<p>A highly refractive coating composition which can be stably preserved without losing the initial properties even after preserved for extended periods of time. The coating composition contains a metal oxide, a polymerizable alkoxysilane compound, a polymerization catalyst, an acidic aqueous solution and a solvent, wherein an organoamine compound is contained in an amount of from 0.05 to 1.3% by weight with respect to the metal oxide. A method of producing the coating composition comprises mixing a metal oxide suspension containing an organoamine compound in an amount of not smaller than 1.3% by weight with respect to the metal oxide, a polymerizable alkoxysilane compound, a polymerization catalyst, an acidic aqueous solution and a solvent, wherein the organoamine compound is removed so that the amount thereof is from 0.05 to 1.3% by weight with respect to the metal oxide contained in said metal oxide suspension.</p> |
