Application
It is used as photochromic dye, which is a series, they are special small molecular materials which
change color under ultraviolet light. These dyes also change color excellently under the sun. Its
mechanism of color-change stems from the fact that the dye is excited by ultraviolet light, the molecular structure changes, thus resulting in color changes, and when ultraviolet light is removed, the molecular structure of the dye returns to its original colorless state. Photochromic dye are available in a variety of colors, such as purple, blue, yellow, pink, green, and so on, which can be mixed with different color dyes to effect more diverse color changes, such as red, brown, gray.
