[Synthesis and characterization of silver-intermediates in the development process of photothermographic material].

Photothermographic material (PTG) is one of the frontier subjects in the field of photographic science during the last decade. In the present paper, the silver-intermediate in development process of PTG material-disilver phthalate (Ag2PA) was prepared by the liquid deposition method, and Ag2PHZ2PA x H2O complex was synthesized successfully by liquid dispersion means using Ag2PA and phthalazine (PHZ) as the reactants. The composition of Ag2PA and Ag2PHZ2PA x H2O was determined by ICP-AES and elemental analysis, and the two silver-intermediates were characterized with XRD, FTIR, TG and DSC. As a result, the silver-intermediates in the development process of PTG material, Ag2PA and Ag2PHZ2PA x H2O, were qualitatively analyzed respectively.
