PROBLEM TO BE SOLVED: To manufacture a dry photosensitive and heat-sensitive material for forming an image of high picture quality by coloring, then exposing and heating and then decoloring. SOLUTION: A recording layer, containing a coloring matter formed by the action of an electron donative colorless dye and an electron acceptive colorless dye or a coloring matter formed by the action of an electron acceptive colorless dye and an electron donative compound, a decoloring agent being brought into contact with the above coloring matter and decoloring matter and an photopolymeric compound having a polymeric vinyl monomer section, is formed at least on one face of a substrate. The recording layer is preferably of an embodiment of containing the above coloring matter and the above polymeric decoloring agent having polymeric vinyl monomer sections, the embodiment of containing the above photopolymeric coloring matter having polymeric vinyl monomer sections and the decoloring agent, the embodiment of containing the coloring matter to be decolored by an external irritation and a photopolymeric compound having the polymeric vinyl monomer sections or other embodiments of similar kinds. |
