摘要
本文研究了五种苯酰肼化合物（通式为Ｒ－Ｐｈ－ＮＨＮＨ－ＣＯＲ’）对卤化银乳剂感光性能的影响。利用循环伏安、气－质联仪等方法研究了苯酰肼感染显影的作用机理及其影响因素。实验结果表明，通过苯酰肼的感染显影可获得高感、高反差的效果，影响感染显影程度的大小，除了与取代基Ｒ，Ｒ’结构有密切关系以外，还与乳剂的种类、胶银比、苯酰肼在卤化银颗粒上的吸附等因素有一定关系。另外也发现苯酰肼衍生物取代基结构不同，其作用机理也不尽相同，从而进一步加深了对感染显影机理的认识。
The effects of five phenylhydrazines (general formular:R-Ph-NHNH-COR’)on thephotographic properties of silver halide emulsions have been investigated.The mechanismsand influential factors are also studied by cyclic voltammetry and GC-MS spectrometryetc,It is found that the infectious effects caused by phenylhydrazines vary with the changeif the substituent R or R’,and have a relation to the gelatin-silver ratio and the type of the emulsion.When the substituent R or R’was changed,the mechanism is different.A more complete understanding of the meachanism of infectious development has been obtaind.
