| 摘 要： | 本文综述了近些年来，在采用改变多层彩色胶片乳剂层排列结构的新途径，以提高彩色负片的感光度。着重介绍了通过在分色感光层的下面，再涂一层卤化银颗粒较细小的乳剂层，引起漫反射光提高该分色感光层感光度的原理和实效。文中详细地阐明了下层乳剂层的厚度和卤化银颗粒大小对上层乳剂层感光度的影响。

| Abstract: | This paper presents a review on the advancement achieved in recent years for increasing the speed of color negative film by a new means of modifying the arrangement of emulsions layers in multi-layer color film. Mainly is described the principle and practical effect of increasing the speed of a color separation emulsion layer by means of coating closely an emulsion sub-layer containing fine AgX grains, which reflects diffuse light upon the front color separation layer, thus increases its speed. The paper quoted datas showing in details the influence of the thickness of the emulsion sob-layer and its AgX grains size on the speed of the front emulsion layer. |
