für ein Patent auf Hydrophile Beschichtungenfor a patent on hydrophilic coatings
Die Erfindung betrifft hydrophile Beschichtungen auf hydrophoben Unterlagen.The invention relates to hydrophilic coatings on hydrophobic substrates.
Es 1st bekannt, hydrophobe Unterlagen durch chemischen Angriff und durch Aufbringen Mehrerer Schichten zu modifizieren und gegenüber hydrophilen Beschichtungen verbundfähig zu machen. Sq wird z.B. Celluloseacetatfilm oberflächlich verseift, um die Oberfläche hydrophil zu machen, so daß die transparente Unterlage mit wäßrigen Lösungen beschichtet werden kann. Dieser Verseifungsprozeß hat jedoch den Nachteil, daß er nicht immer zuverlässig und sehr zeitraubend ist und außerdem eine komplizierte Apparatur erforderlich macht.It is known to add hydrophobic substrates by chemical attack and by applying multiple layers modify and oppose hydrophilic coatings to make connectable. For example, Sq becomes cellulose acetate film saponified on the surface to make the surface hydrophilic, so that the transparent base can be coated with aqueous solutions. However, this saponification process has the disadvantage that it does not is always reliable and very time consuming and also requires complicated apparatus.

Es ist weiterhin bekannt, hydrophobe Unterlagen mit hydrophilen Schichten in der Weise zu versehen, daß man auf die Unterlage mehrere Lagen von Vorbeschichtungen aufbringt, deren Hydrophilie allmählich zunimmt, bis schließlich eine wasserempfindliche Schicht gebildet wird. Dabei muß die letzte Schicht gut auf den darunterliegenden Schichten haften. Dieses Verfahren ist wegen der Vielzahl der auszuführenden BeSchichtungsvorgänge unwirtschaftlich und außerdem nicht vollständig zuverlässig, da es leicht vorkommt, daß eine oder mehrere der Zwischenlagen unzureichend haften. Bei vielen Unterlagen ist es schwierig, die erste Schicht mit ausreichender Haftung aufzubringen.It is also known to provide hydrophobic substrates with hydrophilic layers in such a way that one applies several layers of precoat to the substrate, the hydrophilicity of which gradually increases until eventually a water-sensitive layer is formed. The last layer has to be on top of the one below Layers adhere. This method is uneconomical because of the large number of coating processes to be carried out and also not completely reliable, since it is easy for one or more of the spacers to be insufficient be liable. With many substrates it is difficult to apply the first layer with sufficient adhesion.
Bs war die Aufgabe der vorliegenden Erfindung, Beschichtungsmassen für hydrophobe Unterlagen vorzusehen, die in einfacher Weise aufgebracht werden können und die eine gute Haftung auf der Unterlage besitzen.The object of the present invention was to provide coating compositions to be provided for hydrophobic substrates, which can be applied in a simple manner and which are good Have liability on the document.
Gegenstand der Erfindung sind hydrophile Beschichtungsmassen für hydrophobe Unterlagen, die dadurch gekennzeichnet sind, daß sie zwei filmbildende Harze enthalten, von denen das eine aus dem gleichen oder einem ähnlichen Polymeren wie die zu beschichtende Unterlage und das andere aua Poly-N-vinylpyrrolidon besteht.The invention relates to hydrophilic coating compositions for hydrophobic substrates, which are characterized in that they contain two film-forming resins, of which one made of the same or a similar polymer as the substrate to be coated and the other aua Poly-N-vinylpyrrolidone consists.

In der Beschichtungsmasse kann das Verhältnis von Harz zu Poly-N-vinylpyrrolidon zwischen 1:1 und 10:1 variiert werden.In the coating composition, the ratio of resin to Poly-N-vinylpyrrolidone can be varied between 1: 1 and 10: 1.
Bin weiterer Gegenstand der Erfindung ist ein Verfahren zum Aufbringen einer hydrophilen Schicht auf einen hydrophoben Träger durch Auftragen einer Lösung der die Beschichtung bildenden Komponenten und Verdampfen des Lösungsmittels, das dadurch gekennzeichnet ist, daß die Be-•chichtungslösung zwei filebildende Harze enthält, von denen das eine aus den gleichen oder einem ähnlichen Polymeren wie die zu beschichtende Unterlage und das andere aus Poly-N-vinylpyrrolidon besteht. Zur Durchführung des Verfahrens können die üblichen Antragsvorrichtungen verwendet werden. Der Peststoffgehalt der Beschichtungslösung kann zwischen 1 und 7 % liegen.The invention also relates to a method for applying a hydrophilic layer to a hydrophobic carrier by applying a solution of the components forming the coating and evaporating the solvent, which is characterized in that the coating solution contains two file-forming resins, of which the one consists of the same or a similar polymer as the substrate to be coated and the other of poly-N-vinylpyrrolidone. The usual application devices can be used to carry out the procedure. The pesticide content of the coating solution can be between 1 and 7 % .
Bine Variante der Erfindung besteht darin, daß man der Beschichtung Pigmente, beispielsweise feinverteiltes SiO9 und/oder Farbstoffe zusetzt, wenn eine mattierte und/oder gefärbte Beschichtung gewünscht wird.A variant of the invention consists in adding pigments, for example finely divided SiO 9 and / or dyes, to the coating if a matt and / or colored coating is desired.

Die hydrophile Schicht ist wasserempfindlich, aber nicht ohne weiteres in Wasser löslich. Die erfindungsgemäß beschichteten Materialien können gewerblich ../$ verwertet werden bei der Herstellung lichtempfindlicher Materialien, wobei auf die erfindungsgemäße hydrophile Schicht noch eine lichtempfindliche Schicht aufzubringen ist. Beispielsweise kann die erfindungsgemäß beschichtete Unterlage mit besonderem Vorteil verwendet werden zur Herstellung von Diazoschichten für das sogenannte Halbfeuchtverfahren sowie zur Herstellung von Druckplatten und &uf ähnlichen Anwendungsgebieten, wo eine hydrophile Oberfläche auf einer hydrophoben Unterlage gewünscht wird.Adhesion to the hydrophobic base and make these are suitable for further coating with aqueous solutions. The hydrophilic layer is sensitive to water, but not readily soluble in water. According to the invention coated materials can be used commercially ../$ are used in the production of photosensitive materials, with the hydrophilic according to the invention Layer to apply a light-sensitive layer is. For example, the coated according to the invention Underlay can be used with particular advantage for the production of diazo layers for the so-called semi-wet process as well as for the production of printing plates and uf similar fields of application where a hydrophilic surface on a hydrophobic base is desired.
Der besondere Vorteil der Erfindung gegenüber dem Stand der Technik besteht darin, daß auf einfache Weise ohne komplizierte App'araturen ausgezeichnet haftende hydrophile Schichten auf hydrophoben Unterlagen hergestellt werden können, wobei die Unterlage nicht unbedingt aus Celluloseacetat oder einem Celluloseacetatlaminat bestehen muß. Es ist weiterhin vorteilhaft, daß während des erfindungs-The particular advantage of the invention over the prior art is that in a simple manner without Complicated apparatuses, hydrophilic layers with excellent adhesion can be produced on hydrophobic substrates can, wherein the base does not necessarily have to consist of cellulose acetate or a cellulose acetate laminate. It is also advantageous that during the invention
