PURPOSE: To improve developability and transferability of dyes without generating fogging and deteriorating a raw preversable property by providing at least one layer of heat-meltable agent layer and shielding layer to transiently shield the effect of the heat-meltable agent in the heat-meltable agent layer on a heat developable photosensitive layer.
CONSTITUTION: At least one layer of the heat-meltable agent layer and the shielding layer to transiently shield the effect of the heat-meltable agent in the heat-meltable agent layer on the heat developable photosensitive layer are provided to the material. All of known heat-meltable agents are usable for the heat-meltable agent; above all, amides, ureas, sulfonamides, polyhydric alcohols, and imides are useful. The form of the shielding layer is arbitrary if said layer has the function to transiently shield the effect of the heat-meltable agent diffused from the heat-meltable agent layer at the time of heat development on the heat developable photosensitive layer; more specifically, said layer is exemplified by a layer contg. a high polymer material as a binder.
