Description

Die Erfindung betrifft ein Verfahren zum Herstellen von Mehrfarbenbildern durch· Umkehrentwicklung. Das dabei verwendete Material lenfhält vorzugsweise drei, und zwar eine für blaues,.eine für grünes und eine für rotes Licht empfindliche TeilscHch'ten, die auf derselben Unterlage vereinigt sind; doch ist die Anwendung des Verfahrens in beiner Weise auf ein solches Material beschränkt.The invention relates to a method for Making multicolor images by · reversal development. The material used for this lenf preferably holds three, one for blue, one for green and one for red light sensitive parts that are united on the same document; but the application of the method is in two ways Way limited to such material.

So kann man z. B. auch ein Material verwenden, das verschiedene sensibilisierte Ha-. logensilberkörner in einer EmulsionsschichtSo you can z. B. also use a material the various sensitized ha-. grains of lue silver in an emulsion layer

Beim Verfahren der Erfindung kann die Wiedergabe von farbigen Objekten oder Vorlagen dadurch in gewünschtem Sinne beeinflußt und verbessert werden, daß man das "bei der Aufnahme oder beim1 Kopieren belichtete Material vor detn Entwickeln äußerst vor-In the method of the invention, the reproduction of colored objects or templates can be influenced in the desired sense, and are improved by the "most upstream in the recording or 1 Copy exposed material before developing DETn

ao sichtig diffus nachbelichtet: Man kann dabei alle latenten Teilfarbenbilder nachbelichten oder diese Belichtung auf bestimmte Teilschichten beschränken. Im letzten Falle wird mit farbigem1 Licht nachbelichtet, das nur auf die gewünschten Schichten wirkt. «5ao visibly diffuse post-exposure: You can post-expose all latent partial color images or limit this exposure to certain sub-layers. In the latter case, 1 colored light is post-exposed, which only affects the desired layers. «5

Die Nachbelichtung' erweist sich in verschiedener Hinsicht als nützlich. Man kann zunächst eine Verstärkung der latenten Bilder allgemein und dadurch eine größere Klarheit und Brillanz der farbigen Umkehrbilder erreichen. Ferner läßt sich durch Nächbelichten einzelner Tieilschichten mit farbigem Licht bzw. durch Farbfilter hindurch der Farbton der Umkehrbilder ändern, was' besonders zur Unterdrückung eines' Farbstichs ausgenutzt werden kann.Post-exposure 'proves useful in a number of ways. One can first of all an intensification of the latent images in general and thereby greater clarity and achieve the brilliance of the colored reversal images. Furthermore, by re-exposure individual layers with colored light or through color filters the color tone change the reversal images, which is used 'especially to suppress a' color cast can be.

Das folgende Beispiel zeigt, wie ein Farbstich eines Dreifarbenbildes beim Kopieren beseitigt werden kann. Angenommen, das Dreifarbenbild zeigt einen Rotstich. Nach dem Kopieren wird in diesem Falle mit blaugrünem Licht- diffus belichtet,' dessen Fartje The following example shows how a color cast of a three-color image can be eliminated when copying. Suppose that Three-color image shows a red cast. In this case, after copying, a blue-green light diffuse is exposed, 'its Fartje
