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.
