Abstract
Abstract A transparent optical film made of a polymeric material has a first smooth surface and a second structured surface for providing a simulated beveled appearance. The structured surface of the film is formed of a plurality of spaced parallel grooves, each groove being formed by a first facet which is substantially perpendicular to the first smooth surface and a second facet which makes an angle between 1 to 60 degrees with the first smooth surface. The film may be affixed to glass, the adhesive applied to the first smooth surface or the second structured surface, to simulate beveled glass. Further, a leaded glass appearance or beveled mirror appearance may be simulated by vapor coating the optical film.
