非银感光材料是相对于银盐材料而言的。一般摄影用感光材料都是在明胶溶液中,用溴、碘化钾与硝酸银反应沉析出卤化银感光物质,然后涂在纸或片基上面制得,当银盐接受光子后形成肉眼见不到的所谓潜影,然后经显影等多道工序的溶液加工,把潜影放大即得可见影象。由于这种材料主要 Non-silver light-sensitive material is relative to the silver salt material. Photographic materials are generally used in gelatin gelatin solution, with bromine, potassium iodide and silver nitrate reaction precipitated silver halide light-sensitive material, and then coated on top of the paper or film obtained when the silver salt photon to form the naked eye can not see The so-called latent image, and then developed by the multi-channel process such as solution processing, the latent image zoom that is visible image. Due to this material is mainly
