Abstract (en)
[origin: WO8906830A1] A photographic material prepared by using a silver halide emulsion containing silver halide grains wherein a halide distribution is microscopically completely uniform and/or which comprise a core part not containing reduced silver formed upon formation of the grains and a shell part different from the core part in a halide composition, and a process for its preparation are disclosed. This material has excellent properties with respect to sensitivity, gradation, graininess, sharpness, resolving power, covering power, preservability, latent image stability and pressure effect.
