Optical stack comprising adhesive

摘要: Presently described are optical stacks comprising a first film plurality of structures an optically active portion designed primarily to provide gain and optionally in-active bonding disposed on surface bonded second with light-transmissive adhesive layer such that the penetrate separation is provided between surface. In one embodiment, exhibit combination high peel strength retained brightness, particularly after aging. The preferably comprises interpenetrating network reaction product polyacrylate component polymerizable monomer has elastic modulus ranging from 100 2000 MPa at 25° C.
