【発明の名称】カルボン酸銀ナノ粒子用のリン酸エステル表面改質剤
Document Type and Number:
Japanese Patent JP2003522975
Kind Code:
A
Abstract:
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
