ABSTRACT:
A silver halide emulsion is disclosed which contains silver halide grains formed in the presence of a silver halide solvent. The solvent is a benzimidazole derivative having a hydrogen atom connected to the nitrogen atom at the 1st position thereof. By using this particular solvent a regular silver halide photographic emulsion having high sensitivity causing less fog is obtained. The silver halide solvent is unexpectedly advantageous in that can be almost completely desorbed from the silver halide grains by washing.
