KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die Nitrocellulose hat in letzter Zeit eine vielfache technische Anwendung gefunden, insbesondere interessiert für den vorliegenden Fall die Verwendung derselben für Films zu photographischen Zwecken. Die reine Nitrocellulose, welche gewöhnlich in Lösungen mit Alkohol, Äther, Aceton, Holzgeist und dergl. aufgetragen wird, gibt an und für sich eine zu spröde Schicht, so daß der Zusatz von Harzen, Ölen. Kampfer und dergl. erforderlich ist, um diese Schicht geschmeidig zu machen. Für photographische Zwecke bilden diese gebräuchlichen Zusätze einen Übelstand, weil die Harze oder Öle auf die auf die Häute aufgetragene Emulsionsschicht zersetzend wirken.Nitrocellulose has recently found a wide variety of technical applications, in particular interested in the present case the use of the same for film to photographic Purposes. The pure nitrocellulose, which is usually applied in solutions with alcohol, ether, acetone, wood spirit and the like is, in and of itself, a too brittle layer, so that the addition of resins, oils. Camphor and the like. Is required to make this layer pliable. For photographic These common additives make a drawback because the resins or purposes Oils have a decomposing effect on the emulsion layer applied to the skins.
Es fehlte bisher an einem geeigneten chemisch völlig indifferenten Zusatzmittel, welches den Filmhäuten eine genügende Geschmeidigkeit gibt und dennoch vollständig indifferent gegen die Emulsionsschicht ist. Ein solches Mittel bietet sich im Nitroglyzerin. Dasselbe gestattet die Herstellung äußerst schmiegsamer und allen Anforderungen entsprechender Filmhäute.So far there has been no suitable chemically completely indifferent additive which would provide the Gives film skins sufficient suppleness and yet completely indifferent to is the emulsion layer. One such remedy is nitroglycerine. The same is permitted the production of extremely pliable film skins that meet all requirements.
Für die Herstellung von Films ist ein Gehalt der Nitrocellulose an Nitroglyzerin zwischen 5 bis 20 Prozent erforderlich.For the production of films, the nitrocellulose content of nitroglycerin is between 5 to 20 percent required.
