Description
Film zur episkopischen Projektion. Die episkopische Projektion photographischer und insbesondere kinematographischer Bilder gewinnt in neuerer Zeit immer mehr an Interesse. Dazu benutzte Bildbänder besaßen bisher als Träger der photographischen Schicht entweder Betall-, insbesondere Aluminiumfolien, oder Papierstreifen, die mit einem Silberspiegel versehen waren. Beide Ausführungsformen zeigen erhebliche .Nachteile. Die Metallfolie entbehrt der für die ruckweise Vorführung für kinematographische Zwecke notwendigen Schmiegsamkeit und zeigt kein sehr großes Reflexionsvermögen für das Licht; selbst bei der Anwendung Hochglanz gestattender Metalle geht dieser durch die Einwirkung der Chemikalien (Entwickler usw.) verloren. Papierunterlage mit Spiegelbelag ist schon wegen der geringen Wasserfestigkeit des Papieren nicht brauchbar, aber auch im trockenen "Zustande genügt sie nicht den mechanischen Anforderungen, die der kinematographische Vorführungsapparat mit seiner starken Beanspruchung stellt. Weiterhin ist der Spiegel ebenfalls der Einwirkung des Entwicklers ausgesetzt, läuft dabei an und absorbiert dann den größten Teil des darauffallenden Lichtes.Film on the episcopal projection. The episcopal projection photographic and cinematographic images in particular are gaining more and more importance in recent times Interest. Image tapes used for this purpose have hitherto been used as a carrier for the photographic one Layer either betall, especially aluminum foils, or paper strips that were provided with a silver mirror. Both embodiments show significant .Disadvantage. The metal foil lacks that for the jerky demonstration for cinematographic Purposes necessary flexibility and does not show a very high reflectivity for the light; this is even possible when using metals that allow a high gloss lost due to exposure to chemicals (developer, etc.). Paper pad with a mirror coating is not possible because of the poor water resistance of the paper usable, but even in the dry "state it does not meet the mechanical requirements, which the cinematographic demonstration apparatus with its heavy use makes. Furthermore, the mirror is also exposed to the action of the developer and runs at the same time and then absorbs most of the light falling on it.
Diese 1Tachteile werden sämtlich vermieden, und es wird eine außerordentlich günstige Unterlage dadurch geschaffen, daß man einen im wesentlichen aus Zelluloseäthern oder -estern bestehenden Träger für die photographische Schicht wählt, in welchem feinstes Metallpulver (sogenannte Bronzefarbe) eingebettet ist, was man beispielsweise dadurch erzielt, daß man in einer Auflösung von Nitrozellulose bzw. Azetylzellulose und den üblichen Beimischungen Bronzepulver aufschlemmt und diese Lösung auf einer ebenen Fläche zu einem Film ausgießt. Die so erhaltenen Folien zeigen durch das Vorhandensein der in einer Lackschicht von höchstem Glanz und glasglatter Oberfläche eingebetteten 11etallflitter ein überaus hohes Reflexionsvermögen und besitzen weiterhin dieselbe Geschmeidigkeit wie die sonst für gewöhnliche kinematographische Zwecke verwendeten Filme. Weiterhin schützt die Einlagerung des Metalles in die für wäßrige Flüssigkeiten undurchlässigen plastischen Massen das 1Ietall vor Oxydation, Anlaufen -usw. infolge Einwirkung von Entwickler, Luft usw. Das Reflexionsvermögen desFilms ist schon völlig hinreichend, wenn der Gehalt an Metallpulver so gering ist, daß der Film mit bloßem Auge noch durchsichtig erscheint; es kamt weiterhin unter Ersparnis von Bronzepulver erhöht werden, wenn man die der photographischen Schicht gegenüberliegende Seite dunkel färbt oder sie undurchsichtig macht oder aber den Film in dieser Weise auf eine undurchsichtige Unterlage aufzAf.' Selbstverständlich kann der Filrn. auch,->v@un auf hohe Geschmeidigkeit kein Wert gelegt wird, auf ein Metallband aufgezogen werden oder auch der Film in oben beschriebener Weise sogleich auf einem Bande aus Metall oder anderem Material erzeugt werden.All of these drawbacks are avoided, and it becomes a tremendous one cheap pad created by one essentially made of cellulose ethers or -ester existing support for the photographic layer in which finest metal powder (so-called bronze color) is embedded, which is one example achieved in that one in a dissolution of nitrocellulose or acetyl cellulose and the usual admixtures of bronze powder and this solution on one pours into a film on a flat surface. The films obtained in this way show by the Presence of the lacquer layer of the highest gloss and a smooth glass surface embedded metal tinsel and still have an extremely high reflectivity same smoothness as that used for ordinary cinematographic purposes used films. Furthermore, the storage of the metal in the for aqueous Liquids impermeable plastic masses protect the metal from oxidation and tarnishing -etc. due to exposure to developer, air, etc. The reflectivity of the film is completely sufficient if the content of metal powder is so low that the film still appears transparent to the naked eye; it continued to come under savings of bronze powder when the opposite of the photographic layer Color the page dark or make it opaque or the Movie in this way on an opaque surface. ' Of course you can the filrn. also, -> v @ un no value is placed on high flexibility, on a metal band be drawn up or the film in the manner described above immediately on a Bands made of metal or other material are created.
