    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.

    Abstract: The invention relates to a multi-layer body (10) and a process for the production thereof. The multi-layer body has a first layer (23) with a first surface (231) and a second surface (232) opposite the first surface (231). The first surface (231) of the first layer (23) is defined by a base plane spanned by coordinate axes x and y, wherein a large number of facet faces (50) are molded into the second surface (232) of the first layer (23) in a first area (31). Each of the facet faces (50) is determined by one or more of the parameters F, S, H, P, Ax, Ay and Az, wherein the parameters of the facet faces (50) arranged in the first area (31) are varied pseudorandomly in the first area (31) within a variation range predefined in each case for the first area of surface and wherein a reflective second layer (24) is applied to each of the facet faces.
