    摘要： A silver halide photographic material is disclosed which comprises at least one silver halide emulsion layer on a support, wherein light-sensitive silver halide grains in the silver halide emulsion layer or layers are obtained by charging previously prepared silver halide particles having a fine size into a reaction vessel which allows nucleation and/or crystallization of the light-sensitive silver halide grains so that nucleation and/or crystallization are effected in the reaction vessel, and the light-sensitive silver halide grains are subjected to chemical ripening in the presence of a silver halide solvent. A process for the preparation of the silver halide photographic material is also disclosed.
