<p>Coating compositions are disclosed that include an alkoxide of the general formula RxM(OR′)z-x where R is an organic radical, M is silicon, aluminum, titanium, and/or zirconium, each R′is independently an alkyl radical, z is the valence of M, and x is a number less than z and may be zero. The coating composition is cationically curable. Also disclosed are articles at least partially coated with a hard coat deposited from such a coating composition, methods for depositing a hard coat on at least a portion of a plastic substrate, and methods for improving the adhesion and abrasion resistance of a substrate.</p> |
