ABSTRACT:
Certain mercapto heterocyclic compounds in certain photothermographic and thermographic elements and compositions containing silver salts of certain heterocyclic thione compounds and an organic reducing agent for the silver salts provide improved developed image tone. In the photothermographic element comprising photographic silver halide in association with the silver salt of heterocyclic thione, a developed and stabilized image, in the absence of a separate stabilizer or stabilizer precursor, with improved tone, is provided by heating the element. The photothermographic element and composition can contain a binder.
