(四)彩色感光材料乳剂涂布前的补加剂对于彩色感光材料,在乳剂涂布前,需要加入各种补加剂,如光学增感剂,成色剂、坚膜剂、表面活性剂等。一、增感染料高感光度碘溴化银乳剂的固有感光波长范围是350～530nm(主要是兰紫光),这种乳剂被称为色盲乳剂或非增感乳剂。摄影用的彩色胶片的感兰乳剂就属此类。 (D) of the color photosensitive material emulsion coating before the additive For color photosensitive material, before the emulsion coating, you need to add a variety of additives, such as optical sensitizers, couplers, hardeners, surfactants, etc. . First, the sensitizing dye high sensitivity iodine bromide silver bromide inherent sensitometric wavelength range is 350 ~ 530nm (mainly blue violet), this emulsion is called color-blind emulsion or non-sensitized emulsion. This is the type of sensitized emulsion used in color film photography.
