Abstract: A pigment is disclosed wherein the pigment includes a platy substrate or uniform platy substrate coated with an odd number of layers of alternating layers of high or low refractive index material, wherein each layer has a refractive index that differs from adjacent layers by at least 0.2; and the pigment has from about 40 to about 100% reflectance of light having a wavelength of 280 nm to 400 nm. Processes for making and using the pigments are also disclosed. These pigments can find application in paints, plastics, cosmetics, glass, printing inks, and glazes.
