Abstract 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. L'invention concerne un film de protection qui peut être utilisé avec des documents. Le film de protection se compose d'une feuille de base polymère qui transmet la lumière et qui possède une première et une deuxième surface opposée. Une pluralité d'éléments d'orientation de la lumière dépasse de la première surface de la feuille de base. La feuille de base peut être constituée d'un premier matériau polymère. Les éléments d'orientation de la lumière peuvent être constitués d'un deuxième matériau polymère. Le premier et le deuxième matériau polymère peuvent être constitués du même matériau. Les éléments d'orientation de la lumière sont sensiblement constants dans leur dimension transversale et sont disposés sensiblement parallèlement l'un par rapport à l'autre.
