The invention relates to a multi-layer body (10) and to 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) lying 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 moulded into the second surface (232) of the first layer (23) in a first region (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 region (31) are varied, in the first region (31), pseudorandomly within a variation range predefined in each case for the first face region, and wherein a reflective, second layer (24) is applied to each of the facet faces. |
