摘　　要：分别研究了Pb2+和Zn2+对以聚乙烯醇(PVA)为粘合剂的亲水型光敏热成像(PTG)材料的感光性能以及老化稳定性能的影响.实验结果表明,涂布液中加入Pb2+或Zn2+后,PTG材料的热显影灰雾和相对感光度均明显降低,并且随着离子加入量的增加,下降程度更加显著.另外,含有Pb2+或Zn2+的PTG材料在经过不同时间的老化后,与未老化PTG材料相比,其热显影灰雾缓慢增加,相对感光度也略有上升.The effect of Pb^2＋ and Zn^2＋ on the photographic properties and storage stability of hydrophilic PTG materials using PVA as binder was respectively investigated. The results showed the thermal development fog and relative .sensitivity of PTG materials were all significantly decreased by adding Pb^2＋ or Zn^2＋ to the coating dispersions, and those of PTG materials debased more quickly with the increase of percentage of Pb^2＋ or Zn^2＋ . In addition, the thermal development fog increased slowly and relative sensitivity increased slightly relative to the primitive PTG materials after the PTG materials including Pb^2＋ or Zn^2＋ aged through different time.
