HEAT-DEVELOPING PHOTOGRAPHIC MATERIAL

摘要

The present invention relates to a heat-developable light-sensitive material, or a light-sensitive material that produces image by development through dry heat treatment. The present invention provides a heat-developable light-sensitive material that achieves high sensitivity while experiencing a reduced degree of thermal fogging by employing core/shell type silver halide grains that contain 4-40 mol % of silver iodide and which have a lower silver iodide content in the surface layer than in the internal phase.
