Ultraviolet fluorescent pigment is a kind of special security printing pigment/ink,which emit visible light (400-800nm) after irradiated by ultraviolet light (200-400nm).

A:According to the different excitation wavelengths,it divided into short wave (254nm)and long wave(365nm) .

short wave (254nm):Excitation wavelength is 254nm

Long wave (365nm):Excitation wavelength is 365nm

B:According to the different color,it divided into three types: colorless, colored, and discolored. Colorless also called invisible fluorescent pigment, can display red, yellow, blue, and green colors, Colored fluorescent pigment can make the original color brighter; Changing color fluorescent can change one color into another color.
