SECURITY DOCUMENT WITH STRESS COMPENSATED FOIL ELEMENT

摘要

The security document comprises a foil element (5) applied to a first side (6) of a substrate (1) as well as a counter layer (8) applied in the same lo-cation at a second side (7) of the substrate (1). The foil element (5) is over its entire extension bound to the substrate (1) and is comparatively thick. Counter layer (8) serves to reduce a tendency of the foil element (5) to cause a buckling of the substrate (1) and has blurred edges (10c, 10d) in order to decrease mechanical stress of the substrate (1) and visibility of the counter layer (8).
