ABSTRACT:
A composite including a polymeric film having a first generally planar major surface and an opposite second major surface defined by a multiplicity of elongate parallel contiguous ridge portions. The ridge portions each have a generally triangular cross section and elongate obscured and transmitting second major surface portions intersecting at the apex of the ridge with the obscured second major surface portion being on the side of the ridge generally facing a first end of the sheet and the transmitting second major surface portions being on the side of the ridge portions adjacent a second end of the sheet. The film can provide visual transmission between its first major surface and the transmitting second major surface portions while coatings along the obscured second major surface portions prevent viewing of visual images through the film; whereas the composite can also provide light transmission between the first major surface and the transmitting second major surface portions, while the coatings along the obscured second major surface portions restrict light transmission.
