GLASS, GLASS-CERAMIC AND CERAMIC ARTICLES WITH DURABLE LUBRICIOUS ANTI-FINGERPRINT COATINGS OVER OPTICAL AND SCRATCH-RESISTANT COATINGS AND METHODS OF MAKING THE SAME

Abstract:

An article is described herein that includes: a glass, glass-ceramic or ceramic substrate comprising a primary surface; at least one of an optical film and a scratch-resistant film disposed over the primary surface; and an easy-to-clean (ETC) coating comprising a fluorinated material that is disposed over an outer surface of the at least one of an optical film and a scratch-resistant film. The at least one of an optical film and a scratch-resistant film comprises an average hardness of 10 GPa or more. Further, the outer surface of the at least one of an optical film and a scratch-resistant film comprises a surface roughness (R.sub.q) of less than 1.0 nm.
