Colorless can show red, yellow, blue and green, etc., also known as invisible pigments; colored can make the original color brighter; color-changing can make one color change to another color. It is an ideal colorant for security inks.

Anti-counterfeiting fluorescent inks are also called UV-excited fluorescent anti-counterfeiting inks. This type of ink can be divided into colored fluorescent anti-counterfeiting inks and colorless fluorescent anti-counterfeiting inks. If we use colored fluorescent anti-counterfeiting inks to print charts or characters, we can see these icons and characters under normal light, and the fluorescent colors excited by ultraviolet fluorescent lamps are brighter. If we use colorless fluorescent anti-counterfeiting inks to print icons or characters, we cannot see these icons and characters under normal light, but fluorescent colors will be excited by ultraviolet fluorescent lamps.
