Studies on the decoloration of organic pigments have been examined by various researchers, however, only a few papers refer to molecular structure change. Visible ray irradiation tests using the weather-o-meter or mercury arc lamp, and the exterior exposure tests have been performed by various authers from different points of view. Dispersing the xenon-lamp light through quartz prism and measuring the fading rate for various wave lengths, the authers analized the molecular structure change of organic pigments by infrared spectrophotometry and we discussed the correlation between fading phenomenum and molecular structure change on the basis of experimental results. We investigated suppression effect using some anti-oxidants and ultraviolet absorption agents as a fading inhibition, and besides we investigated their mutual effects. We have obtained such an experimental result, that the sufficient suppresion effect can be expected by using together two inhibitions adequately selected.
