Abstract
The present invention relates to a data carrier, in particular an identity card, paper of value or the like, having applied thereto a plane element (OVD) with optically variable effects which are dependent on the viewing angle. Within at least a predefined area of the OVD there is additional information provided between the OVD and the surface of the data carrier in the form of characters, patterns or the like which, subsequently incorporated into the OVD, overlays the optically variable effect of the OVD and is likewise visually recognizable. The invention also relates to a method for producing such a data carrier.
