摘要： The invention is accomplished by forming balanced cyan, magenta, and yellow coupler and emulsion mixes. There is at least one layer in which silver halide emulsion has been sensitized to blue light or silver halide emulsion sensitive to green light. Regardless of the color sensitivity of the silver halide layer that contains silver contains a mix of cyan, magenta, and yellow dye-forming couplers. Further, in order to have a black-and-white image that has a lightness such as observed by the human eye in a scene, it is preferred that the ratios of red sensitive emulsion to green sensitive emulsion to blue sensitive emulsion in the photographic element is about 2:3:1.
摘要翻译： 本发明通过形成平衡的青色，品红色和黄色成色剂和乳液混合物来实现。 至少有一层其中卤化银乳剂已经对对绿色光敏感的蓝光或卤化银乳剂敏化。 不管含有银的卤化银层的颜色敏感性包含青色，品红色和黄色染料形成成色剂的混合物。 此外，为了具有在场景中由人眼观察到的亮度的黑白图像，优选的是，感光乳剂与感光乳剂对感光乳剂的比例在照相元件 约为2：3：1。
