Abstract: High-speed aqueous-based black-and-white photothermographic materials are imageable in any suitable fashion using ultraviolet, visible, infrared, or X-radiation. They can have one or more thermally developable imaging layers on either or both sides of the support and can be imaged with or without a phosphor intensifying screen in an imaging assembly. The photothermographic emulsions and materials have a net Dmin less than 0.25, and require less than 1 erg/cm2 to achieve a density of 1.00 above net Dmin. The imaging layers include hydrophilic binders or water-dispersible latex polymer binders and chemically and spectrally sensitized photosensitive silver halide grains.

Abstract: Solid particle dispersions of certain ascorbic acid esters are prepared in the presence of at least 0.5 and less than 50 weight % of a particle growth modifier based on the weight of the ascorbic acid ester. The particle growth modifier is an alkyl carboxylic acid having from 8 to 22 carbon atoms, an alkyl ester of glycerol wherein the alkyl moiety has from 8 to 22 carbon atoms, or a stereoisomer of the ascorbic acid ester. The resulting aqueous solid particle dispersion can be used in various thermally developable materials including thermographic and photothermographic materials.

Abstract: Thermally developable materials such as thermographic and photothermographic materials include a co-precipitate comprising first and second organic silver salts, the first organic silver salt comprising a silver salt of a nitrogen-containing heterocyclic compound containing an imino group, and the second organic silver salt comprising a silver salt of a mercaptotriazole. The first organic silver salt can be used in the imaging process as a source of reducible silver ions, and the second organic silver salt can be a source of a toning agent. The co-precipitate can be prepared using double-jet precipitation techniques to provide an aqueous dispersion that can be used in imaging formulations.
