摘要：
This invention relates to a two layers or more anti-static film coating deposited on a substrate. Selected layers of the films may have anti-static and/or electromagnetic properties. In one embodiment, the film farthest from the substrate has an index of refraction lower than the underlying film. In another embodiment, the surface of the film is roughened to provide a graded index of refraction.
