ABSTRACT:
A heat-developable photosensitive material including a photosensitive layer formed on a support, the photosensitive layer at least containing an organic silver salt, a reducing agent, either a photosensitive silver halide or a photosensitive silver halide forming agent, and a sensitizing dye of the following general formula (I): ##STR1## where r is hydrogen, halogen, substituted or unsubstituted alkyl, substituted or unsubstituted alkoxyl, substituted or unsubstituted aryl or substituted amino; r.sup.1 and r.sup.2 are each substituted or unsubstituted aryl or r.sup.1 and r.sup.2 are bonded to each other to form a condensed ring; r.sup.3, r.sup.4 and r.sup.5 are each hydrogen, substituted or unsubstituted alkyl, alkenyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; X.sup.1 is oxygen, sulfur, carbon, nitrogen or selenium, wherein when X.sup.1 is carbon or nitrogen, then X.sup.1 is bonded to hydrogen, substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted aralkyl; X.sup.2 is oxygen or sulfur; X.sup.3 is oxygen or sulfur; and n is 2. A polymerizable polymer precursor and a light polymerization initiator may also be employed in the material.
