Abstract:
A photothermographic element comprising on a support a non-photosensitive organic silver salt, a photosensitive silver halide which has been formed independent of the non-photosensitive organic silver salt, and a binder,said photothermographlic element further comprising an image forming layer which contains the photosensitive silver halide, a binder, a synthetic latex of a polymer having a glass transition temperature of -30.degree. C. to 40.degree. C. accounting for at least 50% by weight of the binder, and at least one compound of the following formula (I): ##STR206## wherein X is --N.dbd., --N(R)--, --O--, or --S--, wherein R is hydrogen, hydroxyl, aliphatic hydrocarbon, aryl or heterocyclic group,Z is a single bond or a group of non-metallic atoms necessary to form a 5- to 7-membered ring with X, andQ.sub.1 and Q.sub.2 each are a group of non-metallic atoms necessary to form an aromatic hydrocarbon ring or aromatic heterocyclic ring fused to the ring completed by Z.
