Description

Verfahren zur Darstellung von photographischen Filmen. Im Patent 322586 ist die Darstellung einer neuen Gruppe von Äthern der Zellulose beschrieben und in diesem Patent besonders hervorgehoben, daß diese bisher unbekannten Körper sich sehr gut zur Darstellung von photographischen Filmen verwenden lassen.Process for the representation of photographic films. In patent 322586 the representation of a new group of ethers of cellulose is described and In this patent particularly emphasized that this hitherto unknown body itself can be used very well for the display of photographic films.

Gegenstand der vorliegenden Erfindung bildet nun die Verwendung der neuen Benzylzelluloseäther für die Darstellung von photographischen Filmen, die sich durch große Klarheit, Geschmeidigkeit und Wasserechtheit auszeichnen. Vor den mit Hilfe von Nitrozellulose hergestellten Filmen, haben sie den Vorteil der Unentflammbarkeit.The present invention now forms the use of new benzyl cellulose ethers for the display of photographic films, the are characterized by great clarity, suppleness and waterfastness. Before Films made with nitrocellulose have the advantage of being non-flammable.

Beispiel: =o Teile des Benzyläthers der Zellulose werden in go Teilen Benzol und =o Teilen Alkohol unter Zusatz von i Teil Triphenylphosphat gelöst. Die so erhaltene viskose Flüssigkeit wird dann auf horizontalliegende geschliffene Glasplatten ausgegossen und das Lösungsmittel verdunsten gelassen. Man erhält so einen Film von großer Klarheit, Elastizität und besonders großer Widerstandsfähigkeit gegen Wasser, Laugen und Säuren.Example: = o parts of the benzyl ether of cellulose are in go parts Benzene and = o parts of alcohol with the addition of 1 part of triphenyl phosphate dissolved. the The viscous liquid obtained in this way is then poured onto horizontally lying ground glass plates poured out and allowed to evaporate the solvent. You get a film like that of great clarity, elasticity and particularly great resistance to Water, alkalis and acids.

Es können andere geeignete Lösungsmittel oder Mischungen derselben zur Anwendung gelangen. Das Triphenylphosphat kann durch Kampfer oder die allgemein als Kampferersatzmittel bekannten Produkte, wie p-Toluolsulfamid, p-Toluolsulfosäuremethylester, Naphthalin, Oxalsäureester, Acetylentetrachlorid, Trichloracetanilid usw. ersetzt werden.Other suitable solvents or mixtures thereof can be used come into use. The triphenyl phosphate can be obtained by camphor or the general products known as camphor substitutes, such as p-toluenesulfamide, p-toluenesulfonic acid methyl ester, Replaced naphthalene, oxalic acid ester, acetylene tetrachloride, trichloroacetanilide, etc. will.

Auch ohne Zusatz von Kampfer oder Kampferersatzmitteln lassen sich aus den Zellulosebenzyläthern brauchbare Filme herstellen.You can also use it without adding camphor or camphor substitutes make usable films from the cellulose benzyl ethers.
