Patent ID: 7118851

Claim:
A heat-developable light-sensitive material comprising a support having on the same surface thereof a light-sensitive silver halide emulsion, a light-insensitive organic silver salt, a heat developer and a binder, wherein said light-sensitive silver halide emulsion comprises at least a dispersion medium, water and silver halide grains, wherein silver halide grains occupying from 40 to 100% of the total projected area of said silver halide grains have an AgI content of 85 to 100 mol %, the outer surface of said silver halide grains has a face having at least one shape selected from the group consisting of a hexagon, a parallelogram and a trapezoid, said silver halide grains having a single kind of outer grain shape, except for size, having an equivalent-circle projected diameter of from 0.002 to 20 μm and having a coefficient of variation in the diameter distribution of the grains of from 0.01 to 0.3.
