PHTHALIMIDE BLOCKED POST-PROCESSING STABILIZERS FOR PHOTOTHERMOGRAPHY

摘要

Photothermographic elements having improved post-processing stability 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 formula (I), wherein A represents any monovalent group for which the corresponding compound AH functions as a post-processing stabilizer.
