ABSTRACT:
This invention provides a process for preparing a bleach accelerator silver salt dispersion by precipitating a salt of a bleach accelerating compound and a silver salt wherein the vAg is maintained at a predetermined level during the precipitation. This invention further provides a photographic element containing a dispersion of grains of a bleach accelerator silver salt wherein the grains are isomorphic or derived from needle or platelet isomorphic crystals.
