WHEREIN N IS 1 TO 10, R1 represents atoms completing a 5-member heterocyclic nucleus, Z is alkylene, such as alkylene containing 1 to 10 carbon atoms, and (c) a photosensitive component consisting essentially of photosensitive silver halide, in the absence of an image stabilizer or stabilizer precursor, can provide a developed and stabilized image upon imagewise exposure and then overall heating of the element. The photothermographic element can, but need not, contain a binder for the described components. Other addenda employed in photothermographic materials can be employed with the photothermographic element. A photothermographic element comprising a support having thereon (a) a reducing agent, (b) a silver salt of a thione compound, the thione compound being represented by the formula: |
