摘要: 通过改变PQ型系列显影液的组分和浓度,使该系列显影液的显影特性从Lith型逐渐演变到超加合型。用循环伏安法对系列显影液中的对苯二酚氧化还原过程进行测量。证明了该系列显影过程所遵循的机理从Yule提出的Lith机理转变到Levenson的再生机理。电化学测量结果与Van Veelen的照相性能测定结果相一致。

Abstract: With changing the composition and concentration of developers, the behavior of PQ developers is transferred from Lith type to superadditive type. The development is also transferred from Yule’s mechanism to the regeneration mechanism. To support this transferred mechanism, the oxidation current measurements of hydroquinone were given in this paper by cyclo-voltam-metric measurements. The electrochemical measurements in the present paper are in good agreement with Van Veelen’s sensitometric measurements.

Key words: cyclic voltammetry, supcradditive development, Lith development, mechanism of development
