  • Patent number: 5523198
    Abstract: A light-sensitive silver halide photographic material is disclosed. The light-sensitive material comprises transparent support having on each side, side-A and side-B, thereof a silver halide emulsion layer and has a specified balance in speeds of the emulsion layers each provided on side-A and side-B. A specimen obtained by exposing said light-sensitive material from its one side, side-A, followed by processing has a density higher than fog density of side-B by 0.10 or more on side-B of said light-sensitive material when the amount of exposure gives a density higher than fog density of side-A by 0.2; and a density higher than fog density of side-B by 0.70 or less on side-B of said light-sensitive material when the amount of exposure gives a density higher than fog density of side-A by 1.60. The light-sensitive material suited as a film for X-ray photography and gives an image having excellent sharpness and graininess.
