Description

Die Erfindung betrifft neue Benzophenonether-ester und ein Verfahren zum Färben von textilem Polyestermaterial mit Dispersionsfarbstoffen unter Verwendung von Benzophenonether-estern zur Verbesserung der Lichtechtheit sowie die Verwendung dieser Benzonphenon-derivate beim Färben von textilem Polyestermaterial.The invention relates to new benzophenone ether esters and a process for dyeing textile polyester material with disperse dyes using benzophenone ether esters to improve lightfastness, and to the use of these benzonphenone derivatives in dyeing textile polyester material.

Aus der DE-AS 1 156 760 ist beispielsweise ein Verfahren zur Verbesserung der Lichtechtheit von Polyesterfärbungen bekannt, bei dem man die Fasern in einem siedenden wäßrigen Färbebad, das neben dem Farbstoff noch Alkylether des 2,2',4,4'-Tetrahydroxybenzophenons enthält, behandelt. Bei diesem Verfahren zieht das Benzophenon-Derivat zusammen mit dem Farbstoff auf die Faser auf. Die so gefärbte Faser weist bei der Belichtung in einem Belichtungsgerät (beispielsweise Xenotest oder Fadeometer) eine im Vergleich zu einer ohne Zusatz des Tetrahydroxybenzophenon-Derivats gefärbten Faser bessere Lichtechtheit auf.DE-AS 1 156 760, for example, discloses a process for improving the light fastness of polyester dyeings, in which the fibers are in a boiling aqueous dye bath which, in addition to the dye, also contains alkyl ethers of 2,2 ', 4,4'-tetrahydroxybenzophenone , treated. In this process, the benzophenone derivative is drawn onto the fiber together with the dye. The fiber dyed in this way has better lightfastness when exposed in an exposure device (for example a Xenotest or fadeometer) compared to a fiber dyed without the addition of the tetrahydroxybenzophenone derivative.

Die in der DE-AS 1 156 760 beschriebenen Verbindungen weisen jedoch eine Reihe von Nachteilen auf: aufgrund ihrer Eigenfarbe verschieben sie insbesondere bei brillanten Färbungen der Farbton und trüben die Färbung mehr oder weniger stark ab. Das Aufziehvermögen auf die textilen Gebilde ist nicht erschöpfend genug, so daß das Abwasser der Färbereien mit organischen Verbindungen belastet wird. Außerdem neigen die genannten Verbindungen bei einer im Anschluß an den Färbeprozess üblicherweise durchgeführten thermischen Nachbehandlung zur Sublimation.However, the compounds described in DE-AS 1 156 760 have a number of disadvantages: due to their inherent color, they shift the color tone, in particular in the case of brilliant colorations, and cloud the coloration to a greater or lesser extent. The absorption capacity on the textile structures is not exhaustive enough, so that the wastewater from the dyeing plants is contaminated with organic compounds. In addition, the compounds mentioned tend to sublimation in a thermal aftertreatment usually carried out after the dyeing process.

Aus der US-PS 3 676 471 ist bekannt, daß 2,4-Dihydroxibenzophenon-Derivate als Lichtstabilisatoren von Kunststoffen, Polymeren wie z.B. Polypropylen, Polyvinylchlorid, Polyester oder Polyamide verwendet werden können. Es hat daraus nicht nahe gelegen, derartige Verbindungen in einem System aus Farbstoffen und textilem Polyestermaterial zur Stabilisierung der Farbstoffe einzusetzen.From US-PS 3,676,471 it is known that 2,4-dihydroxibenzophenone derivatives as light stabilizers of plastics, polymers such as e.g. Polypropylene, polyvinyl chloride, polyester or polyamides can be used. It was therefore not obvious to use such compounds in a system of dyes and textile polyester material to stabilize the dyes.

Aufgabe der Erfindung ist es, für die Verbesserung der Lichtechtheit von Färbungen mit Dispersionsfarbstoffen auf Polyester Stoffe zur Verfügung zu stellen, die gut auf Polyester aufziehen, eine geringe Sublimationstendenz zeigen und die die Färbungen insbesondere hinsichtlich ihrer Brillanz nicht oder nur geringfügig beeinträchtigen.The object of the invention is to provide materials for the improvement of the light fastness of dyeings with disperse dyes on polyester, which are good for polyester, show a low tendency to sublimation and which do not or only slightly impair the dyeings, in particular with regard to their brilliance.

Die Aufgabe wird erfindungsgemäß gelöst mit einem Verfahren zum Färben von textilem Polyestermaterial mit Dispersionsfarbstoffen unter gleichzeitiger Verwendung von Benzophenonderivaten zur Verbesserung der Lichtechtheit, das dadurch gekennzeichnet ist, daß man den Färbebädern ein Benzophenonderivat der Formel I

Nach dem erfindungsgemäßen Verfahren werden in an sich üblicher Weise textile Materialien aus Polyestern, insbesondere aus Polyethylenterephthalaten, wie Polyethylenglykolterephthalat, gefärbt. Als solche kommen insbesondere Gebilde wie Fasern, Fäden, Flocken, Folien, Gewebe und Gewirke in Betracht. Sie können mit den üblichen Dispersionsfarbstoffen, die den bekannten Farbstoffklassen wie z.B. Azo, Anthrachinon-, Methin-, Chinophthalon- und Cumarin-Farbstoffen, angehören, nach an sich bekannten Methoden, wie z.B. das Hochtemperaturverfahren, das Thermosolverfahren oder das Carrierfärbeverfahren, gefärbt werden, wie z.B. dem "Ratgeber, Färben und Ausrüsten von Polyesterfasern und Polyesterfasermischungen", herausgegeben von der BASF Aktiengesellschaft 1974, entnommen werden kann. Bei dem erfindungsgemäßen Verfahren werden die Benzophenon-Derivate den Färbebädern in feinverteilter Form ggf. als Pulver- oder Flüssigzubereitung zugesetzt. Sie werden in Mengen von 0,1 bis 10, vorzugsweise 0,3 bis 5 Gew.%, bezogen auf das Textilgut, eingesetzt.According to the method according to the invention, textile materials made from polyesters, in particular from polyethylene terephthalates, such as polyethylene glycol terephthalate, are dyed in a conventional manner. In particular, structures such as fibers, threads, flakes, foils, fabrics and knitted fabrics come into consideration as such. You can with the usual disperse dyes, the known dye classes such as Azo, anthraquinone, methine, quinophthalone and coumarin dyes belong, according to methods known per se, such as e.g. the high temperature process, the thermosol process or the carrier dyeing process are colored, e.g. can be found in the "Advice, dyeing and finishing of polyester fibers and polyester fiber mixtures", published by BASF Aktiengesellschaft 1974. In the process according to the invention, the benzophenone derivatives are added to the dyebaths in finely divided form, optionally as a powder or liquid preparation. They are used in amounts of 0.1 to 10, preferably 0.3 to 5% by weight, based on the textile material.

Man erhält dabei Färbungen, die im Vergleich zu solchen ohne Zusatz der Benzophenon-Derivate sich im Farbton nicht oder kaum unterscheiden, aber eine deutlich verbesserte Lichtechtheit aufweisen, die auch höheren Anforderungen, wie sie z.B. im Automobilsektor für Sitzbezüge und dergleichen gestellt werden, gerecht werden können.This gives dyeings which, in comparison to those without the addition of the benzophenone derivatives, have little or no difference in color, but have a significantly improved light fastness which also meets higher requirements, such as be provided in the automotive sector for seat covers and the like.

Als besondere Vorteile gegenüber bekannten Benzophenonderivaten gemäß der DE-AS 11 56 760 seien hervorgehoben, daß die erfindungsgemäß zu verwendenden Verbindungen eine deutlich geringere Eigenfarbe aufweisen und damit den Farbton von Färbungen praktisch nicht beeinflussen. Während z.B. das 2,2'-Dihydroxy-4,4'-dimethoxybenzophenon im Färbebad zu etwa 75 % auszieht, erreichen die erfindungsgemäß zu verwendenden Verbindungen Aufziehgrade in der Größenordnung von 85 bis 95 %. Bei den bekannten Verbindungen liegen die Sublimsationsverluste (30 sec., 190° C) bei 20 bis 25 %, bezogen auf die aufgezogene Substanz, bei den erfindungsgemäß zu verwendenden Verbindungen unterhalb 10 %.As a particular advantage over known benzophenone derivatives according to DE-AS 11 56 760, it should be emphasized that the compounds to be used according to the invention have a significantly lower intrinsic color and thus practically do not influence the hue of dyeings. While e.g. 75% of the 2,2'-dihydroxy-4,4'-dimethoxybenzophenone in the dyebath drains, the compounds to be used according to the invention reach degrees of absorption in the order of 85 to 95%. In the known compounds, the sublimation losses (30 sec., 190 ° C.) are 20 to 25%, based on the absorbed substance, in the compounds to be used according to the invention below 10%.
