Flourscent pigment

Fluorescence is a photoluminescence process. In this process, the short wavelength electromagnetic waves in the ultraviolet or visible light band are absorbed and released in the form of long wavelength electromagnetic waves. The latter usually falls within the visible range, superimposed with conventional reflected light, thus showing dazzling fluorescent colors.

The difference between fluorescent pigments and traditional pigments is not only in color, but also in chemistry. Traditional pigments can be organic or inorganic, with very low solubility. Their dispersion usually requires strong shear. Their particles are usually opaque. Daylight fluorescent pigments are strictly speaking, fluorescent dyes in the brittle polymer resin in the formation of solid solution. The latter is ground into fine powder and become a pigment or colorant. The characteristics of its solid solution make it often transparent in applications.
