摘要: 本文以水性聚乙烯醇(PVA)为粘合剂,原位法合成的AgBr作为光敏元,考察了组分四氯邻苯二甲酸、酞嗪以及三溴甲基砜类防灰雾剂在体系不同pH值时对PTG材料感光性能的影响.实验结果表明:防灰雾剂可以明显地降低灰雾和减小最大密度;体系pH在7.0-7.5之间时,感光度最大,而灰雾随着体系pH的升高而增大.

关键词: 光敏热成像材料, 酞嗪, 感光性能

Abstract: The effect of components including tetracholrophthalic acid, phthalazine and antifoggant with tribromomethyl sulfone groups on photographic properties of FTG materials was investigated in different pH, using polyvinyl alcohol as a hydrophilic binder, in situ formed AgBr as light sensitive component. The results showed that fog and maximum density could be reduced obviously by using antifoggant; maximum sensitivity of PTG systems was obtained when pH was in the range of 7.0-7. 5; however, fog was elevating with the increasing of pH.

Key words: photothermographic materials, phthalazine, photographic properties
