Abstract: Colored coating compositions comprising a polymer binder and a sphere selected from porous metal oxide spheres formed from metal oxide particles and having an average porosity of from 0.10 to 0.90; polymer spheres formed from a multimodal distribution of polymer particles; or mixtures thereof, wherein the colored coating composition when dried, exhibits visible light absorbance at a wavelength range from 400 nm to 800 nm. The sphere has an average particle size diameter of from 1 micron to 5 microns, or from 3 microns to 5 microns and exhibits a structural color which may be angle-dependent or angle-independent.

Abstract: Coating compositions comprising a polymer binder and a sphere selected from porous metal oxide spheres formed from metal oxide particles and having, e.g., an average porosity of from 0.10 to 0.90; polymer spheres formed from a multimodal distribution of polymer particles; or mixtures thereof, are described herein. The sphere enhances the reflective characteristics of the coating compositions with respect to electromagnetic radiation. In particular, the coating compositions when dried, can exhibit UV reflectance, visible light reflectance, IR reflectance, or a combination thereof.
