COMPOSITE USED FOR LIGHT CONTROL OR PRIVACY

PROBLEM TO BE SOLVED: To provide an inexpensive and lightweight light control composite and privacy composite. SOLUTION: The composite comprises a polymeric film having a first generally planar major surface and an opposite second major surface defined by a multiplicity of elongate parallel continuous 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, the obscured second major surface portion generally faces a first end of the sheet on the side of the ridge and the transmitting second major surface portions is adjacent to a second end of the sheet on the side of the ridge portions. The film can provide visual transmission between the 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.
