Abstract
A pearlescent pigment includes a ceramic flake coated with a metal oxide. The metal oxide is, preferably, an oxide of titanium, iron, tin, chromium1, zirconium or a combination thereof, and the refractive index of the metal oxide coating is preferably at least 0.5 higher than that of the ceramic flake. The pearlescent pigment may be included in a coating applied to a metallic or plastic surface to give the surface a lustrous or pearlescent optical effect.
