阿克发彩色80S是一种双色罩彩色底片,感光度20定。它比阿克发CNS彩底在锐度与颗粒结构上都有明显的改进。涂层从顶层起为感蓝乳剂层(含黄成色剂)、胶体银黄滤色层、带有黄色罩的二层感绿乳剂层(含品红成色剂)、一层红滤色层、二层带有红色罩的感红乳剂层(含青成色剂)。各层间都涂有隔层,包括胶体银防光晕层总共12层,总厚度为19.9微米。该片最突出的特点是为减少光晕扩散,在品红层与青层之间有红滤色层防止青光反射,改善了胶片的清晰度。下面是CNS与80S在解象力方面的比较(单位:线/毫米):
Akzo color 80S is a two-color cover color film, sensitivity 20 set. It has a significant improvement in sharpness and grain structure over Ackerfa’s CNS color base. The coating is a blue sensitive emulsion layer (containing yellow coupler), a colloidal silver filter layer, a two-layer green sensitive emulsion layer with a yellow cover (including magenta coupler), a red filter layer from the top, Red layer with a red cover red emulsion layer (including cyan coupler). The layers were coated with a barrier layer, including a total of 12 layers of colloidal silver anti-flare layer with a total thickness of 19.9 microns. The most prominent feature of the film is to reduce the halo diffusion, the red filter layer between the magenta layer and the green layer to prevent glare reflection, improve the clarity of the film. Below is a comparison between CNS and 80S in Soliton (unit: line / mm):
