Description

Lichtempfindliche Filme, die in der Kamera magnetisch plangehalten werden Das Prinzip der magnetischen Planhaltung photographischer und ähnlicher lichtempfindlicher Filme in der Kamera läßt sich auch dadurch verwirklichen, daß die Schichtträger mit auf magnetische Kraftlinien ansprechenden oder mit permanentmagnetischen Stoffen versehen, sind. Solange Stoffe dieser Eigenschaften nicht transparent sind, müssen diese als Rückschicht auf die Schichtträger gebracht werden.Photosensitive films that are magnetically flat in the camera The principle of the magnetic planarity of photographic and similar photosensitive Films in the camera can also be realized in that the layer supports with substances that respond to magnetic lines of force or with substances that are permanently magnetic provided, are. As long as substances with these properties are not transparent, must these are applied to the substrate as a backing layer.

Die Erfindung betrifft ein Verfahren, bei dem die komplizierten und äußerst empfindlichen Entwicklungsvorgänge in der Schwarzweiß-, der Farben-, Röntgenphotographie usw. nicht durch eingebrachte, leicht oxydierende Fremdstoffe einer magnetischen Rückschicht unkontrollierbar beeinflußt werden.The invention relates to a method in which the complicated and extremely sensitive development processes in black and white, color and X-ray photography etc. not due to the slightly oxidising foreign matter of a magnetic The back layer can be influenced in an uncontrollable manner.

Die flexiblen lichtempfindlichen Schichtträger werden erfindungsgemäß mit einer abziehbaren Folie versehen, die auf magnetische Kraftlinien anspricht oder die magnetische Eigenschaften besitzt. Diese Folie wird dann vor dem Entwicklungsprozeß von der Rückseite des Schichtträgers abgezogen und hinterläßt mit Sicherheit keinerlei Rückstände, die in jedem Entwickler unkontrollierbare Reaktionen auslösen können. Die abziehbare magnetische Folie an Trägern lichtempfindlicher Schichten bietet weiterhin den großen Vorteil, jedes Filmmaterial der laufenden Produktion unter Beibehaltung der erprobten Entwickler zu verwenden. Die von den bekanntesten Filmherstellern aufgezeigten Schwierigkeiten einer direkten Aufbringung magnetischer Rückschichten sind durch die abziehbaren magnetischen Folien restlos beseitigt.The flexible photosensitive supports are according to the invention provided with a peelable film that responds to magnetic lines of force or which has magnetic properties. This slide is then used before the development process peeled from the back of the support and certainly does not leave any Residues that can trigger uncontrollable reactions in any developer. The removable magnetic film on supports of light-sensitive layers offers Farther the great advantage of maintaining any footage while production is in progress the proven developer to use. The ones from the most famous film makers identified difficulties of direct application of magnetic backing layers are completely eliminated by the removable magnetic foils.

Zur Erreichung der magnetischen Planhaltung lichtempfindlicher Schichtträger ist es gleichgültig, aus welchem Material die Folien bestehen und ob die Stoffe mit magnetischen Eigenschaften in die Folien eingebettet oder auf diese aufgebracht werden. Bei Rollfilmen kann die abziehbare magne-To achieve the magnetic flatness of light-sensitive substrates It doesn't matter what material the foils are made of or whether the fabrics are used with magnetic properties embedded in the foils or applied to them will. In the case of roll films, the removable magnetic
