Abstract (en)
[origin: EP0616255A1] A process is disclosed of producing a dye image in an imagewise exposed color photographic element by developing a silver halide emulsion to produce silver imagewise and employing the developed silver to catalyze the reaction of an oxidizing agent and a reducing agent that are inert to oxidation-reduction interaction in the absence of developed silver, and reacting oxidized reducing agent with a dye image providing compound to form the dye image. In the color photographic element total silver is limited and the emulsion contains a high chloride ä100ü tabular grain population.
