Anti-counterfeit fluorescent pigments, such as long wave (365nm) UV fluorescent pigments and short wave (254nm) UV fluorescent pigments, which are produced by special ways. These pigments are white, or pale yellow, or pale red while they glow bright red, yellow, green, and other colors. Long wave (365nm) UV fluorescent pigments can be excited by long wave UV light with 365nm wavelength, while short wave (254nm) UV fluorescent pigments can be excited by short wave UV light with 254nm wavelength.
