| 摘 要： | 主要研究了在一定温度、一定阶段加入Zn (Ⅱ ) EDTA超增感剂对卤化银乳剂照相性能的影响。通过对比试验发现 ,用Zn (Ⅱ ) EDTA进行超增感的乳剂 ,感光度、反差等照相性能都有很大提高。结果表明卤化银成像体系中 ,在乳化开始阶段加入适量的超增感剂Zn (Ⅱ ) EDTA ,能起到显著的增感效应。对其超增感作用机理作了初步的分析探讨。

| Abstract: | Effects on the photographic properties of silver halide emulsion by adding additional sensitizing agent, Zn(Ⅱ)-EDTA,have been investigated.Results from the contrast test showed that photographic properties such as light sensitivity,contrast ratio were improved when Zn(Ⅱ)-EDTA was added in the preliminary emulsifying step.The mechanism was discussed. |
