Beschreibung
Zusammenfassung:	Photothermographic compositions comprising a photographic silver halide, an organic silver salt, and a reducing agent for the organic silver salt, display improved stabilty in the presence of a compound having a nucleus of the formula: wherein: A represents any monovalent group for which the corresponding compound AH functions as a post-processing stabilizer, L is a -CO2- or a -CH2O- group that is lost during or after the deblocking step, with A bonded to a carbon atom of this group, and n is 0 or 1.
