At least the cover layer 5 and the impression layer 6 are transparent to incident light 9. Through the cover layer 5 and the impression layer 6 through the pattern 4 is visible.
  • the protective layer 7 and the adhesive layer 8 are also transparent, indicia not shown here, which are applied to the surface of the substrate 3, can be recognized by transparent locations 10.
  • the transparent areas 10 can be found, for example, within the pattern 4 and / or in the border zone of the security element 2 surrounding the pattern 4.

  • the interface 11 In the impression layer 6 are the optically active structures 12 of the macrostructure M of the pattern 4 (FIG. Fig. 1 ) molded with a structural height H St. Since the protective layer 7 fills the valleys of the optically active structures 12, that of the function M (x, y) describes the interface 11.
  • the interface 11 may be formed by a metal coating, preferably from the elements of Table 5 of the above-mentioned US 4,856,857 , in particular aluminum, silver, gold, copper, chromium, tantalum, etc., which separates the impression layer 6 and the protective layer 7 as a reflection layer.

  • the macrostructure M of the surface of the relief image is piecewise continuous and differentiable and is curved in the subareas.
  • the macrostructure M replicates other visible three-dimensional surface textures, for example textures
  • the listing of the usable macrostructures M is incomplete since a plurality of the macrostructures M is piecewise continuous, differentiable and at least in partial areas .DELTA.M (x, y) ⁇ 0 applies.
  • the layer composite 1 must not be applied too much on the document 3. On the one hand, the documents 3 would otherwise be poorly stackable and, on the other hand, a thick layer composite 1 would offer an attack surface for detaching the layer composite 1 from the document 3.
  • the thickness of the layer composite varies according to the predetermined application and is typically in the range from 3 .mu.m to about 100 .mu.m.
  • the impression layer 6 is only a part of the layer composite 1, so that a structure height H ST permissible for the structure macrostructure 1 molded into the impression layer 6 is limited to values below 40 ⁇ m.
  • the technical difficulties in molding the macrostructure M increase with increasing structural height, so that preferred values of the structural height H ST are smaller than 5 ⁇ m.
  • the boundary surface 11 is shown as an impression structure A molded into the impression layer 6 with the optically active structures 12 and a relief height h R.
  • the impression structure A is a function A (x; y) of the coordinates x and y.
  • the height of the layer composite 1 expands along the coordinate axis z. Since the macrostructure M to be mapped may exceed the predetermined value of the feature height H ST , in each P (x, y) of the pattern 4, the profile height h of the macrostructure M must be limited to the predetermined stroke H of the impression structure A.
  • the macrostructures M with high values of the profile height h are also to be formed in the layer composite 1, which is a few micrometers thick, wherein in the Abform Modell A for technical reasons generated discontinuities 14 occur.
  • the function C (x; y) is limited in terms of amount to a range of values, for example to half the value of the structure height H ST .
  • the values for the stroke H may differ locally.
  • the locally varying stroke H is determined by the distance between two consecutive points of discontinuity P n not exceeding a predetermined value in the range from 40 ⁇ m to 300 ⁇ m.
  • the impression structure A is identical to the macrostructure M between two adjacent points of discontinuity 14 up to a constant value. Therefore, with the exception of the shadow cast, the impression structure A produces to a good approximation the same optical effect as the original macrostructure M.

  • the normal 16 and the second surface normal 21 enter the angle ⁇ > 0 °.
  • the observer 26 sees the surface elements of the macrostructure M with a high surface brightness, which have the same local inclination ⁇ in the plane of incidence 15 or in planes parallel to the plane of incidence 15.

  • the reflective layer consists of a colored metal or the cover layer 5 (FIG. Fig. 2 ) is colored and transparent. Particularly effective is the use of one of the multilayer interference layers on the interface 11, since the bulge of the macrostructure M, the interference layer in the direction of view 27 different thickness and therefore appears in locally different, dependent on the tilt angle 28 colors.
