ABSTRACT:
In one aspect, the invention features articles that include a substrate having a first surface and a second surface contiguous with the first surface. The first and second surfaces are non-coplanar. A first multilayer film is disposed on the first surface. A second multilayer film is disposed on the second surface. The second multilayer film is contiguous with the first multilayer film.
