摘要:
A security element with increased protection against forgery includes at least one first region with structures that reflect an image motif in different spatial regions, such that a moving image is produced for an observer when a light source is moved correspondingly and/or when the viewing angle is changed. When the light source is moved and/or the viewing angle is changed, a movement of the image motif occurs at the same time. Furthermore, an optical effect layer is provided which defines a second region. The structures are covered by the optical effect layer over their entire surface or partially.
