  Verfahren für Farbenphotographie. 



   Das vorliegende Verfahren bezweckt die Herstellung der Teilfarbennegative für photographische und kinematographische Zwecke. Es wird zu diesem Zwecke ein Film mit einer hochempfindlichen Halogensilberemulsion   verrehen, welche   derart dünn gegossen ist, dass möglichste Transparenz erzielt wird. Die Emulsion wird mit einem Farbensensibilisator versehen, z. B. für blau, welcher die Emulsion derart färbt, dass sie gleichzeitig als Farbenfilter für ein zweites Teilfarbenbild, z. B. gelb dienen kann. Der zur Aufnahme dieses zweiten Teilfarbenbildes bestimmte Film wird hinter dem ersten im Kontakt mit diesem in der Kamera exponiert.

   Zur Herstellung des dritten Teilfarbenbildes werden beide der vorangeführten Films sehr transparent emulsioniert und es wird der für das dritte Teilfarbenbild bestimmte Film im Kontakt mit den beiden ersten hinter diesen exponiert, jedoch wird vor diesem Film noch ein entsprechend gefärbtes Farbfilter (Gelatinefolie) eingeschaltet, während der Film selbst für die betreffende Farbe sensibilisiert ist.

  Procedure for color photography.



   The present process aims at the production of the partial color negatives for photographic and cinematographic purposes. For this purpose, a film with a highly sensitive halogen silver emulsion is twisted, which is cast so thin that the greatest possible transparency is achieved. The emulsion is provided with a color sensitizer, e.g. B. for blue, which colors the emulsion in such a way that it also acts as a color filter for a second partial color image, e.g. B. can serve yellow. The film intended for recording this second partial color image is exposed behind the first in contact with it in the camera.

   To produce the third partial color image, both of the previous films are emulsified very transparently and the film intended for the third partial color image is exposed behind them in contact with the first two, but a correspondingly colored color filter (gelatin film) is switched on in front of this film, during the Film itself is sensitized to the color in question.

PATENT-ANSPRUCH : Verfahren zur Herstellung von Teilfarbennegativen für Dreifarbenphotographie, dadurch gekennzeichnet, dass eine hochempfindliche Halogensilberemulsion von grosser Transparenz zur Anwendung kommt, welche durch einen Farbensensibilisator derart gefärbt ist, dass sie gleichzeitig als Farbfilter für ein anderes Teilfarbenbild verwendbar ist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of partial color negatives for three-color photography, characterized in that a highly sensitive halogen silver emulsion of great transparency is used which is colored by a color sensitizer in such a way that it can be used at the same time as a color filter for another partial color image. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
