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