多层彩色电影底片,除了其它的辅助层外,主要是由含黄成色剂感蓝光的卤化银乳剂层、含品红成色剂感绿光的卤化银乳剂层和含青成色剂感红光的卤化银乳剂层组成。根据减色法原理,形成相补的彩色影象。就卤化银乳剂本身而言,不论是溴碘化银型的乳剂,还是氯溴化银型的乳剂,仅对蓝、紫光线感光,为使这类乳剂也对其他颜色的光线,例如绿光、橙光、黄光、红光等光线也能感光,并把相应颜色的影象记录下 Multilayer color film negatives, among other auxiliary layers, are mainly composed of a silver halide emulsion layer containing a blue coupler-sensitized blue light, a silver halide emulsion layer containing a magenta coupler-sensitized green light, and a red-sensitive Silver halide emulsion layer. According to subtractive principle, a complementary color image is formed. With respect to the silver halide emulsion itself, whether it is a silver bromoiodide emulsion or a silver chlorobromide emulsion, only the blue and violet rays are sensitized, so that such emulsions are also sensitive to other colors of light such as green light, orange Light, yellow, red and other light can be photosensitive, and the corresponding color images recorded
