卤化银彩色成像体系中染料云形态的优化

本文为验证彩色卤化银体系中染料云形成的动力学模型而设计了实验,实验验证是采用一种“三明治”结构的彩色卤化银涂层,以保证其在曝光和彩色显影后所形成的染料云基本上不重叠,然后测量其染料云的尺寸分布和平均尺寸并与彩色卤化银体系中染料云形成的动力学模型计算所得的染料云的平均尺寸进行比较,结果证实了模型的适用性,在此基础上利用模型研究了各种因素对染料云形态、尺寸的影响,并综合各因素进行体系的优化。

OPTIMIZATION OF MORPHOLOGY OF DYE CLOUD IN COLOR SILVER HALIDE IMAGING SYSTEM

Experiments were designed to verify the kinetic model of dye cloud formation in color silver halide system. A coating structure in the form of "sandwich",in which an intermediate emulsion layer with AgX grains and coupler droplets was coated between an upper and a bottom gelatin layer with only dispersed coupler, was adopted to ensure the formed dye clouds were separated from each other after exposure and color development. The applicability of the model was confirmed by comparison between sizes of dye clouds measured and calculated. Then, taking advantage of the model, the optimizations for size and morphology of the dye clouds formed under many different factors were explored.
