Abstract
Heat curable hard coat compositions are provided of aqueous colloidal silica and copolymer of an alkylacrylate and a polyalkoxysilylacrylate or a mixture of an alkylacrylate-acrylic acid copolymer and an epoxyalkoxysilane. The heat curable hardcoat composition can be applied onto various substrates, for example, a polycarbonate substrate, and thereafter heat cured to produce coated articles having adherent and abrasion resistant coatings.
