摘要： A silver halide emulsion is disclosed which contains silver halide grains formed in the presence of a silver halide solvent. The solvent is a benzimidazole derivative having a hydrogen atom connected to the nitrogen atom at the 1st position thereof. By using this particular solvent a regular silver halide photographic emulsion having high sensitivity causing less fog is obtained. The silver halide solvent is unexpectedly advantageous in that can be almost completely desorbed from the silver halide grains by washing.

摘要： A silver halide photographic emulsion is described, which has halogen composition comprises at least 60 mole % of silver chloride, 40 mole % or less of silver bromide, and 5 mole % or less of silver bromide. Grain formation is performed in the presence of a silver halide solvent selected from the group consisting of tetrasubstituted thioureas and organic thioethers, and from 10.sup.-8 to 10.sup.-5 mole of a water-soluble iridium compound per mole of silver halide. This photographic emulsion exhibits high sensitivity and provides high contrast even by flash exposure. Thus, it is useful for the production of light-sensitive materials to be used in the production of printing plates in accordance with photographic engraving.
