Abstract
The light deterioration behavior was examined by using the monochromatic light irradiation of Okazaki National Research Institutes of National Institute for Basic Biology Large Spectrograph (OLS) and all wave length irradiation for the examination material that was used piling suiting thin film of polyphenylene-ether (PPE) and polycarbonate (PC). The light deterioration depth was examined by using the piling suiting film, as a result light deterioration limit was confirmed. In addition, the quinone-methide structure generated to PPE and it was confirmed that coloring PPE with the influence of light was related to the quinone-methide structure. Absorbance on the irradiation surface was more remarkable absorption than other thin films. In an internal thin film was confirmed that the light deterioration material did not generate. Moreover, making to insoluble generation material of light irradiation was in rising tendency on rate of making to the insoluble on the irradiation surface. It was thought the making to insoluble material and the Quinone-methide structure thought to be a coloring cause was irrelevant. Fault photochemical reaction stopped by a certain thickness, it was thought that this was a reaction own defended by being deteriorated the material.
