The present invention pertains to privacy film that can be used with
documents. The privacy film has a light transmissive, polymeric base
sheet that has opposing first and second surfaces. A plurality of light
directing elements protrudes from the first surface of the base sheet.
The base sheet can be constructed of a first polymeric material. The
light directing elements can be constructed of a second polymeric
material. The first and second polymeric material may be the same
material. The light directing elements are substantially constant in its
cross-section dimension and disposed substantially parallel to each
other.
