中文摘要：

分别研究了原位AgBr和AgI对亲水性PTG材料的感光性能以及热加工后光稳定性的影响。结果表明，AgBr与硬脂酸银（AgSt）的摩尔比为0．01：1时，PTG材料可取得最大感光度，对于AgI可取得相似的结果。未曝光PTG样片经热显影后，在室内光照条件下产生灰雾的程度不同。含有原位AgI的PTG样片的灰雾增长约0．10左右，而含有原位AgBr的PTG样片灰雾增长约0．20左右。

英文摘要：

The effect of in-situ AgBr and materials and the light stability of thermally AgI on the photographic property of hydrophilic PTG processed ones were respectively studied.The results showed that when the molar ratio of AgBr to silver stearate （AgSt）was 0.01：1,the maximal sensitivity of PTG materials could be obtained,as well as to AgI.When unexposed PTG materials with in-situ AgBr and AgI were thermally processed,different fogs of PTG materials were formed under room light illumination.The increment in fogs of PTG materials with in-situ AgI was about 0.10 whereas that of PTG materials with in-situ AgBr was approximate 0.20.
