发明名称 Photographic silver halide and process comprising a development facilitator.
摘要 <p>A color photographic element comprising a support bearing at least one photographic silver halide emulsion layer containing at least one magenta image dye-forming coupler wherein the magenta image dye-forming coupler is at least one pyrazolo [3,2-c]-1,2,4-triazole, pyrazolo[1,5-b]-1,2,4-triazole or anilino-5-pyrazolone; and, the emulsion layer comprises a development facilitating concentration of a development facilitator coupler comprising a coupling-off group (A) that is represented by the formula -S-R&lt;8&gt;-R&lt;9&gt; wherein R&lt;8&gt; is alkylene containing 1 to 8 carbon atoms and R&lt;9&gt; is a water solubilizing group, wherein the concentration of development facilitator coupler enables no bleach accelerator effect upon exposure and processing of the photographic element.</p>
