    摘要: Photothermographic elements having improved post-processing stabilty are described. These elements comprise a support bearing at least one photosensitive, image-forming photothermographic-emulsion layer comprising:(a) a photosensitive silver halide;(b) a non-photosensitive, reducible silver source;(c) a reducing agent for said non-photosensitive, reducible silver source,(d) a binder; and(e) a compound capable of releasing a post-processing stabilizer having a nucleus of the formula: ##STR1## wherein: A represents any monovalent group for which the corresponding compound AH functions as a post-processing stabilizer.

    摘要: The present invention is a heat developed, photothermographic element comprising a support bearing at least one photosensitive, image-forming photothermographic emulsion layer comprising:(a) a photosensitive silver halide;(b) a non-photosensitive, reducible silver source;(c) a reducing agent for silver ions;(d) a binder; and(e) a substituted hydroxyphenyl compound which provides antifoggant and print stabilizing properties to the photothermographic element. The substituted hydroxyphenyl compound may be of the formula: ##STR1## wherein: R represents hydrogen, benzoyl, a five or six membered heterocyclic ring system, or a fused ring system; or of the formula ##STR2## wherein: R.sup.1 represents a disubstituted or a trisubstituted s-triazine group, a disubstituted benz-bis-triazole group, a disubstituted benz-bis-thiazole group, a disubstituted benz-bis-oxazole group, and a disubstituted benz-bis-imidazole group.
