<p>PROCESS FOR THE PRODUCTION OF MASKED POSITIVE COLOUR IMAGES BY THE SILVER DYE BLEACH PROCESS The present invention relates to a process for the production of masked subtractive positive colour images in accordance with the silver dye bleach process. In the material to be processed (a) a silver halide emulsion layer consisting at least partially of silver iodide is allocated to the dyestuff, of which the undesired parasitic colour density is to be compensated, (b) in a further layer, at least one second dyestuff, of which the main colour density corresponds to a parasitic colour density, requiring compensation, of the first dyestuff, and a silver halide emulsion free from iodide ions, are present, (c) a further layer, which is adjacent to that containing the second dyestuff, contains colloidal nuclei which are capable of depositing metallic silver from soluble silver complexes, (d) a separating layer is present between the layer containing the nuclei and the dyestuff layer, of which the parasitic colour density is to be compensated. The silver developer bath, with which the material is treated contains a ligand, which is able to produce water-soluble silver complexes which are capable of diffusion. -1-A</p> |
