光敏热显成像材料显影过程含银中间体的合成与表征

光敏热显成像(photothermographic material, 简称PTG)材料是近十多年来国际感光界关注的热点。采用液相沉淀法合成了PTG材料热显成像过程的含银中间体邻苯二甲酸二银(Ag₂PA)，并进一步使其与酞嗪(PHZ)络合形成了Ag₂PHZ₂PA·H₂O配合物，通过元素分析、电感耦合等离子体原子发射光谱分析(ICP-AES)对Ag₂PA与Ag₂PHZ₂PA·H₂O配合物的元素组成进行了确定，采用X射线粉末衍射分析(XRD)、傅里叶变换红外光谱分析(FTIR)以及热分析(TG与DSC)等方法对Ag₂PA与Ag₂PHZ₂PA·H₂O进行了表征，实现了对PTG材料热显成像过程含银中间体的定性分析。

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.
