ABSTRACT:
A method for processing silver dye-bleach materials, with the process measures silver developing, dye bleaching, silver bleaching and fixing, wherein the silver and dye bleaching can be combined in a single treatment step is provided. For the silver bleaching or the combined dye and silver bleaching an acid formulation is used which has a pH value of at most 2 and contains a strong acid, a water-soluble iodide, optionally a water-soluble organic nitro compound, a non-quaternised quinoxaline or pyrazine, an anti-oxidant and at least one quaternary ammonium salt or a protonated tertiary organic nitrogen base. By this method the processing time can be shortened without impairing the quality of the colored images obtained.
