Description

Verfahren zur Herstellung photographischer Farbstoffbilder Die vorliegende Erfindung bezieht sich auf Verfahren zur Herstellung photographischer Farbstoffbilder aus durchgehend angefärbten Silberbildern durch Behandlung mit oxydierenden, in der Schicht keinen freien Sauerstoff abgebenden Bädern oder mit gegenüber dem Farbstoff an sich indifferenten, in Gegenwart des Silberniederschlages farbstoffzerstörend wirkenden Bädern. Die Erfindung besteht in der Anwendung der vorgenannten Bäder bei einer erhöhten Temperatur.Process for preparing dye photographic images The present Invention relates to methods of making dye photographic images from continuously colored silver images by treatment with oxidizing, in the layer does not have free oxygen-releasing baths or with opposite the dye inherently indifferent, destroys the dye in the presence of the silver precipitate acting baths. The invention consists in the use of the aforementioned baths at an elevated temperature.

Es ist in der Photographie bekannt, die Behandlungsbäder, wie z. B. Entwickler, Fixierbad und Tonbäder, bei höherer Temperatur anzuwenden. Es wurde die überraschende Wirkung gefunden, daß die farbstoffzerstörenden Reaktionen bei geringer Erhöhung der Einwirkungstemperatur schon in bedeutend kürzerer Zeit wirken und diese Wirkung unverhältnismäßig größer ist, als es nach Erhöhung der Temperatur zu erwarten wäre.It is known in photography that treatment baths, such as. B. Developer, fixer and clay baths, to be used at higher temperatures. It was found the surprising effect that the dye-destroying reactions at a slight increase in the exposure temperature will have an effect in a significantly shorter time and this effect is disproportionately greater than it would be after an increase in temperature would be expected.

Des weiteren wurde auch gefunden, daß es wirtschaftlich sehr vorteilhaft ist, mit Bädern von erhöhter Temperatur zu arbeiten, weil man nach diesem erfindungsgemäßen Verfahren mit Bädern von viel geringerer Konzentration der wirksamen Substanzen auskommt. Überraschend war hierbei noch, daß die Weißen der nach diesem Verfahren behandelten Bilder viel reiner sind. Es ist außerdem erfindungsgemäß möglich, durch Änderung der Temperatur die Gradation der Bilder zu beeinflussen.Furthermore, it has also been found to be very beneficial economically is to work with baths of elevated temperature, because one according to this invention Procedure with baths of much lower concentration of the active substances gets by. It was still surprising that the whites were using this method treated images are much purer. It is also possible according to the invention through Changing the temperature will affect the gradation of the images.

Als Beispiele seien genannt eine Lösung von o,8 g Calciumhypochlorit, i g Eisessig, ioo g Wasser - zum Gebrauch wird mit gleicher Menge Wasser verdünnt und auf 33° C erwärmt -, oder eine Lösung von 5 g Thiocarbamid, z g Zitronensäure, ioo g Wasser - zum Gebrauch wird mit gleicher Menge Wasser verdünnt und auf 30 bis 32'C erwärmt -.Examples include a solution of 0.8 g calcium hypochlorite, ig glacial acetic acid, 100 g water - for use it is diluted with the same amount of water and heated to 33 ° C - or a solution of 5 g thiocarbamide, zg citric acid, 100 g water - for use it is diluted with the same amount of water and heated to 30 to 32'C -.
