| titleOfInvention | Method for preparing a fogged typed direct positive silver halide emulsion |
| abstract | There is disclosed a method for preparing a direct reversal type silver halide light-sensitive emulsion which is used for a black-and-white light-sensitive material and has the improved photographic performances of a high sensitivity and a high contrast. The method comprises: A method for preparing a fogging type direct positive silver halide emulsion comprising the steps of: (a) forming an emulsion containing silver halide grains; (b) fogging surfaces of the grains with a reducing agent to form a silver nuclei; and then (c) performing at least one of an adjustment of pH of the emulsion to 4.5 or less and an adjustment of pAg of the emulsion to 8.1 or more. |
