摘要:
A heat-developable photosensitive material is disclosed having a high image sharpness. The material is comprised of a heat-developable photosensitive layer which includes an organic silver salt, a photocatalyst, and a reducing agent. An antihalation layer is provided on the opposite face of the material with respect to the side intended for imagewise exposure. The antihalation layer contains a photosensitive halogen-containing compound which reduces the pH of the antihalation layer by photolysis and is colored with a dye which causes a change of color when the pH of the antihalation layer is reduced.
