Abstract: In a process for the production of photographic images by the silver dye bleach process, a photograph material is used which, on a base, comprises at least one silver halide-free gelatin layer, which contains a diffusion-resistant bleachable image dye, the gelatin/dye ratio being at most 10:1, and a silver halide emulsion layer which is arranged directly on top of the former layer on the side facing the light source and is free of image dye, and the exposed material is processed in a dye and silver bleach bath which contains a combination of oxidizing agents of the formula (1a) with bleach catalysts of the formulae (2a) and (3), or of the oxidizing agent of the formula (1b) with bleach catalysts of the formula (2b).

Abstract: A process for the production of photographic color images by the silver dye bleach process, by exposure, silver development, dye formation, dye bleach, silver bleach and fixing of a photographic material which, in a light-sensitive silver halide emulsion layer or in an adjacent layer, contains, dispersed in oil, an oil-soluble triazene of the formula ##STR1## and an oil-soluble coupling component of the formula ##STR2## in which Ar.sub.1 is aryl or an aromatic heterocyclic radical, R.sub.1 is hydrogen, alkyl, aryl, hydroxyl, --(CH.sub.2 CH.sub.2 O).sub.r --L.sub.1 or --OL.sub.1, in which L.sub.1 is alkyl and r is 1, 2 or 3, or R.sub.1 is ##STR3## in which V is hydrogen or alkyl, and R.sub.2 is alkyl, aryl or --(CH.sub.2 CH.sub.2 O).sub.r --L.sub.1, or R.sub.1 and R.sub.2, conjointly with the nitrogen atom to which they are bonded, form a ring, A.sub.1 and A.sub.2 independently of one another are an amine of the formula --NT.sub.1 T.sub.2, in which T.sub.1 and T.sub.
