摘　　要：本文报道了硬脂酸镍(NiSt2)对以异位合成AgBr乳剂为光敏元的光敏热显影(PTG)材料感光性能的影响.结果表明AgBr与AgTTA的摩尔比为0.25时,PTG材料感光度最大,并且硬脂酸镍可将感光度提高约1.1倍。本文通过对AgBr乳剂的光吸收和硬脂酸镍的DSC的研究,初步分析了硬脂酸镍对PTG材料感光性能的影响原因.The influence of nickel stearate on the photographic properties of photothermographic （PTG） materials based on AgBr emulsions obtained from an ex-situ preparation was reported. The results showed that the maximal sensitivity of PTG materials could be obtained when the ratio of AgBr to AgTTA was 0. 25, and the sensitivity of PTG materials with nickel stearate was 1.1 times higher than the origin one. The possible reason of the influence of nickel stearate on the photographic properties was studied primarily by UV-Vis of AgBr grains and DSC of nickel stearate.
