Chlorwasserstoff-Akzeptors wie Pyridin, mit einem Mol eines Diols, eines Diamins oder eines Dithiols zum Diurethan, Bis-(thiourethan) oder zur Bisharnstoffverbindung umsetzen.

EMI4.1
EMI5.1
Diamine der Formel H-A1-NR1-R3-Z2-R4-NR2-A2-H,
525 worin R1 und R2 Wasserstoffatome oder vorzugsweise gegebenenfalls substituierte Alkylgruppen, R3 und R4 gegebenenfalls substituierte Alkylengruppen, Z2 ein zweiwertiger Rest, der mindestens eine, vorzugsweise mindestens 2 Acylgruppen bzw.
einen Diacylrest als zweiwertige Gruppen in der Hauptkette enthält, welche die Stickstoffatome miteinander verbindet, und H-A1 und A2-H Phenylen- oder Naphthylenreste sind, werden gleichfalls beansprucht.
Diese Diamine erhält man, wenn man die oben beschriebenen Acylierungen mit bifunktionellen Verbindungen durchführt, wobei man jedoch statt einer Farbstoffkomponente die entsprechende Kupplungskomponenten der Formeln
EMI6.1
verwendet, worin H-A1, H-A2, Rl, R2, R3 und R4 die gleiche Bedeutung wie oben haben und X1 und X2 eine mindestens ein reaktives Wasserstoffatom enthaltende Gruppe, vorzugsweise eine Amino-, Mercapto oder Hydroxylgruppe darstellt.
Die neuen Farbstoffe, ihre Gemische untereinander und ihre Gemisch mit anderen Azofarbstoffen eignen sich ausgezeichnet, insbesondere nach Überführung in eine feinverteilte Form, z.B. durch Vermahlen, Verpasten, Umfällen etc. zum Färben und Bedrucken von synthetischen Fasern, beispielsweise aus Celluloseacetat, insbesondere aber aromatischen Polyestern. Man erhält darauf nach den üblichen Färbeverfahren, z.B. aus einer Färbeflotte, die eine feine Dispersion des Farbstoffes und zweckmässig ein Dispergiermittel enthält, bei Temperaturen nahe bei 100 C, gegebenenfalls unter Zugabe eines Quellmittels, oder bei Temperaturen über 100 C unter Anwendung von Überdruck, reine, kräftige Färbungen, die sich durch hervorragende Licht- und Sublimationsechtheit auszeichnen.
Die neuen Farbstoffe besitzen ausserdem den Vorzug, im Färbebad anwesende Wolle und andere Fasern nur wenig anzufärben. Sie sind daher gut geeignet zum Färben von Polyester-Wolle- oder z. B. Polyester-Triacetat-Mischungen.
Die erfindungsgemässen Farbstoffe eignen sich auch zum Färben nach dem sogenannten Thermosol-Verfahren, wonach das zu färbende Gut mit einer wässerigen Dispersion des Farbstoffes, welche zweckmässig 1 bis 50% Harnstoff und ein Verdickungsmittel, insbesondere Natriumalginat, enthält, vorzugsweise bei Temperaturen von höchstens 60 C imprägniert und wie üblich abgequetscht wird. Zweckmässig quetscht man so ab, dass die imprägnierte Ware 50 bis 100% ihres Ausgangsgewichtes an Färbeflüssigkeit zurückhält. Zur Fixierung des Farbstoffes wird das so imprägnierte Gewebe, zweckmässig nach vorheriger Trocknung, z.B. in einem warmen Luftstrom, auf Temperaturen von über 100 C, beispielsweise zwischen 180 und 210 C, erhitzt.
Von besonderem Interesse ist das eben erwähnte Thermosol-Verfahren zum Färben von Mischgeweben aus Polyesterfasern und Cellulosefasern, insbesondere Baumwolle. In diesem Fall enthält die Klotzflüssigkeit neben dem erfindungsgemässen Farbstoff noch zum Färben von Baumwolle geeignete Farbstoffe, beispielsweise Küpenfarbstoffe. Bei Verwendung letzterer ist eine Behandlung des foulardierten Gewebes nach der Hitzebehandlung mit einer wässerigalkalischen Lösung eines in der Küpenfärberei üblichen Reduktionsmittels nötig.
Die neuen Farbstoffe stellen zum Teil auch wertvolle Pigmente dar, welche für die verschiedensten Pigmentapplikationen verwendet werden können, z.B. in feinverteilter Form zum Färben von Kunstseide und Viskose oder Celluloseäthern und -estern oder von Superpolyamiden bzw. Superpolyurethanen oder Polyestern in der Spinnmasse, sowie zur Herstellung von gefärbten Lacken oder Lackbildnern, Lösungen und Produkten aus Acetylcellulose, Nitrocellulose, natürlichen Harzen oder Kunstharzen, wie Polymerisationsharzen oder Kondensationsharzen, z.B. Aminoplasten, Alkydharzen, Phenoplasten, Polyolefinen, wie Polystyrol, Polyvinylchlorid, Polyäthylen, Polypropylen, Polyacrylnitril, Gummi, Casein, Silikon und Silikonharzen.
Als Mischungen von Disazo- und Monoazofarbstoffen seien auch solche erwähnt, die durch Kupplung der bifunktionellen Kupplungskomponente der Formel H-A1-NR1-R3-R4-NR2-A2-H mit weniger als 2 Mol einer Diazokomponente der Formel D-N = Nl erhalten werden.
In den nachfolgenden Beispielen bedeuten die Teile, sofern nichts anderes angegeben wird, Gewichtsteile, die Prozente Gewichtsprozente, und die Temperaturen sind in Celsiusgraden angegeben.

EMI2.3
wherein X and X2 represent a group containing at least one reactive hydrogen atom, preferably an amino, mercapto or hydroxyl group or their reactive derivatives, linked to one another.
The linkage with dicarboxylic acid esters is carried out by known methods, e.g. B. by esterification, especially with azeotropic elimination of water, by transesterification with elimination of a volatile alcohol or phenol or by reaction with dicarboxylic acid anhydrides, by reaction with dicarboxylic acid halides, the tertiary amino group present in the azo component being able to serve to absorb the hydrogen halide released; In addition to the purely organic acid chlorides, it is also possible to use the organophosphorus alkanephosphoric acid dichlorides, such as ethane or cyclohexanephosphoric acid dichloride.

These diamines are obtained when the acylations described above are carried out with bifunctional compounds, but instead of a dye component, the corresponding coupling components of the formulas are used
EMI6.1
used, where H-A1, H-A2, Rl, R2, R3 and R4 have the same meaning as above and X1 and X2 represent a group containing at least one reactive hydrogen atom, preferably an amino, mercapto or hydroxyl group.
The new dyes, their mixtures with one another and their mixture with other azo dyes are outstandingly suitable, especially after conversion into a finely divided form, e.g. by grinding, pasting, reprecipitation, etc. for dyeing and printing synthetic fibers, for example made of cellulose acetate, but especially aromatic polyesters. The usual dyeing processes, e.g. from a dye liquor which contains a fine dispersion of the dye and suitably a dispersant, at temperatures close to 100 ° C., optionally with the addition of a swelling agent, or at temperatures above 100 ° C. with the use of excess pressure, pure, strong colorations that are distinguished by excellent light - and sublimation fastness.
The new dyes also have the advantage of only slightly staining wool and other fibers in the dyebath. They are therefore well suited for dyeing polyester wool or z. B. polyester-triacetate mixtures.
The dyes according to the invention are also suitable for dyeing by the so-called thermosol process, according to which the material to be dyed with an aqueous dispersion of the dye, which advantageously contains 1 to 50% urea and a thickener, especially sodium alginate, preferably at temperatures of at most 60 ° C is impregnated and squeezed off as usual. It is advisable to squeeze in such a way that the impregnated goods retain 50 to 100% of their initial weight in dyeing liquid. In order to fix the dye, the fabric impregnated in this way is expediently dried, e.g. in a warm air stream, heated to temperatures of over 100 C, for example between 180 and 210 C.
The just mentioned thermosol process for dyeing blended fabrics made of polyester fibers and cellulose fibers, in particular cotton, is of particular interest. In this case, in addition to the dye according to the invention, the padding liquid also contains dyes suitable for dyeing cotton, for example vat dyes. If the latter is used, the padded fabric must be treated after the heat treatment with an aqueous alkaline solution of a reducing agent customary in vat dyeing.
Some of the new dyes are also valuable pigments which can be used for a wide variety of pigment applications, e.g. in finely divided form for dyeing rayon and rayon or cellulose ethers and esters or superpolyamides or super-polyurethanes or polyesters in the spinning mass, as well as for the production of colored lacquers or lacquer formers, solutions and products made from acetyl cellulose, nitrocellulose, natural resins or synthetic resins such as polymerization resins or condensation resins, e.g. Aminoplasts, alkyd resins, phenoplasts, polyolefins such as polystyrene, polyvinyl chloride, polyethylene, polypropylene, polyacrylonitrile, rubber, casein, silicone and silicone resins.
Mixtures of disazo and monoazo dyes that may be mentioned are those obtained by coupling the bifunctional coupling component of the formula H-A1-NR1-R3-R4-NR2-A2-H with less than 2 mol of a diazo component of the formula D-N = Nl.

This dye preparation is stirred with 40 parts of a 10% strength aqueous solution of the sodium salt of N-benzyl-γ-heptadecyl-benzimidazole disulfonic acid and 4 parts of a 40% strength acetic acid solution are added. A dyebath of 4000 parts is prepared from it by diluting it with water.
100 parts of a cleaned polyester fiber material are added to this bath at 50 ", the temperature is increased to 120 to 130" within half an hour and dyed for one hour in a closed vessel at this temperature.
It is then rinsed well. A strong, pure, burgundy-red dyeing of excellent lightfastness and sublimation fastness is obtained.
