    摘要: There is disclosed an oxidation-reduction imaging forming composition comprising an aqueous based dispersion of (i) nanoparticulate silver carboxylate particles having on the surface of the particles a surface modifier which is a phosphoric acid ester and (ii) an organic reducing agent. In particular, the surface modifiers can be mixtures of mono- and di-esters of orthophosphoric acid and hydroxyl-terminated, oxyethylated long-chain alcohols or oxyethylated alkyl phenols or derivatives thereof. Also disclosed are various compositions including the dispersions including oxidation-reduction imaging forming compositions, thermographic elements and photothermographic compositions and elements. The preferred carboxylate is a silver salt of a long chain fatty acid such as silver behenate. A media milling method and a controlled precipitation method of making the dispersions are also disclosed

    摘要: Image-forming materials including photographic, thermographic, and thermally-developable imaging materials include one or more transparent electrically conductive, non-charging layers to provide antistatic control on one or both sides of subbed or unsubbed supports. The electrically conductive, non-charging layers comprise colloidal, electrically conductive polymer particles that can be dispersed in a film-forming binder in an amount to provide from about 10 to about 90 volume % of polymer particles. Particularly useful polymer particles include pyrrole-containing, thiophene-containing, and aniline-containing polymers. The particles generally exhibit a packed powder specific resistivity of 105 ohm-cm or less and generally have a mean diameter of 0.5 &mgr;m or less. The electrically conductive, non-charging layers generally exhibit a surface electrical resistivity of less than 1×1012 ohm per square.

    摘要: There is disclosed a nanoparticulate dispersion of a silver carboxylate particles having on the surface of the particles a surface modifier which is a nonionic oligomeric surfactant based on vinyl polymer with an amido function. In particular, the surface modifier is acrylamide, methacrylamide or derivatives thereof. Also disclosed are various compositions including the dispersions including oxidation-reduction imaging forming compositions, thermographic elements and photothermographic compositions and elements. The preferred carboxylate is a silver salt of a long chain fatty acid such as silver behenate.
