【摘要】 通过染料的极谱分析以及在乳剂中的应用试验 ,对文题化合物与 5 -甲基 -7-羟基 -1 3、4-三氮吲哚利嗪、氧 -硫海因二甲川份菁染料进行增感研究。结果表明 :该类化合物在乳剂中使用具有一定的增感作用与防灰雾作用。其增感作用与该类化合物的极谱半波氧化电位值有关 ,极谱半波氧化电位值低 ,光谱增感效果好。更多还原

【Abstract】 The optical sensitization of 2 thiobenzimidazolylsulfonylimidate and 5 methy1 7 hydroxy 1,3,4 triazaindolizine in combination with oxa thiohydantion dimethine merocyanine dye was studied by carrying out polarographic measurement of the compounds and performing practiacal testing of their sensitization effect in silver chloride emulsion,therein witnessed a definite sensitization and anti fog action.The efficiency of sensitization is connected with the polarographic half wave oxidation potential of the compounds:the lower is the oxidation potential,the higher is the photographic sensitivity of this system.更多还原
