Photochromic Pigments

Photochromic Pigments Powder, also known as photosensitive pigment, undergoes a molecular structure change when exposed to sunlight or ultraviolet rays. They absorb the energy from sunlight and UV rays, leading to a shift in the absorption wavelength and resulting in a change of color. Once deprived of sunlight and UV energy, the Photochromic Pigments revert to their original molecular structure, restoring the initial color.
