ABSTRACT:
Thermally developable photothermographic materials comprise a backside layer that includes a backside stabilizer to reduce fog formation in high humidity conditions, thereby providing improved shelf stability. Useful backside stabilizers are nitrogen-containing aromatic heterocyclic compounds. These backside stabilizers can be provided particularly in non-photosensitive compositions that include an antihalation composition.
