染料在卤化银感光材料中应用十分广泛。前期讲座介绍了增感染料和成色剂(由其在彩色显影过程中形成染料),均是重要的补加剂。除了成色剂能够作为构成彩色照相的原料外,在染印法、银漂法和扩散转移法感光材料中也是以染料作为成像的直接材 Dyes are widely used in silver halide photographic materials. Pre-lectures introduced sensitizing dyes and couplers (which form dyes during color development), both of which are important additives. In addition to the coupler can be used as a raw material constituting color photography, dye printing method, silver drift method and diffusion transfer method photosensitive material is also used as a dye image of the direct material
