| 摘 要： | 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Mg2+、Zn2+、Fe3+和Cu2+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Cu2+和Fe3+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。Mg2+和Zn2+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。

| Abstract: | The influence of Mg2+,Zn2+,Cu2+ or Fe3+ ions,in corporated individually during coupler dispersion,on each reaction of dye formation in a color photographic system containing incorporated coupler were investigated in this paper.The experimental results showed that Cu2+ or Fe3+ decrease the sensitivity of the emulsions,but increase the rate of reaction for the conversion of the leuco-dye to dye,Mg2+ or Zn2+ decrease the coupling efficiency of coupler (I).Consequently,Mg2+,Zn2+,Cu2+ or Fe3+ incorporated in the coupler dispersion decrease more ro less the photographic sensitivity of photographic layer containing incorporated coupler. |
