Description
DEUTSCHESGERMAN
Gegenstand der Hauptpatentanmeldung ist ein photographisches Material, das aus einem Schichtträger und lichtempfindlichen Schichten und gegebenenfalls Zwischenschichten besteht, wobei der Schichtträger aus einem Polycarbonat auf der Grundlage von Di-monooxyarylalkanen, insbesondere von 4,4'-Di-(monooxyaryl)-alkanen besteht.Subject of the main patent application is a photographic material, which consists of a support and light-sensitive layers and optionally intermediate layers, wherein the support consists of a Polycarbonate based on di-monooxyarylalkanes, in particular 4,4'-di- (monooxyaryl) -alkanes consists.
In Weiterentwicklung dieses Gegenstandes wurde nun gefunden, daß man zu photographischen Materialien mit vorteilhaften Eigenschaften gelangt, wenn man in dem Schichtträger die genannten Polycarbonate ganz oder teilweise durch solche hochmolekulare thermoplastische Polymerisate ersetzt, die Gruppierungen enthalten, in denen das Kohlenstoffatom der Kohlensäure über ein Sauerstoffatom an einen aromatischen Kern gebunden ist.In a further development of this subject it has now been found that one can use photographic materials advantageous properties are obtained if the polycarbonates mentioned are wholly or in the layer support partially replaced by such high molecular weight thermoplastic polymers which contain groups in where the carbon atom of the carbonic acid is bound to an aromatic nucleus via an oxygen atom.
Derartige Polycarbonate sind beispielsweise solche auf Grundlage von Dioxy-diarylsulfonen oder Gemischen von Dioxy-diarylsulfonen mit anderen bifunktionellen Oxyverbindungen, wie sie nach dem Verfahren gemäß der deutschen Auslegeschrift 1 007 996 erhalten werden können.Such polycarbonates are, for example, those based on dioxy-diarylsulfones or mixtures of dioxy-diarylsulfones with other bifunctional oxy compounds, as they are according to the method the German Auslegeschrift 1 007 996 can be obtained.
Ferner seien die hochmolekularen Polycarbonate auf Grundlage von Dioxy-diaryläthern oder aus Dioxydiarylthioäthern, bzw. aus Gemischen einer oder mehrerer dieser Verbindungen mit anderen Dioxyverbindungen angeführt. Diese hochmolekularen Polycarbonate können nach dem Verfahren der belgischen Patentschrift 560 610 erhalten werden.Furthermore, the high molecular weight polycarbonates based on dioxy-diaryl ethers or from dioxydiarylthioethers, or from mixtures of one or more of these compounds with other dioxy compounds cited. These high molecular weight polycarbonates can be produced according to the method of Belgian patent specification 560 610 can be obtained.
Weiterhin kommen Polycarbonate aus Gemischen aus mindestens einer aliphatischen bzw. cycloaliphatischen Dioxyverbindung und mindestens einer aromatischen Dioxyverbindung, ausgenommen die oben angeführten aromatischen Dioxyverbindungen, in Frage, die nach dem Verfahren gemäß der deutschen Auslegeschrift 1 011 148 erhalten werden können.Furthermore, polycarbonates come from mixtures of at least one aliphatic or cycloaliphatic Dioxy compound and at least one aromatic dioxy compound other than those listed above aromatic dioxy compounds, in question, which according to the method according to the German Auslegeschrift 1 011 148 can be obtained.
Die Herstellung von Schichtträgern für photographische Materialien aus diesen Polycarbonaten kann nach dem Verfahren des Hauptpatentes erfolgen. Ferner können die auf diese Weise erhaltenen Schichtträger vor dem Aufbringen von lichtempfindlichen Schichten mit einer oder mehreren dünnenZwischenschichtenversehenwerden. Auch hierzu eignen sich die in der Hauptpatentanmeldung beschriebenen Verfahren.The production of supports for photographic Materials made from these polycarbonates can be made according to the method of the main patent. Furthermore can the layer support obtained in this way before the application of photosensitive layers with a or several thin intermediate layers. The methods described in the main patent application are also suitable for this purpose.
In den folgenden Beispielen sind die angeführten Teile Gewichtsteile.In the following examples the parts given are parts by weight.
Ein Polycarbonat, das durch Veresterung eines Gemisches von 96,3 Teilen 4,4'-Dioxydiphenyl-2,2-propan und 47,3 Teilen 4,4'-Dioxydiphenylsulfon mit Kohlensäure ii Form von Phosgen erhalten wurde (deutsche Auslegeschrift 1007 996) wird mit Methylenchlorid zu einer Lösung von 10000 bis 6000OcP Viskosität verarbeitet. Diese wird wie üblich filtriert, fuftfrei gemacht und auf Photographisches MaterialA polycarbonate that is produced by esterification of a mixture of 96.3 parts of 4,4'-dioxydiphenyl-2,2-propane and 47.3 parts of carbonated 4,4'-dioxydiphenylsulfone ii form of phosgene was obtained (German Auslegeschrift 1007 996) is processed with methylene chloride to a solution with a viscosity of 10,000 to 6,000 ocP.

Die Präparation geschieht nach einer der obengenannten Methoden.A polycarbonate is used as described in Belgian patent 560 610 (esterification of 109 parts of 4,4'-dioxydiphenyl sulfide and 112 g of 2,2- (4,4'-dioxydiphenyl) propane with phosgene). the Solution of this material in methylene chloride leads to a film of high mechanical strength and Process with practically complete dimensional accuracy. The preparation takes place according to one of the above Methods.
