The planar pattern is impressed in a backing (4) and is divided into M grid squares (6). Each grid square (6) is divided into N square portions (7), each square portion (7) being assigned to a pixel of one of N illustrations (3) and each having a diffraction element (8) which contains the information via a colour value, via a stage of the brightness value and via a viewing direction (15). The N illustrations (3) are composed of bundles of diffracted light and constitute, for example, individual alphanumeric characters, parts of text, views of objects or persons, etc., which are visible in the N viewing directions (15). The planar patterns can be viewed in reflection or transmission. The backing (4) can be constructed as an adhesive label. …<IMAGE>… |
