White bodied powders for use in inks, paints, plastics and other applications, where their presence is not meant to be apparent under normal lighting conditions. Under long ultraviolet or short ultraviolet irradiation, these materials fluoresce brilliantly, with no afterglow once the irradiating source is removed. Ideal for security and identification. Many times stronger than inorganic equivalents, but not intended for prolonged outdoor exposure.

Application guidelines:

These pigments are soluble in some polar solvents, but better performance is usually obtained by milling into the base. Dispersing agents may be required in water based formulations. Stability is typical of organic compounds, but effective life may be extended by the use of UV absorbing overlacquers to block shorter incident wavelengths. These may be blended together, but do not blend with non-luminescent pigments, or dyes, or other opacifiers, which will quench the luminescent emissions.
