    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.

    摘要： A silver halide photographic light-sensitive material is disclosed. The material is comprised of a support having thereon a silver halide emulsion layer containing light-sensitive silver halide grains, at least 10% (in number) of said halide grains being tabular grains having a diameter/thickness ratio of not less than 5. The tabular grains include an iodine-containing silver halide solid solution in an interior portion thereof which is contained in areas covering, with regard to its major or minor axis direction, 80% by mole of the silver contained in the grain. Further, the tabular grains have an average iodine content in the internal high iodine phase which is five times that of the silver bromide, iodobromide or chloroiodobromide contained in the phase present outside of the internal high iodide phase. In addition, the silver contained in the internal high iodine phase is not more than 50% by mole of the total amount of silver in the tabular grains. The photographic material has the advantages inherent to the use of tabular grains and has improved pressure resistant characteristics.
