Optical brighteners are colorless to weakly colored organic compounds. When present on a substrate, optical brighteners absorb primarily invisible ultraviolet light in the 300-400 nanometer (nm) range and re-emit in the visible violet-to-blue fluorescent light to yield a brighter, fresher appearance. They are designed to brighten colors or mask yellowing in plastics, lacquers, paints, inks, photo-processing solutions and fibers.
