Description

Bei der Benutzung von Filmen ergebenSurrendered when using films

sich häufig Schwierigkeiten dadurch, daß selbst kleine Schrammen des Films einen Teil des Silberbildes zerstören, welches nicht wieder ausgebessert werden kann. Derartige Schrammen sind insbesondere nachteilig, wenn sie bei Tonbildfilmen vorkommen, da sie, falls die Tonaufzeichnungen getroffen werden, störende Nebengeräusche bei der Tonwiedergabe erzeugen.difficulties often arise from the fact that even small scratches on the film one Destroy part of the silver image that cannot be touched up again. Such Scratches are particularly disadvantageous when they occur in sound-image films, there they, if the sound recordings are hit, annoying background noises in the Generate sound reproduction.

Der Zweck der Erfindung ist, diesen Nachteil zu beseitigen, und zwar dadurch, daß das Silberbild durch eine Gelatineschicht geschützt wird.The purpose of the invention is to eliminate this disadvantage, namely in that the Silver image is protected by a gelatin layer.

Der angestrebte Zweck wird erfindungsgemäß erreicht durch Anwendung des Verfahrens, bei dem photographische Abbildungen durch den Emulsionsträger hindurch erzeugt werden, zum Herstellen von Tonbildfilmen. The intended purpose is achieved according to the invention by using the method in which photographic images are produced through the emulsion carrier for the production of sound image films.

Es ist bekannt, beispielsweise zur Beseitigung des Kornes einen Film durch den Schichtträger hindurch zu belichten.It is known, for example, to remove the grain through a film To expose layer support through.

Die Erfindung besteht in der Anwendung der gleichen Arbeitsweise zum Herstellen von ■Tonbildfilmen zu dem oben angegebenem Zweck.The invention consists in using the same procedure to manufacture ■ Sound-image films for the purposes set out above.

Der Emulsion wird dabei zweckmäßig ein Farbstoff, beispielsweise ein gelber Farbstoff, zugesetzt, welcher Licht derjenigen Wellenlängen absorbiert, für welches die Emulsion hauptsächlich empfindlich ist, wodurch erreicht wird, daß das Bild nicht die ganze Schicht durchsetzt, sondern nur in der Nähe des Schichtträgers erzeugt und demgemäß durch die Gelatineschicht geschützt wird.The emulsion is expediently a dye, for example a yellow dye, added, which absorbs light of those wavelengths for which the emulsion is mainly sensitive, which means that the picture is not the whole Layer penetrated, but only generated in the vicinity of the layer support and accordingly is protected by the gelatin layer.

Gemäß einer anderen Ausführungsweise kann der Emulsion ein beliebiger Farbstoff einverleibt werden, wobei dann das Kopierlicht dem Verwendung findenden Farbstoff angepaßt werden muß.In another embodiment, the emulsion can contain any dye are incorporated, in which case the copying light is then used in the dye must be adjusted.
