ABSTRACT:
Novel heat-developable (photothermographic) films incorporate a silver alkyl sulfonate as a physical developer, and an organic base to neutralize acidity from the silver sulfonate. Preferably a heat-developable film is produced by coalescing a coating composition comprising a silver alkyl sulfonate, a silver halide emulsion as photocatalyst, a reducing agent, and an aqueous latex dispersion.
