Methods for preparing multi-layer optical laminates include placing an optical film that is free form an adhesive layer between first and second glass substrates that are free of an adhesive layer, placing this laminate under vacuum, and then heating the laminate under pressure to a temperature above the softening temperature of the optical film. The glass substrates are free of an adhesive layer but may include a silane surface treatment. The resulting multi-layer laminate is optically clear and does not show scattering of reflected light by the optical film.
