Abstract

See full text

Disclosed is an essentially solvent-based, organic, high-solids coating composition containing (A) a film-forming binder system containing a crosslinkable resin having a weight average molecular weight of from about 500 to about 10,000; (B) substantially colorless, substantially inorganic microparticles stably dispersed in the coating composition; and (C) a solvent system for the crosslinkable resin. The inorganic microparticles prior to incorporation in the coating composition range in size from about 1 to about 150 nanometers and are in the form of a sol of the microparticles in which carbon-containing molecules are chemically bonded to the inorganic microparticles at the surface of the microparticles.
