Patent ID: 8865786

Claim:
A coating composition comprising: at least one (meth)acrylate-functional silicon alkoxide, silica particles, at least one (meth)acrylate monomer, at least one epoxy (meth)acrylate oligomer, at least one photoinitiator, at least one solvent, at least one acid, and water; wherein the at least one epoxy (meth)acrylate oligomer has a concentration in the coating composition of about 0.25% by weight; and wherein the relative amounts of the constituents of the coating composition are controlled such that, when the coating composition is dispensed onto the surface of an article and cured, to form a coating having a thickness in the range of 10 to 200 nm, the coating has a refractive index less than 1.60 at a wavelength of 510 nm and exhibits a passing level of adhesion.
