Claim 1:
2. The multi-layer article of claim 1, wherein the article further comprises:
a second optical film with a first major surface and a second major surface; and
a third glass substrate with a first major surface and a second major surface, wherein the second major surface of the second glass substrate is interfacially bonded to the first major surface of the second optical film, wherein the interfacial bond between the second glass substrate and the second optical film is free from an adhesive layer, and wherein the second major surface of the second optical film is interfacially bonded with the first major surface of the third glass substrate, wherein the interfacial bond between the second optical film and the third glass substrate is free from an adhesive layer, and wherein each of the second major surface of the second glass substrate and the first major surface of the third glass substrate is a treated or untreated surface, wherein the treated surface comprises a silane coupling agent-treated surface, and wherein the multi-layer article is optically clear and does not show scattering of reflected light by the optical films.
