SILVER HALIDE PHOTOGRAPHIC EMULSION AND PROCESS FOR ITS PREPARATION.

摘要

A silver halide emulsion for photographic use and a process for its preparation. A monodisperse silver halide emulsion containing silver halide grains substantially comprising silver bromoiodide grains of octahedral or tetradecahedral crystals mainly comprising (111) faces with the vertexes round in a definite curvature undergoes less fogging and is highly sensitive. This emulsion is obtained by treating a monodisperse silver halide emulsion containing octahedral or tetradecahedral crystals with a solvent for silver halide.
