As shown in FIG. 4, it was found that the sample containing a large amount of titanium dioxide was particularly susceptible to discoloration and fading, and was significantly deteriorated. The photocatalytic action of titanium dioxide is 3
It is caused by UV irradiation in the wavelength range of 00 nm to 400 nm. It is considered that the reaction due to the photocatalytic action is accelerated by the active oxygen generated when the hydrogen peroxide solution is decomposed, and the resin portion on the sample surface is deteriorated. On the other hand, at the stage of deterioration in saturated water vapor in an oxygen atmosphere, the reaction portion is hydrolyzed, so that the reflectance changes and appears as a change in color difference.
