COLORANT COMPOSITIONS AND METHOD OF MAKING

摘要

Colorant compositions include a transparent or translucent visible light colorant, a UV fluorescent pigment, and a UV blocking compound. Articles can be printed or coated with the colorant compositions. The colorant compositions have an appearance whereby the wavelength range of visible light viewable by the average human eye when a printed or coated article is irradiated by UV light at least partially overlaps with the wavelength range of the visible light viewable by the average human eye when the printed or coated article is irradiated by white light.
