Multilayer data carrier and a method for producing it
First Claim
1. A data carrier comprising an optically variable element exhibiting optical effects which are dependent on the angle from which the element is viewed and including a layer underneath the optically variable element, said layer having a surface roughness over at least part of its area which is beneath the optically variable element so that said roughness extends into the optically variable element and at least a portion of the optically variable element overlying said part of the area exhibits optical effects which are independent of the angle from which the element is viewed.

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.
