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 moulded 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.

41. A multi-layer body with a first layer with a first surface and a second surface opposite the first surface, wherein the first surface of the first layer defines a base plane spanned by coordinate axes x and y, wherein molded into the second surface of the first layer in a first area are a large number of facet faces, wherein each of the facet faces has a minimum dimension of more than 1 μ
- m and a maximum dimension of less than 300 μ
m, wherein each of the facet faces is determined by the parameters;
form F of the facet face, area size S of the facet face, spacing H of the centroid of the facet face from the base plane, position P of the centroid of the facet face in the coordinate system spanned by the x-axis and the y-axis, angle of inclination Ax of the facet face about the x-axis towards the base plane, angle of inclination Ay of the facet face about the y-axis towards the base plane and azimuthal angle Az of the facet face defined by the angle of rotation of the facet face about a z-axis perpendicular to the base plane, wherein one or more of the parameters F, S, H, P, Ax, Ay and Az of the facet faces arranged in the first area is varied pseudorandomly within a variation range predefined in each case for the first area, and wherein a reflective second layer is applied to each of the facet faces, wherein the angles of inclination Ax and Ay of the facet faces in the first area are in each case determined according to an additive superimposition of the angles of inclination Ax and Ay determined by a function F(x,y) with the pseudorandom variation of the angle of inclination Ax and/or the angle of inclination Ay within the respective variation range predefined for the first area of surface, wherein the function F(x,y) is chosen such that it varies the angles of inclination Ax and Ay to generate an optically variable first item of information. - View Dependent Claims (42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75)
