摘要/Abstract

摘要： 报道了硬脂酸盐(metal stearate简称:MSt₂,M=Ni、Ba、Ca)对以甲基苯并三氮唑银(silver tolyltriazole简称AgTTA)为银源的光敏热显影(PTG)材料感光性能的影响.结果表明,MSt₂的加入可促进PTG材料的显影,其中加入硬脂酸镍(NiSt₂)后在灰雾增加不大的情况下,最大密度和感光度大幅度提高,而加入硬脂酸钡(BaSt₂)和硬脂酸钙(CaSt₂)后在抑制灰雾的同时,最大密度和感光度也有一定程度的增加.本文通过考察体系组成、含量等对pH、[Ag⁺]、感光性能等的影响,初步分析了硬脂酸盐促进显影的原因.

Abstract: The influence of metallic stearates on the photographic properties of photothermographic (PTG) material based on silver tolyltriazole(AgTTA) was reported. The results showed that the stearates can accelerate the development of PTG material. The addition of NiSt₂ greatly increased the maximum density and the sensitivity together with a slight fog increase. However the addition of BaSt₂ and CaSt₂ did not make such great increase in the maximum density and the sensitivity, together with a slight fog decrease. The development processes were discussed by studying the effect of component and content on pH, [Ag⁺] and the photographic properties.

Key words: stearates, silver tolyltriazole, development accelerator, photothermographic material
