Patent ID: 7002746

Claim:
A security element for verifying a document, comprising a layer composite which is disposed in a reference plane defined by co-ordinate axes (x; y), wherein the layer composite comprises plastic material layers with embedded optically effective structures which form a pattern and which are shaped in surface portions of the pattern into a transparent shaping layer of the layer composite and form a reflecting interface embedded between the transparent shaping layer and a protective layer of the layer composite, wherein in at least one surface portion of dimensions in at least one direction of greater than 0.4 mm as an optically effective structure a three-dimensional surface of at least one macrostructure is shaped into the reflecting interface, which has adjacent extreme values which are at least 0.1 mm away from each other, wherein a structural height is limited to values below 40 μm, and the at least one macrostructure of the reflecting interface which is curved at least in partial regions is an at least portion-wise steady and differentiable function of the co-ordinates (x; y) and is not a periodic triangular or rectangular function.
