Abstract
A fluorescent pigment includes a fluorescent dye and a resin carrier which is the polyamide reaction product of a diamine and a diacid. The fluorescent pigments are especially useful to color plastics and have improved resistance to plateout during molding. The pigments may be melt-blended with plastic to provide a color concentrate. The polyamide resins have a molecular weight in the range of 3,000 to 50,000 and may be readily ground to micron sized particles.
