The effect of six phenylhydrazides (general formula: R-Ph-NH-NH-COR') on the photographic characteristics of silver halide emulsion has been studied. The results show that there are relations between the effect of infectious development and the structure of phenylhydrazides. Additionally, the effect and mechanism of contrast-promoting agents (alcohols and amine derivatives) has been investigated in detail. The fact indicates that it can not only eliminate the feed back inhibition effect which is caused by the...

The effect of six phenylhydrazides (general formula: R-Ph-NH-NH-COR') on the photographic characteristics of silver halide emulsion has been studied. The results show that there are relations between the effect of infectious development and the structure of phenylhydrazides. Additionally, the effect and mechanism of contrast-promoting agents (alcohols and amine derivatives) has been investigated in detail. The fact indicates that it can not only eliminate the feed back inhibition effect which is caused by the use of phenylhydrazide alone, but also accelerate the infectious development greatly and enhance the contrast and speed of photographic development when a little amount of contrast-promoting agent is added in PQ developer. Furthermore, the mechanism of infectious development and contrast-promoting action is explained more definitely on the basis of analyzing the reduction rection products and intermediates of phenylhydrazides by means of LC, GC-MS and ESR spectrometry.

研究了六种结构不同的酰基苯肼化合物(通式:R—PhNH—NH—COR′)对卤化银乳剂感光性能的影响。结果表明,感染显影作用程度与酰基苯肼的结构有密切的关系。另外本文还就反差促进剂(醇类化合物和胺类衍生物)的作用及其机理进行了较深入的研究。事实说明,显影液中加入反差促进剂,不但能消除单独使用酰基苯肼时出现的“自阻”效应,而且还大大促进了感染显影的进行,提高了乳剂的反差和感光度。同时,本实验在应用高压液相色谱、色-质联仪、顺磁共振等方法对酰基苯胼的还原反应产物及反应中间物进行分析的基础上,更加明确地解释了感染显影和反差促进的作用机理。

The properties and kinetics of the development of phenylhydrazide are disscussed. The process of inflective development is caused by the microdisturbance of a developed silver halide grain to adjacent grains, and the microdisturbance is interpreted from the theory of phase formation. The disturbance greatly decreased the critical free-energy △G(r) of the developable grain in the adjacent region and caused it denunishing the critical size of developable nuclei and forming the inflective development.

本文讨论了酰基笨肼(R—Ar—N_2H_4—COR)显影剂的显影性能及显影动力学特点。将酰基苯肼的感染显影过程归结为快速显影颗粒对临近颗粒的微区扰动,并以新相形成理论分析了显影中发生的微区扰动性质。这一扰动可强烈地降低临近区域中显影颗粒的显影临界自由能△G_(r)~*,使其临界显影核尺寸变小,引起感染显影
