通过测量和计算彩色单层片中成色剂的照相活性、偶合效率以及漂白前银密度等参数,研究了在分散四当量成色剂青(Ⅰ)时掺入金属离子Mg~(2+)、Zn~(2+)、Fe~(3+)和Cu~(2+)对彩色青单层片的成像过程中各个化学反应的影响。本实验的结果表明,成色剂中加入的金属离子Cu~(2+)和Fe~(3+)对成像过程的初始反应中的Ag影像形成产生不利的影响,但它们能促进偶合过程中青(Ⅰ)与显影剂氧化产物作用所生成的隐色体转变成染料的速率。Mg~(2+)和Zn~(2+)的加入主要是对偶合过程中青(Ⅰ)的偶合效率产生不利的影响。上述原因的综合影响,最终降低了彩色单层片的感光度。
By measuring and calculating the photographic activity, the coupling efficiency and the silver density before bleaching in the monolayer color film, the effects of the metal ion Mg ~ (2 +), Zn Effects of ~ (2+), Fe ~ (3+) and Cu ~ (2+) on the chemical reactions in the imaging of monochromatic green sheets. The results of this experiment show that the metal ions Cu2 + and Fe3 + added into the coupler have an adverse effect on the formation of Ag images in the initial reaction of the imaging process, but they can promote the formation of Ag (I) The rate at which a leuco formed by the action of the developer oxidation product is converted to a dye. The addition of Mg 2+ and Zn 2+ mainly has an adverse effect on the coupling efficiency of cyan (Ⅰ) during the coupling process. The combined effect of the above reasons, eventually reducing the color monolayer sensitivity.
