- FIG. 3 reflection on a macro structure, 4 scattering on matt structures,
- Figure 5 shows the additive superimposition of the macrostructure 'with a
- 1 means a layer composite, 2 a security element and 3 a document.
- the security element 2 has a macro structure M in the layer composite 1, which extends in the area of a pattern 4.
- the security element 2 is arranged in an imaginary reference plane spanned by the coordinate axes x, y.
- the macro structure M is a unique, piecewise continuous and differentiable function M (x, y) of the coordinates x, y.
- the function M (x, y) describes a surface that is curved at least in partial areas, wherein ⁇ M (x, y) ⁇ 0 applies in partial areas.
- the macro structure M is a three-dimensional surface, where x, y are the coordinates of a point P (x, y) on the surface of the macro structure M.
- the distance z (x, y) of the point P (x, y) from the reference plane is measured parallel to the coordinate axis z, which is perpendicular to the plane of the drawing in FIG. 1.
- the pattern 4 is in an embodiment of a surface pattern 38 with the light-modifying structures known from EP 0 375 833 A1 mentioned at the outset, e.g. a flat mirror surface, light diffractive, microscopic lattice structures, matt structures, etc., surrounded.

- the line and mosaic elements advantageously have a dimension in the range of 0.05 mm to 1 mm in one direction.
- the security element 2 is transparent in an edge zone outside the pattern 4.
- FIG. 2 shows a cross section through the layer composite 1 glued onto the document 3.
- the layer composite 1 consists of several layers of Various plastic layers applied one after the other to a carrier film (not shown here) and, in the order given, typically comprises a cover layer 5, an impression layer 6, a protective layer 7 and an adhesive layer 8. At least the cover layer 5 and the impression layer 6 are transparent to incident light 9. The pattern 4 is visible through the cover layer 5 and the impression layer 6.
- the protective layer 7 and the adhesive layer 8 are also transparent, indicia (not shown here) attached to the surface of the substrate 3 can be recognized by transparent points 10.
- the transparent locations 10 are found, for example, within the pattern 4 and / or in the edge zone of the security element 2 surrounding the pattern 4. In one embodiment, the edge zone is completely transparent, in another embodiment only at predetermined transparent locations 10
- the cover layer 5 itself is, in another embodiment, the carrier film is used to apply the thin layer composite 1 to the substrate 3 and is then removed from the layer composite 1, as described in GB 2 129 739 A mentioned at the outset.
- the common contact surface between the impression layer 6 and the protective layer 7 is the interface 11.
- the optically active structures 12 of the macrostructure M of the pattern 4 (FIG. 1) are molded into the impression layer 6 with a structure height Hst. 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 can be formed by a metal coating, preferably from the elements in Table 5 of US Pat. No. 4,856,857 mentioned at the outset, in particular aluminum, silver, gold, copper, chromium, tantalum, etc., which separates the impression layer 6 and the protective layer 7 as the reflection layer.
- the electrical conductivity of the metal coating causes a high reflectivity for visible incident light 9 at the interface 11.
- one or more layers of one of the known, transparent, inorganic dielectrics are suitable, which are mentioned, for example, in Tables 1 and 4 of the introduction US 4,856,857 are listed, or the reflection layer has a multilayer interference layer, such as a two-layer metal-dielectric combination, a metal-dielectric-metal combination, etc.
- the reflection layer is structured, ie it only partially covers the interface 11 and leaves the interface 11 free at the predetermined transparent locations 10.
- the layer composite 1 is produced as a plastic laminate in the form of a long film web with a large number of copies of the pattern 4 arranged next to one another.
- the security elements 2 are cut out of the film web, for example, and connected to the document 3 by means of the adhesive layer 8.
- Documents 3 include banknotes, bank cards, ID cards or other important or valuable items.
- the macro structure M (x, y) is 4 of one or more for simple patterns
- Coordinate axis is x or y.
- the macro structure M (x, y) is periodically composed of a predetermined section of another mathematical function and has one or more periods in the partial area 13.
- the spatial frequencies F have a value of at most 20 lines / mm and are preferably below a value of 5 lines / mm.
- the dimensions of the surface part 13 are at least larger than 0.4 mm in one direction, so that details in pattern 4 can be seen with the naked eye.
- one or more of the partial areas 13 form a relief image as a pattern 4, the interface 11 following the surface of the relief image instead of the simple mathematical functions of the macro structure M.
- Models for pattern 4 can be found on gems or embossed images, such as seals, coins, medals, etc.
- the macrostructure M of the surface of the relief image is continuous and differentiable piece by piece and is curved in the partial areas.
- the macro structure M simulates other visible three-dimensional surface textures, for example textures of almost periodic meshes or fabrics, a large number of relatively simply structured bodies in a regular or irregular arrangement, etc.
- the list of macro structures M that can be used is incomplete, since a large number of macro structures M are piecewise continuous, differentiable and at least in partial areas ⁇ M (x, y) ⁇ 0 applies.
- the layer composite 1 must not apply too heavily on the document 3. On the one hand, the documents 3 would otherwise be difficult to stack 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 ⁇ m to approximately 100 ⁇ m.
- Impression layer 6 is only part of the layer composite 1, so that a structure height HST permissible in terms of the structure of the layer composite 1 for the macrostructure M molded into the impression layer 6 is limited to values below 40 ⁇ m.
- the technical difficulties in molding the macrostructure M increase with increasing structure height, so that preferred values for the structure height HST are less than 5 ⁇ m.
- Interface 11 is shown as an impression structure A molded into the impression layer 6 with the optically effective 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 extends along the coordinate axis z. Since the macrostructure M to be molded can exceed the predetermined value of the structure height HST, the profile height h of the macrostructure M must be limited to the predetermined stroke H of the impression structure A in each P (x, y) of the pattern 4.
- the macrostructures M with high values of the profile height h are also to be molded into the layer composite 1 which is only a few micrometers thick, whereby in the Impression structure A discontinuities 14 generated for technical reasons occur.
- the amount of the function C (x; y) is limited to a range of values, for example half the value of the structure height H S T-.
- the values for the stroke H can also differ locally in certain embodiments of the pattern 4.
- the locally varying stroke H is determined in that the distance between two successive discontinuities P n does not exceed a predetermined value in the range from 40 ⁇ m to 300 ⁇ m.
- the impression structure A between two adjacent discontinuities 14 is identical to the macro structure M except for a constant value. Therefore, with the exception of the shadow cast, the impression structure A produces the same optical effect as the original macro structure M to a good approximation.
- the illuminated pattern 4 thus behaves like the relief image or how when viewed while tilting and / or rotating the layer composite 1 in the reference plane a three-dimensional surface described by the macrostructure M, although the layer composite is only a few micrometers thick.
- Reflection layer is e.g. an approximately 30 nm thick layer of aluminum is used.
- Reflection layer is e.g. an approximately 30 nm thick layer of aluminum is used.
- the incident light 9 falls in an incidence plane 15 which is a normal 16
- Reference plane or to the surface of the layer composite 1 contains the optically active structure 12 in the layer composite 1.
- Parallel illuminating beams 17, 18, 19 of the incident light 9 meet surface elements of the impression structure A, for example at the points labeled a, b, c.
- Each of the surface elements has a local inclination ⁇ and a surface normal 20, 21, 22 in the plane of incidence 15, which are determined by the component of degree M (x, y).
- the local inclination is ⁇ ⁇ 0 °.
- Ein Observer 26 who looks in the direction of view 27, which lies, for example, in the plane of incidence 15, receives the reflected light of the rays 23, 24, 25 only with his unarmed eye if he is due to the tilting of the security element 2 (FIG. 1) or the layer composite 1 about an axis 28 lying in the reference plane and oriented perpendicular to the plane of incidence 15, which reflects at normal angles 16 at different angles -9, ⁇ -i, ⁇ 2 th rays 23, 24, 25 coincide with his viewing direction 27.
- the observer 26 sees the surface elements of FIG. 1
- Macro structure 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 interface 11 itself is smooth, the other surface elements of the macro structure M can also scatter some light parallel to the viewing direction 27 and appear to the observer 26 to different degrees depending on the local inclination.
- the observer 26 receives a plastic image impression, although the impression structure A is at most a few micrometers is high.
- Figures 4a and 4b show the different scattering behavior of the sub-area 13 of the security element 2 for the incident light 9. Die
- Matt structures have a microscopically fine, stochastic structure in the interface 11 and are described by a relief profile R, a function of the coordinates x and y.
- the matt structures as shown in FIG. 4a, scatter the parallel incident light 9 into a scattering cone 29 with an opening angle predetermined by the scattering capacity of the matt structure and with the
- Direction of the reflected light 23 as a cone axis The intensity of the scattered light is greatest, for example, on the cone axis and decreases with increasing distance from the cone axis, the light deflected in the direction of the surface lines of the scattering cone being just barely recognizable for an observer.
- the cross section of the scattering cone 29 perpendicular to the cone axis is rotationally symmetrical in the case of perpendicular light incidence in a matt structure called "isotropic" here. If, as shown in FIG.
- the cross-section of the scattering cone 29 is compressed, ie elliptically deformed in a preferred direction 30, the short main axis of the ellipse being aligned parallel to the preferred direction 30, the matt structure is referred to here as "anisotropic".
- the cross section of the scattering cone 29 in both the “isotropic” and the “anisotropic” matt structure, which is arranged parallel to the reference plane, is noticeably distorted in a direction parallel to the plane of incidence 15 (FIG. 3) when the angle of incidence ⁇ to the normal 16 is greater than 30 °.
- the relief structure elements are parallel aligned to the preferred direction 30.
- the "isotropic" matt structures have direction-independent statistical parameters and therefore have no preferred direction 30.
- the reflection layer consists of a colored metal or the cover layer 5 (FIG. 2) is colored and transparent.
- the use of one of the multilayer interference layers on the interface 11 is particularly effective, since due to the curvatures of the macrostructure M, the interference layer is of different thickness in the direction of the viewing direction 27 and therefore appears in locally different colors depending on the tilt angle 28.
- An example of the interference layer comprises a 100 nm to 150 nm TiO 2 layer between a transparent metal layer of 5 nm Al and an opaque metal layer of approximately 50 nm Al, the transparent metal layer facing the impression layer 6.
- FIG. 5 shows a cross-section through the layer composite 1 of a further embodiment of the macro structure M.
- the macro structure M is at least partially overlaid with a submicroscopic diffraction grating 31 in a partial area 13 (FIG. 4a).
- the diffraction grating 31 has the relief profile R of a periodic function of the coordinates x (FIG. 2) and y (FIG. 2) and has a constant profile.
- the submicroscopic diffraction grating 31 diffracts the incident light 9 (FIG. 4a) only into the zeroth diffraction order, ie in the direction of the beam 23 (FIG. 3) of the reflected light, in a section of the visible spectrum which is dependent on the spatial frequency f.
- FIG. 6 shows the cross section through the layer composite 1 with a further embodiment of the security element 2 (FIG. 2).
- the security element 2 comprises at least two partial surfaces 13 (FIG. 4a) which are arranged one behind the other in the drawing in FIG. 6.
- the constant K is the amount of curvature of the macrostructure M.
- Macrostructure M, degrees (M), in the surface parts 31, 32, 33 are aligned essentially parallel to the y / z plane.
- the gradients and therefore the strips 34 are parallel.
- the width of the strips 34 depends on the local curvature K and the nature of the interface 11 (FIG. 2) of the impression structure A used. With the same amount of curvature, the strips 34 are for the reflecting interfaces 11 rather narrow compared to the strip 34 of the interfaces 11 with the microscopic matt structure. Outside the strips 34, the surface parts 31, 32, 33 are visible in a shade of gray.
- a section along a track 37 is the cross section shown in FIG. FIG. 7b shows the security element 2 after rotation about the
- This predetermined tilt angle is determined by the choice and the positioning of the macrostructures M.
- a predetermined sign can only be seen on the surface pattern surrounding the pattern 4 if the strips 34 have a predetermined position, e.g. assume the position shown in the drawing Figure 7b, i.e. when the observer 26 (FIG. 3) observes the security element 2 under the viewing conditions determined by the predetermined tilt angle.
- the embodiments of the pattern 4 described above can be combined with one another, the correspondingly shaped macrostructures M with the curved mirror surfaces and the
