Description

Photographischer Dreipack für Farbenphotographie Es ist bekannt, nach dem Dreipackprinzip mit einer einzigen Aufnahme in einer mit der gewöhnlichen Objektivanordnung ausgestatteten Kamera Dreiteilfarbennegative gleichzeitig zu erzeugen. Hierfür wird im alIgemeinen -ein Dreipack verwendet, bei dem die dem Objektiv zunächst liegende Platte eine blauempfindliche Emulsionsschicht und auf der Rückseite eine Gelbfilterschicht trägt. Die letztgenannte dient als Filter für die nächste, eine grünempfindliche Emulsionsschicht tragende Platte, die ihrerseits auf der Rückseite eine als Filter für die am weitesten rückwärts gelegene panchromatische Platte bestimmte orangegelb angefärbte Filterschicht besitzt. Man benötigte also zur Zusammenstellung des Dreipacks zwei Spezialplatten, die infolge der auf ihrer Rückseite anzubringenden Filterschichten bei anderen photographischen Verfahren nicht verwendbar sind und daher für den vorliegenden Fall besonders angefertigt werden müssen.Photographic three-pack for color photography It is known after the three-pack principle with a single recording in one with the usual lens arrangement equipped camera to produce three-part color negatives at the same time. For this is In general, a three-pack is used, in which the lens next to it Plate has a blue-sensitive emulsion layer and a yellow filter layer on the back wearing. The latter serves as a filter for the next, a green-sensitive one Emulsion layer carrying plate, which in turn acts as a filter on the back orange-yellow determined for the furthest backward panchromatic plate colored filter layer. So you needed to put together the three-pack two special plates, which as a result of the filter layers to be attached to their back are not useful in other photographic processes and therefore for the present Case need to be customized.

Gegenstand der Erfindung ist ein Dreipack, bei dem alle notwendigen Filterschichten mit dem mittleren Schichtträger vereinigt werden. Der vordere, mit einer blauempfindlichen Emulsionsschicht versehene Schichtträger (Platte oder Film) trägt ebenso wie der rückwärtige, mit panchromatischer Emulsionsschicht ausgestattete Schichtträger (Platte oder Film) keine Filterschichten. Beide werden mit einem mittleren Schichtträger vereinigt, der als vorderste Schicht eine Gelbfilterschicht und unmittelbar hinter dieser eine grünempfindliche Emulsionsschicht trägt, während seine rückwärtige Seite mit einer Rotfilterschicht überzogen ist.The invention is a three-pack, in which all necessary Filter layers are combined with the middle layer support. The front one, with Substrate (plate or film) provided with a blue-sensitive emulsion layer as well as the rear, equipped with a panchromatic emulsion layer Substrate (plate or film) no filter layers. Both come with a mean Layer carrier combined, the foremost layer a yellow filter layer and immediately behind it carries a green-sensitive emulsion layer, while its rear Side is covered with a red filter layer.

Der Vorteil des neuen Filmpacks liegt in erster Linie in der technischen Vereinfachung seiner Zusammenstellung, da für zwei seiner Teile. (vorderer und rückwärtiger Schichtträger) keine Sonderanfertigung mehr notwendig ist.The main advantage of the new film pack is the technical one Simplification of its composition, as for two of its parts. (front and rear Special production is no longer necessary.
