This article discusses fluorescent pigment applications, shifting towards safer and better-performing products.
Ninety nine percent of current fluorescent pigments are solid solutions of fluorescent dyes in resins. The pigment performance depends on the resin (major impact), the dye, and the interaction and the physical or chemical bonding between the utilized dyes and the resins. Since their market introduction, fluorescent pigments have always been stir-in pigments. Despite this main advantage, older generations of fluorescent pigments have been faced with different disadvantages (Table 1).
