摘　　要：为了使人们从理论和实践上系统地把握彩色胶片冲洗成像过程并进一步提高彩色胶片影像的耐久性,有必要弄清彩色胶片档案影像形成中防光晕层的脱色处理方法。文章利用文献研究法梳理了国内现有档案保护、摄影等类文献中防光晕层脱色的主要观点并分析了其特点,然后介绍了在胶片背涂层、底层和片基等结构涂布吸光剂的防光晕方法,并以此为基础对彩色胶片防光晕层脱色处理方法和注意事项进行了再思考,包括炭黑防光晕层、胶体银防光晕层、染料防光晕层和有色片基的脱色处理。In order to make people grasp the process of development of color film systematically from theory and practice and further improve the durability of the image of color film,it is necessary to make clear the decolorization of anti-halation layer in the image formation of color film.Therefore,this paper uses the literature research method to sort out the main viewpoints about the decolorization of anti-halation layer in the existing domestic archives conservation,photography and other literature and analyzes its characteristics,and then introduces the anti-halation method of coating absorbents on the film back coating layer,coating substrate and film base,and the decolorization methods and their precautions of the anti-halation layer of color film are reconsidered,including the decolorization of carbon black anti-halation layer,colloidal silver anti-halation layer,dye anti-halation layer and colored film base.
