ABSTRACT:
A process for providing a metal oxide-containing coating on a compatible substrate, the coating being transparent to a photocuring source output and upon cure being resistant to electrical stress. The process of the invention comprises a) preparing a precursor composition comprising a mixture of a stabilizer and a metal oxide sol precursor material; b) combining the stabilizer/metal oxide sol precursor material mixture with a photocurable base resin without high shear mixing to achieve a homogeneous, transparent composition; c) coating the substrate material with the transparent composition; and d) photocuring the coated substrate bearing the transparent composition, wherein the cured coating is homogenous and transparent and remains transparent in the use state, thereby rendering the coating corona resistant. This invention further relates to the coated substrate.
