PURPOSE:To improve the stability of a dye image and to prevent stain of the formed dye image by incorporating one kind of compd. among aliphat. isocyanate compds. into a developable image receiving element or photosensitive element. CONSTITUTION:At least one kind of the compd. among the aliphat. isocyanate compds. is incorporated into the developable image receiving element or photosensitive element of a heat developable photosensitive material consisting of the heat developable photosensitive element having the heat developable photosensitive layer contg. a dye donative material on base and the heat developable image receiving element having a lamination relation with the photosensitive element at the time of transferring the dye formed at least on said photosensitive element. The stability of the formed dye image is thereby improved and the generation of stain is decreased; in addition, the preservable property is improved as well. |
