Abstract:
A silver halide photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, which has a characteristic curve drawn in orthogonal coordinates of logarithm of light exposure (x-axis) and optical density (y-axis) using equal unit lengths for the both axes, on which gamma is 5.0 or more for the optical density range of 0.3-3.0, and is in the shape of a light-shielded light-sensitive material roll comprising a light-sensitive material roll including the light-sensitive material wound around a roll core, disk-shaped light-shielding members each attached to each of both ends of the roll core and having a radius approximately equal to a radius of the light-sensitive material roll and a light-shielding leader comprising a long length light-shielding sheet having a length longer than a length around the disk-shaped light-shielding member and a width approximately equal to a width of the long length light-sensitive material sheet and heat-shrinkable light-shielding film strips that have a length longer than a length around the disk-shaped light-shielding member, can be torn along the length direction and attached to both sides of the long length light-shielding sheet along side ends so that the strips each could extend from the long length light- shielding sheet in the transverse direction, and wherein the extending portions of the heat-shrinkable light-shielding film strips exceed outer peripheries of the disk-shaped light-shielding members and are fused to outside surfaces of the disk-shaped light-shielding members in a state that the extending portions of the heat-shrinkable light-shielding film strips are thermally shrunk mainly along the length direction, wherein the silver halide photographic light-sensitive material has a film surface pH of 6.0 or less for the emulsion layer side.
