Ultraviolet-excited fluorescent anti-counterfeiting ink is an ink made of inorganic pigments or organic dyes that can be excited by ultraviolet light to display colors, called fluorescent inks (or invisible inks). Its manufacturing method is to add the pigment (dye) to a certain proportion of resin oil linking material, filler, stabilizer and desiccant, and process it with an ink-making three-roller mill.
