Abstract
A coating composition comprising a resinous binder and a color effect colorant in particulate form. The colorant includes an ordered periodic array of particles held in a polymer wherein a difference in refractive index between the polymer and the particles is at least about 0.01. The colorant reflects visible light according to Bragg's law to yield a goniochromatic effect to the coating composition.
