| 摘 要： | 本文考察了不同制备方法、不同种类的光敏剂对以苯并三氮唑银为银源的光敏热成像材料感光性能的影响。结果显示原位法中以AgI和AgBrI为光敏剂的PTG材料具有较高的感光度，分别为以AgBr为光敏剂的参比样片感光度的16倍和2.4倍；异位法制备的PTG材料中，以AgBrI乳剂为光敏剂的感光度比以AgBr为光敏剂的感光度高，是其3倍；此外，同是以AgBr为光敏剂、用异位法制备的PTG材料的感光度比原位法制备的PTG材料感光度高。文中初步分析讨论了出现以上实验结果的原因。

| Abstract: | The effect of different kinds of photosensitizers on the photographic performances of photothermographic materials based on silver benzotriazole was studied. It is found that both PTG materials with AgBrI and AgI as photosensitizers have a higher sensitivity than the PTG material with AgBr photosensitizer in the in-situ systems, the sensitivity is 16 times and 2.4 times as high as the control one. In the ex-situ PTG materials, the sensitivity of the PTG materials with AgBrI emulsion as photosensitizer is 3 times as high as the PTG materials with AgBr emulsion as photosensitizer. Besides, between of the in-situ PTG materials and ex-situ PTG materials with the same AgBr emulsion as photosensitizer, the latter has a higher sensitivity than the former. And the relevant factors were primarily investigated. |
