Description
Herstellung nichtrollender Filme. Bekanntlich haben photographische Filme die unangenehme Eigenschaft, sich nach der Schichtseite einzurollen, wodurch sich die Arbeit mit solchen Filmen äußerst schwierig gestaltet.Manufacture of non-rolling films. It is well known that photographic Films have the uncomfortable property of curling up after the layer side, which causes working with such films is extremely difficult.
Von den bekannten Verfahren zur Herstellung nichtrollender Filme hat ein Auftrag von Gelatine auf die Rückseite der Folie den Nachteil, daß der Film, besonders im feuchten Zustand, auch auf der Rückseite gegen Verletzung empfindlich ist. Diesen Nachteil vermeidet das Verfahren gemäß der Erfindung.Of the known processes for the production of non-rolling films an application of gelatin to the back of the film has the disadvantage that the film, especially when wet, also sensitive to injury on the back is. The method according to the invention avoids this disadvantage.
Es besteht darin, daß auf die Rückseite der Filmfolie aus Zelluloid o. dgl. eine Lösung von Harzen oder harzähnlichen Stoffen, die mit flüchtigen Lösungsmitteln eine Art Lack bilden, z. B. Schellack in Alkohol, in der übliehen Weise aufgetragen wird. Hierdurch entsteht ein nach dem Auftrocknen nicht erkennbarer und vollkommen durchsichtiger, farbloser Überzug, der der Folie die Eigenschaft erteilt, nach dem Emulsionieren und Trocknen eben zu liegen, auch während ünd nach dem ganzen Hervorrufungsprozeß nicht zu rollen, ohne daß der Film auf seiner präparierten Rückseite andere Eigenschaften aufweist wie der Folienstoff selbst.It consists in that on the back of the film sheet made of celluloid o. The like. A solution of resins or resin-like substances with volatile solvents form a kind of varnish, e.g. B. Shellac in alcohol, applied in the usual way will. This creates a color that is not recognizable and complete after it has dried out transparent, colorless coating, which gives the film the property after Emulsifying and drying to lie flat, even during and after the whole evoking process not to roll without the film having other properties on its prepared reverse side like the film itself.
Die für die Präparation zu --verwendende Art des Harzes, der Lösungsmittel wie der Konzentration der Lösung .ist .den verschiedenen Folienarten anzupassen.The type of resin to be used for the preparation, the solvent such as the concentration of the solution. is. to be adapted to the different types of film.
