PURPOSE:To obtain an image sufficiently high in the max. density without increasing fog by forming an interlayer contg. particles kept in a solid state at the temp. of heat development between 2 photosensitive layers different in color sensitivity formed on a support. CONSTITUTION:The heat developable color photosensitive layer has at least 2 photosensitive layers different in color sensitivity, preferably, 3 photosensitive layers different in color sensitivity from one another, and interlayers contg. particles, such as TiO2 or ZnO2, dispersed in a binder, such as gelatin or cellulose derivs, kept in a solid state at the time of heat development between these photosensitive layers. The use of such interlayers permits transferability of a dye to be improved and an image sufficiently high in the max. density to be obtained without raising the min. density (fog).
