Patentiert im Deutschen Reich vom 9. Mai 1937 an Patenterteilung hekanntgemacht am 18. Dezember 1941Patented in the German Reich on May 9, 1937 Patent granted on December 18, 1941

Die Erfindung betrifft ein Verfahreil zur Regelung der Gradation bei der farbigen Entwicklung photographischer Bilder in HaIogensilberschichten. Dieses Verfahren 'erweist S sich als besonders wertvoll bei der Herstellung von Mehrfarbenbildern, die sich aus mehreren auf demselben Schichtträger vereinten Teilfai'benauszügen zusammensetzen und bei' denen die Teilfarbenbilder nacheinander farbig entwickelt werden.The invention relates to a method for regulating the gradation in color development photographic images in shark silver layers. This procedure 'proves S prove to be particularly valuable in the production of multicolor images that consist of assemble several partial extracts combined on the same substrate and in which the partial color images are successively developed in color.

Ein solches Verfahren ist beispielsweise in dem Patent 616 941 beschrieben. Die Bilder können negativ entwickelt werden,· es wird dazu nach der Schwarzweißentwicklung und Fixierung aller Schichten das Negativsilber in lichtempfindliches Silbersalz zurückverwandeTt und dieses jeweils nur meiner Teilschicht wiederbelichtet und farbig entwickelt. Entsprechendes gilt für die farbige Umkehrentwicklung aus dem restlichen Halogensilber, das nach der ersten Schwarzweißentwicklung in den Schichten verbleibt. Die getrennte Belichtung und Farbentwicklüng wird dabei durch Filterfärbungen oder Siensibilisieruingen in dem MehrscMchtenmaterial ermöglicht, welche der Einwirkung der vorangehenden Behandlungsbäder widerstehen. Such a method is described in patent 616,941, for example. The pictures can be developed negatively, · it becomes this after black and white development and fixation of all layers, the negative silver is converted back into photosensitive silver salt and this in each case only re-exposed and colored in my partial layer. The same applies to the color reversal development from the remaining halogen silver, that remains in the layers after the first black and white development. The separate exposure and color development is caused by filter dyeing or sensitization in the multichannel material allows, which withstand the action of the preceding treatment baths.

Beim Verfahren der Erfindung können die verschiedensten Arten von Farbentwicklern verwendet werden. Darunter fallen die farbkuppelnden Entwickler, die neben der eigentlichen Entwicklersubstanz eine Farbkomponente enthalten, ferner die einheitlichen Direktfarbentwickler, bei denen der. Färbstoff aus zwei oder mehreren Molekülen derVarious types of color developers can be used in the method of the invention be used.

For this purpose, other, non-color-developing or coupling-developing developer substances are added to the color developers, whereby the gradation of the color image in question is reduced. The amounts of the substances used depend on their development capacity or on the coupling capacity of the one and on the extent of the desired gradation reduction.
