Abstract: An optical film including a thermoplastic birefringent multilayer optical film and a UV-cured layer disposed adjacent an outer layer of the multilayer optical film is described. The outer layer has a thickness in a range of about 0.5 micrometers to about 1.0 micrometers and the UV-cured layer includes a structured surface opposite the outer layer. The UV-cured layer has a Tg less than about 30° C. and has a pencil hardness in a range of 2B to 2H.
