Abstract: 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.

Abstract: An optical assembly including a first optical substrate including a first major surface; a multilayer polymeric optical film disposed on the first major surface of the first optical substrate and including a plurality of polymeric layers numbering greater than about 50 in total; and a first optical bonding layer having an average thickness of less than about 0.5 microns and disposed between, and making physical contact to, the first major surface of the first optical substrate and the multilayer polymeric optical film, the first optical bonding layer bonding the first optical substrate to the multilayer polymeric optical film and including a silanated amine.

Abstract: A member peeling method includes a step for preparing a first member having a first main face and an outer edge thereof and a second member having a second main face and an outer edge thereon, a step for disposing a photothermal conversion layer on at least one portion of the outer edge on the first main face, a step for mutually joining the first main face and the second main face via an adhesive layer, a step for irradiating a laser light to the photothermal conversion layer, and a step for at least partially peeling the first member from the second member by applying a force to an outer peripheral portion of either of the first member or the second member in a direction away from the other member.
