Abstract:
PROBLEM TO BE SOLVED: To provide a security element difficult to copy.SOLUTION: The security element includes a layer composite which has microscopically fine, optically effective structures 9 of a surface pattern, which are embedded between two layers 5;6. The microscopically fine, optically effective structures 9 is shaped into an interface 8 between two layers 5;6 in surface parts of a holographically non-copyable security feature in a plane of the surface pattern, which is defined by co-ordinate axes x and y. The optically effective structure 9 in at least one surface part is a diffraction structure (S;S*;S**) formed by additive superimposition of a macroscopic superimposition function (M) with a microscopically fine relief profile (R). The relief profile (R), the superimposition function (M) and also the diffraction structure (S;S*;S**) are functions of the co-ordinates x and y.

PROBLEM TO BE SOLVED: To provide an improved security element to safely protect a security document and the process for the manufacture of the same. SOLUTION: The invention concerns a security element 3' having a top side and an underside and a process for the manufacture thereof. The security element has a transparent layer 33' with a non-homogenous refractive index, in which a plurality of Bragg planes are formed by a refractive index variation. The transparent layer 33' is of a layer thickness of 5 to 200 μm and the transparent layer 33' has a plurality of first zones 41 of a smallest dimension of less than 300 μm, which are arranged in accordance with a first grid raster in a one-dimensional or two-dimensional succession in mutually adjacent relationship and in which the Bragg planes of the transparent layer are respectively shaped to provide a respective transmissive optical imaging function.
