中文摘要：

本文对调色剂酞嗪（PHZ）在苯并三氮唑银（AgBTA）光敏热显影体系中的作用机理进行了初步研究．通过SEM，IR，XRD分析结果表明，PHZ与AgB—TA生成银复合物从而发挥显影促进作用．该复合物可以改变AgBTA颗粒的形状．生成的银复合物具有与AgBTA相同的晶体结构．

英文摘要：

The mechanism of phthalazine （PHZ） on photothermographic materials based on silver benzotriazole had been studied. The results from SEM （scanning electronic microscope）, IR and XRD indicated that a silver complex, which was supposed to be easy to transmit silver ions to devel- opment center to promote development, have been formed by introducing PHZ into the silver benzo- triazole materials. The sharp of silver benzotriazole grains were changed by the silver complexes which were the same crystal structures as silver benzotriazole.
