摘要： A process for producing a tabular silver halide emulsion by using a sulfur-containing silver halide solvent that promotes growth of silver halide grains, and a light-sensitive material containing the emulsion are disclosed. The grain growth effect of the silver halide solvent is reduced or eliminated by using an oxidizing agent thereby excluding the adverse effect of the silver halide solvent upon chemical ripening.

摘要： A silver halide photographic light-sensitve material is disclosed. The material is comprised of a transparent support having provided on one side of the support at least two silver halide emulsion layers and a surface-protecting layer. One of the two silver halide emulsion layers is a tabular silver halide emulsion layer containing tabular silver halide grains having a diameter at least five times the thickness of the grains. The other silver halide emulsion layer is a non-tabular silver halide emulsion layer containing non-tabular silver halide grains. The tabular silver halide emulsion layer is positioned closer to the support than the non-tabular silver halide emulsion layer, and the non-tabular silver halide emuslion layer is positioned closer to the support than the surface-protecting layer. The material may include two similar silver halide emulsion layers and a surface-protecting layer on the opposite side of the support. The material provides images with improved sharpness without a decrease in sensitivity while effectively utilizing the amount of silver.
