Patent ID: 7384695

Claim:
A substrate having a transparent, abrasion-resistant coating formed by the use of a coating composition comprising: a) the hydrolysis product of an epoxy-functional alkoxy silane, b) a curing agent for polymerizing epoxy compounds, the curing agent comprising a cationic photoinitiator selected from the group consisting of salts of Group Va elements, salts of Group VIa elements, and salts of Group VIIa elements, c) an ethylenically unsaturated monomer selected from the group consisting of acrylic monomers and oligomers having acrylic functionalities of not greater than two and photoactivated free-radical initiator therefore, and d) a viscosity-reducing amount up to 50% by weight, solids basis, of an unhydrolyzed epoxy-functional alkoxy silane, wherein the silanes of parts a) and d) are separately prepared and blended to form the composition and the composition is photocurable and wherein the silane of part a) is added in an amount sufficient to provide a concentration in the composition, based on weight (solids basis), of between about 10% to about 75%, and the silane of part d) is added in an amount sufficient to provide a concentration of not less than about 10%.
