Abstract: The main study methods and present research conclusions of photofading of organic dyes were reviewed in this paper.The processes of photooxidation and photoreduction,factors, typical reaction procedures,and study means were systematically discussed.The methods to improve the light fastness by designing the structures of dye molecules and using additives were introduced.

Key words: dye, light fastness, photofading, photooxidation, photoreduction
