摘要/Abstract

摘要： 报道了不同反应模式下四甲基硫脲(TMT)对PTG材料感光性能的影响,结果表明在[(TMT+AgBr)+AgTTA]模式和[(AgTTA+AgBr)+TMT]模式下,感光度增加幅度较小,灰雾增加较大,而在[(TMT+ AgTTA)+ AgBr]模式下感光度提高最大,而且灰雾增加较小.本文通过分析TMT对光敏元和银盐的作用初步得出TMT对PTG材料感光性能影响的可能原因.

Abstract: The influence of tetramethylthioharnstoff (TMT) on the photographic properties of photothermographic (PTG) materials was reported respectively in three models, where the TMT, AgBr and the silver tolyltriazole (AgTTA) were mixed in different orders. Compared with the model [(TMT+AgBr)+AgTTA] and [(AgTTA+AgBr)+TMT], the sensitivity of PTG materials was found to have the largest improvement, and the fog increased a little in the model [(TMT+ AgTTA)+ AgBr]. The possible reason of the influence of TMT on the photographic properties was achieved by analyzing the effect of the TMT on the photosensitive element and the silver salt.

Key words: tetramethylthioharnstoff, silver bromide, nickel stearate, silver tolyltriazole, photothermographic material
