Abstract (en)
[origin: WO03095221A2] A security document such as a banknote, comprising an optical security area (3) which consists of a first periodic optical structure, e.g. parallel grid-type lines, a parallel line grid or point grid (1), and which contains a security sign (5) whose contours encompass a second, periodic optical structure, e.g. parallel grid-type lines, a parallel line grid or point grid (2) which is arranged in an offset manner in relation to the first. The recognizibility of the security sign (5) is increased by observation with the aid of a see-through element (4), said element (4) being applied to an area of the security area (4) in such a way that the area of the security sign contained in the area covered by the see-through element (4) can be recognized by the naked eye.
