摘　　要：本文综述了近年来光敏热成像(PTG)材料在化学增感方面取得的相关新进展.在分析文献结果以及结合作者相关实验数据的基础上提出了进行化学增感的有效方法,即提高卤化银外部潜影的形成效率,或者提高银离子供应源在显影过程中的热迁移能力.文章对PTG材料在化学增感方面的发展提出了一些见解和想法.New advances of chemical sensitization to photothermographic materials in present years were reviewed in this paper. Based on the analysis of references and the author＇s experimental resuits, the viewpoints relating to effective sensitization methods used to raise the sensitivity of PTG materials by raising the outer latent image formation efficiency of silver halide or improving the thermal transiton ability of silver ions donors were brought forward. Finally, some personal proposals about the development of chemical sensitization of PTG materials were introduced as well.
