Color photographic images are produced by decomposing hydrogen peroxide on nuclei present in imagewise distribution and bleaching out a dye by the hydrogen peroxide on those parts of the image where no such nuclei are present.

Process for the production of color photographic images and photographic

New silver halide emulsions are prepared at least partly by converting a silver phosphate with a water soluble halide.

Silver halide emulsion with an average grain size of at most 0.6 .mu.m containing Co-, Ce- or Cu-salts are suitable for the production of vesicular images.

Silver halide emulsion, a photographic material and a process for the

Silver halide emulsions, which have been precipitated in the presence of polymers having recurring units with a 8-hydroxy quinoline structure are suitable for the preparation of vesicular images.

Silver salt emulsion, photographic material and process for the

A photographic material for the production of an image in a dry process by forming a vesicle image upon the decomposition of a peroxide compound at image nuclei of silver by providing a layer containing a silver salt which forms upon exposure to light, in imagewise distribution, image nuclei. The silver salt has a grain size of less than 0.3 .mu.m and is present in the layer in an amount of from 1-500 mg/m.sup.2.
