摘要 |
An ink can be substantially invisible under most lighting conditions, and only visible when excited by UV energy having a wavelength specific to the colorant. The ink can include a liquid vehicle and a fluorescent colorant. The fluorescent colorant can have an average particle size of less than about 200 nm. Such ink can be configured as an ink-jet ink.
