Silver halide emulsion, process for preparing the same, and silver halide photographic materials containing the same |
摘要 |
A process for producing a silver halide emulsion comprising tabular silver halide grains containing not less than 10 mol% of silver chloride and having {100} faces as major faces and an average aspect ratio of 2 or higher, which tabular silver halide grains are prepared by comprising rising temperature of a grain formation system after completion of (a) nucleation step and taking (c) grain growth step, which process comprises adding silver ions in an amount corresponding to at least 1 mol% of the total silver content to the silver halide emulsion at a stage after introduction of a halogen gap in the nucleation step (a) and before the grain growth step (c).
