Claim 0:
1. A multi-layer article comprising:
a first glass substrate with a first major surface and a second major surface;
a second glass substrate with a first major surface and a second major surface; and
a first optical film with a first major surface and a second major surface comprising one or more layers of polymeric material, wherein the second major surface of the first glass substrate is interfacially bonded to the first major surface of the first optical film, wherein the interfacial bond between the first glass substrate and the first optical film is free from an adhesive layer, and wherein the second major surface of the first optical film is interfacially bonded with the first major surface of the second glass substrate, wherein the interfacial bond between the first optical film and the second glass substrate is free from an adhesive layer, and wherein each of the second major surface of the first glass substrate and the first major surface of the second 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 first optical film.
