Abstract: A photothermographic film and a method for making same is taught. The film includes a support, a photothermographic imaging layer coated on the support, and a complement film generally confining the photothermographic imaging layer between the support and the complement film. The complement film is applied to the photothermographic imaging layer prior to exposure of the photothermographic imaging layer. The complement film retains any volatile materials present in the photothermographic imaging layer generated when thermal energy is applied thereto to develop a latent image exposed on the photothermographic imaging layer.

Abstract: Aqueous-based thermally sensitive emulsions and imaging materials include a mixture of binders in at least one imaging layer. These binder mixtures include from 70 to about 99 weight % of hydrophilic binders such as gelatin and gelatin derivatives, and the remainder of the total binder weight is composed of one or more hydrophobic binders or water-dispersible polymer latexes. These binder mixtures are particularly useful in imaging layers of thermographic and photothermographic materials and provide long term keeping and reduced crystallization of fatty acids.

Abstract: The present disclosure relates to aqueous dispersions of silver (carboxylate-azine toner) particles wherein the azine content of the particles is from about 0.01 to 10% by weight relative to silver carboxylate. The carboxylates are typically silver salts of long chain fatty acids and the azine toners are the compounds that function as development accelerators and toning agents such as phthalazine. These silver (carboxylate-azine) particles can be used to formulate imaging forming compositions that are useful in aqueous thermographic or photothermographic imaging elements.
