摘要:
A silver halide photographic emulsion is disclosed, containing tabular silver halide grains each comprising plural silver halide phases different in a silver iodide content from each other, in which a highest silver iodide containing phase has a silver iodide content of not less than 5 mol % and less than 15 mol %, and a lower silver iodide containing phase is present outside and contiguous to the highest silver iodide containing phase; the tabular grains having 5 or more dislocation lines per grain and accounting for not less than 30% by number of total silver halide grains, the tabular grains further having a hole trap zone within the grain.
