Uv fluorescent pigment for anti-falsification printing
Introduction
UV fluorescent pigment itself is colorless, and after absorbing the energy of the ultraviolet light (uv-365nm or uv-254nm), it rapidly releases energy and exhibits a vivid color fluorescent effect. When the light source is removed, it stops immediately and back to the original invisible state.
