| 摘 要： | 研究了硬脂酸钡(简称BaSt2)对光敏热成像材料(PTG材料)感光性能的影响,结果表明,AgBr/AgTTA摩尔比为1∶4时,PTG材料感光度最大,加入BaSt2后可将感光度提高4倍左右,而灰雾增加很小。本文通过对AgBr乳剂的光吸收和BaSt2的DSC研究,初步分析了BaSt2影响PTG材料感光性能的可能原因。

| Abstract: | The influence of barium stearate on the photographic properties of photothermographic(PTG) materials was reported.The results showed that the maximal sensitivity of PTG materials ean be obtained when the AgBr/AgTTA molar ratio is 1∶4,and the sensitivity of PTG materials after added barium stearate is increased by four times,and meanwhile fog increase is very small.The possible reasons of the influence of barium stearate on the photographic properties were studied primarily by UV-vis of AgBr grains and DSC of barium stearate. |
