When this plate was exposed to ultraviolet light, it turned bluish-purple, but when exposed to light and left in a dark place, it quickly returned to its original colorless color. Furthermore, when the light resistance was examined by irradiating it with light for 20 hours using a fade meter, it showed exactly the same photochromic properties as before being placed in the fade meter, and was found to have excellent fatigue resistance.
