Composite used for light control of privacy

A composite comprising:

• a flexible polymeric film having a generally planar first major surface, first and second opposite ends, and a multiplicity of elongate parallel contiguous ridge portions defining a second major surface opposite said first major surface, each of said ridge portions having an apex opposite said first major surface, and each having generally planar elongate obscured and transmitting second major surface portions intersecting at said apex and defining elongate v-shaped grooves having depths of less than 2 millimeters between the apexes of adjacent ridges with the obscured second major surface portions being on the sides of the ridge portions generally facing the first end of the sheet and the transmitting second major surface portions being on the sides of the ridge portions generally facing the second end of the sheet, the angle between said transmitting second major surface portions and an imaginary plane parallel to the first major surface and passing through the apexes of the ridge portions being in the range of 25 to 60 degrees, and the included angle between said transmitting and obscured second major surface portions at the apexes of said ridge portions being in the range of about 50 to 130 degrees,
• said film providing light transmission through and between said first major surface and said transmitting second major surface portions, and
• said composite including means along said obscured second major surface portions for restricting light transmission through said obscured second major surface portions so that said composite will direct light through the composite from objects adjacent the second major surface of the film only to persons looking at the objects from predetermined orientations relative to the first major surface of the film.
