Process for preparing silver halide emulsion utilizing a
photographically useful additive capable of being deactivated and a
deactivating agent therefor and silver halide photographic material
prepared by the process
摘要:
A process for preparing a silver halide photographic emulsion to be used for a photographic material is provided. Therein, additives such as dyes, sensitizers, auxiliary agents to be used upon gold sensitization, and so on are utilized within a period from at the silver halide grain forming time to just before the emulsion coating, and oxidizing agents are added at the time when the functions of the additives become substantially needless to result in conversion of the additives to those having no bad influences on photographic characteristics of the emulsion prepared, or to those having such chemical structures as to facilitate their removal with a washing treatment or the like.Silver halide emulsions prepared by the described process are also disclosed.
