Abstract (en)
[origin: EP0577192A1] A color photographic element comprises a support bearing at least one photographic silver halide emulsion layer, an image dye-forming coupler, and a combination of a development inhibitor releasing coupler and a wash-out coupler,the washout coupler (A) (i) capable of forming a compound that is washed out of the photographic element upon processing and (ii) capable of releasing a bleach accelerator group, and (iii) is represented by the formula: (SOL)x-COUP-(R<1>)y-BLEACH The development inhibitor releasing coupler is selected from a timed and non-timed development inhibitor releasing coupler.
