Description

Verfahren zur fotografischen Tonaufzeichnung auf einem Zweipack Gegenstand der Erfindung ist ein Verfahren zur fotografischen Tonaufzeichnung bei der Herstellung von Farbenfilmen nach dein: bekannten Zweipackprinzip.Method of photographic sound recording on a two-pack object The invention is a method of photographic sound recording in manufacture of color films according to your: well-known two-pack principle.

Erfindungsgemäß erfolgt die Tonaufzeichnung durch den Schichtträger hindurch auf denn in der Emulsionsschicht nicht gefärbten Vorderfilm, wobei dieser auf seiner lichtempfindlichen Schicht eine als Filter für die zweite lichtempfindliche Schicht dienende Filterschicht trägt, die komplementär zur Farbenempfindlichkeit bzw. Sensibilisierung der ersten Emulsionsschicht angefärbt ist, mit der sie verbunden ist. Diese Filterschicht wirkt infolge ihrer zur Farbenempfindlichkeit -der ersten lichtempfindlichen Schicht komplementären Färbung gleichzeitig derartig auf die erste Schicht zurück, daß sie jede die Schärfe der Tonaufzeichnung vermindernde Belichtung durch reflektiertes Licht verhindert. Beispiel Auf einen kinematografischen Film mit einer mittels Erythrosin in bekannter Weise für den gelbgrünen Teil des Spektrums sensibilisierten feinkörnigen Emulsionsschicht wird auf der Emulsionsschicht eine Rotfilterschicht aus einer alkoholischen Lösung von Aurin aufgetragen. ' Dieser Film wird zur Aufnahme Schicht auf Schicht mit- einem anderen kinematografischen Film vereinigt, der eine für alle Spektralbereiche sensibilisierte panchromatische Emulsionsschicht trägt. Die Tonaufzeichnung erfolgt durch den Schichtträger des erstgenannten Films hindurch.According to the invention, the sound is recorded through the layer support through on the front film not colored in the emulsion layer, this on its photosensitive layer one as a filter for the second photosensitive Layer serving filter layer carries that complementary to color sensitivity or sensitization of the first emulsion layer to which it is associated is colored is. This filter layer acts as a result of its sensitivity to colors - the first light-sensitive layer complementary coloring at the same time such on the first layer that they each degrade the sharpness of the sound recording Prevented exposure to reflected light. Example on a cinematographic Film with a means of erythrosine in a known manner for the yellow-green part of the Spectrum sensitized fine grain emulsion layer is on top of the emulsion layer a red filter layer made from an alcoholic solution of Aurin is applied. ' This Film is used to record layer on layer with another cinematographic Film united, the one sensitized for all spectral ranges panchromatic Emulsion layer carries. The sound is recorded through the substrate of the the former film through.
