Abstract
A photothermographic element has on a support, a photosensitive layer containing a non-photosensitive organic silver salt, a reducing agent, and photosensitive silver halide grains. Sharpness is improved when the volume of the photosensitive layer divided by the number of photosensitive silver halide grains in the photosensitive layer is in the range of 0.005-0.1 .mu.m.sup.3.
Claims9
A photothermographic element comprising on a support, a photosensitive layer containing a non-photosensitive organic silver salt, a reducing agent, and photosensitive silver halide grains, wherein the average occupied volume per silver halide grain, defined as the volume of said photosensitive layer divided by the number of silver halide grains in said photosensitive layer, is in the range of 0.005 cubic micron to 0.1 cubic micron.
