| 摘 要： | CBr4/无色结晶紫(LCV)自由基光敏材料因具有高的光敏性及光显影效应受到重视。但是这种光敏材料贮存稳定性差,室温下放置几天,灰雾密度就超过0.2,使应用受到限制。曾有人采用添加稳定剂,如用Ⅴ族元素的三芳基化合物,酚类等以提高贮存稳定性。但关于稳定性机理的研究尚未见报道,本文介绍初步考察结果。

| Abstract: | CBr4-LCV (Leuco Crystal Violet) free radical film, a representative free radical photographic material,is unstable in storage. In this paper the reason of the unstability of CBr4-LCV system and the effect of the stabilizer s-41 were studied by ESR measurement. The result showed that the hot-induced free radical probably plays an important role in fog production during the storage. |
