ABSTRACT:
A heat developable light-sensitive material is disclosed which is provided with a protective layer comprising, as a major constituent, a nonionic, hydrophilic polymer. On heat developing the light-sensitive material, a mobile dye image is formed which can be transferred to a dye fixing material superposed on the light-sensitive material. After the transfer of the dye image, the light-sensitive material can be readily separated from the dye fixing material due to the presence of the protective layer, and thus a sharp image can be formed in the dye fixing material.
