亚硫酸盐对彩色成像过程的影响

INFLUENCE OF SULFITE ON THE COLOR IMAGING PROCESS

研究了彩色显影液中亚硫酸钠对含内偶青成色剂的卤化银单层片的彩色成像过程的各化学反应、青染料影像的有害吸收以及染料云形态的影响,结果表明亚硫酸钠能(1)提高银影像的形成速度;(2)降低成色剂的表观偶合效率;(3)增加青染料影像的有害吸收;(4)使染料云缩小并且使染料云的分布变窄。

The influences of sulfite in color developer on the color image formation process in an incorporated cyan coupler photographic system were investigated. The results indicated that sulfite can promoted the formation of silver image, but it decreased the apparent coupling efficiency of the coupler and increased the unwanted absorption of cyan dye image. The influences of sulfite in color developer on the microscopic structure of the dye cloud were also observed.
