ABSTRACT:
A heat-developable photographic material having a light-sensitive silver halide, a reducing agent, a binder and a dye-donating compound on a support, in which at least one light-sensitive silver halide emulsion on the support contains from 1.times.10.sup.-7 to 1.times.10.sup.-3 mol, per mol of silver halide, of iron ions in the silver halide grains. The material shows little sensitivity fluctuation to variations of the temperature of exposure and shows little decrease in sensitivity on exposure with high intensity light for a short period of time, such as laser rays.
