Ribonucleic acid (RNA) compounds have been found to function as antifoggants and post-processing print stabilizers in photothermographic elements.

Ribonucleic acid (RNA) as an antifoggant and print stabilizer for

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:

Phthalimide blocked post-processing stabilizers for photothermography

The present invention is a heat developed, photothermographic element comprising a support bearing at least one photosensitive, image-forming photothermographic emulsion layer comprising:

Print stabilizers and antifoggants for photothermography

Photothermographic compositions comprising a photographic silver halide, an organic silver salt, and a reducing agent for the organic silver salt, display improved stability in the presence of a compound having a nucleus of the formula:
