Description

Verfahren zum Versehen photographischer Rohfilme mit sichtbarer, kopierfähiger Beschriftung Zusatz zum Patent 467780**) **; Früheres Zusatzpatent 468 374 In dem Hauptpatent 467 780 ist ein Verfahren zum Versehen photographischer Rohfihne mit sichtbarer, kopierfähiger Beschriftung beschrieben, welches dadurch gekennzeichnet ist, daß fortlaufende Zahlen oder Zeichen auf die Rückscite des Schichtträgers mit einer Lösung von Farbstoff in schwerflüchtigen Lösungsmitteln aufgedruckt werden.Process for providing photographic raw films with visible, copiable lettering Addition to patent 467780 **) **; Former additional patent 468 374 The main patent 467 780 describes a process for providing photographic raw film with visible, copiable lettering, which is characterized in that consecutive numbers or characters are printed on the back of the substrate with a solution of dye in non-volatile solvents.

Es wurde nun gefunden, daß die in dieser Weise hergestellte Beschriftung unempfindlicher gegen eine spätere Behandlung der Filmrückseite mit Flüssigkeiten, z. B. beim Polieren, gemacht werden kann, wenn man den Aufdruck mit einem Kolloidüberzug versieht. Man verwendet hierzu Kolloide, welche sich nicht in den Flüssigkeiten lösen, die zum Nachbehandeln, insbesondere zum Polieren des Films, Verwendung finden. Diese Kolloide werden in Lösungsmitteln gelöst, welsche den zur Erzeugung des Farbaufdrucks verwendeten Farbstoff nicht lösen. Das Antragen des Kolloidüberzugs kann unmittelbar nach der Erzeugung des Farbaufdrucks stattfinden. Man bedient sichhierzu der bekannten Antragsvorrichtungen.It has now been found that the lettering produced in this way less sensitive to later treatment of the back of the film with liquids, z. B. when polishing, can be done if the print with a colloid coating provides. For this purpose, colloids are used, which are not in the liquids solve, which are used for post-treatment, in particular for polishing the film. These colloids are dissolved in solvents that are used to produce the color print Do not dissolve the dye used. The application of the colloid coating can be immediate take place after the creation of the color print. The known one is used for this Application devices.

Beispiel Als Überzugslösung wird eine einprozentige Lösung von Benzylcelhtlose in einem Gemisch von Aceton und Benzol verwendet.Example A one percent solution of benzyl cellulose is used as a coating solution used in a mixture of acetone and benzene.
