Definitions
- the invention relates to an optically variable surface pattern which in the preamble of Claim 1 mentioned type.
- Such surface patterns contain structures, mostly microscopic in shape of fine relief structures that diffract incident light. These diffractive patterns are suitable, for example, as authenticity and security features for increasing security against counterfeiting. They are particularly suitable for the protection of Securities, banknotes, means of payment, identity cards, passports, etc.
- the function as an authenticity feature consists in the recipient of the provided object, e.g. a banknote to convey the feeling that the object is real and not a fake.
- the function as The security feature is to prevent unauthorized copying or at least to make it extremely difficult.
- Such surface patterns are known from many sources; be representative called EP 0 105 099 B1, EP 0 330 738 B1, EP 0 375 833 B1 here. she are characterized by the brilliance of the pattern and the movement effect in the pattern from, are embedded in a thin laminate of plastic and are in shape a mark on documents such as banknotes, securities, ID cards, Passports, visas, identity cards etc. applied, e.g. glued. For the production The materials that can be used for the security elements are in EP 0 201 323 B1 compiled.
- a pixel-oriented optically variable surface pattern is from the European Patent EP 0 375 833 B1 known.
- Such a surface pattern contains one predetermined number N of different images.
- the area pattern is in pixels subdividing. Each pixel is divided into N sub-pixels, with each of the N sub-pixels a pixel of one of the N images is assigned to a pixel.
- Any sub-pixel contains a diffraction structure in the form of a microscopic relief that Information about a color value, a level of the brightness value and about contains a viewing direction. Provides a viewer of the surface pattern only one image is shown at a time, with the respective visible image being tilted or rotating the surface pattern or by changing the viewing angle of the Viewer can be changed.
- Another optically variable surface pattern is from US Pat. No. 6,157,487 known.
- the microscopically fine Relief structures have a comparatively small number of lines per millimeter, so that incident light is almost achromatically diffracted.
- the invention has for its object an optically variable surface pattern propose that has improved copy protection.
- a diffraction-optically effective surface pattern comprises at least two Representations nested on the surface pattern are.
- the representations contain light diffractive, reflective structures that incident light under ordinary lighting conditions in bend different directions so that a viewer is only ever one of the Can see representations. By rotating and / or tilting the surface pattern or by changing the perspective, the viewer can do one or the other make another representation visible.
- the invention is now based on the idea of making the differences in the diffraction directions so small that on the one hand the representations from the viewer from a typical distance of 30 cm are perceptible separately and that on the other hand when copying using a color copier either all representations are copied so that on the Copy a picture that corresponds to the overlay of all representations, or that none of the representations are copied.
- Diffraction structures are preferably symmetrical or asymmetrical sawtooth-shaped relief structures are used, which are compared to the wavelength of the visible light a relatively long period, but different Have inclination angles.
- the period length can be used for the relief structures of all Representations be the same; but it can also be of different sizes.
- the Period length L is typically 5 ⁇ m or more. The bigger the Period length, the more the relief structure acts like an inclined mirror which reflects the incident light and is hardly bent anymore. That the Relief structure increasingly diffracts the light achromatically and the diffraction angle is determined by the law of reflection and diffraction and is for perpendicular striking light at least twice the angle of inclination.
- Diffraction structures can also be achromatic gratings with a Period length L of more than 5 ⁇ m and a sine-like relief profile, e.g. a sinusoidal relief profile can be used.
- the relief structures of the Different representations differ in the period length L and / or in the structure depth of the relief profile, so that the representations by the observer are perceptible separately.
- the diffraction structures can also be in the form of a Volume hologram can be realized.
- the surface pattern according to the invention can therefore be characterized by that the different representations when illuminated with perpendicular to the Surface pattern of light hitting a human viewer below different angles are perceptible separately, and that the difference the viewing angle of at least two of the representations is so small that one copy made by means of a copier the at least two representations reproduces one above the other.
- the directions of diffraction are from the given direction of illumination Orientation of the surface pattern depending. So when copying using a Color copier all regardless of the orientation of the surface pattern Representations can be copied onto the copy, several per representation Representations of the same content may be present by linear, but lattice structures rotated against each other are formed. Another solution is there in using circular grids as a grid.
- the entirety of the partial areas 6 includes the first graphic Representation 2, the entirety of the partial areas 7 includes the second graphic Representation 3 and the entirety of subareas 8 include the third graphic Representation 4.
- the dimensions of a field 5 are typically less than 0.3mm x 0.3mm, so that the individual fields 5 from the human eye at one Visible distance of 30 cm cannot be resolved.
- FIG. 2 shows the three representations 2, 3 and 4, which, for example, the lettering "100", “EUR” and represent.
- the lettering is light on a dark background (the reverse is true in the drawing).
- the representations 2, 3 and 4 are also subdivided into n * m grid fields 2.1, 3.1 and 4.1, which are either light or dark.
- the grid fields 2.1, 3.1, 4.1 are much too large compared to the lettering and, in addition, only some of the grid fields 2.1, 3.1, 4.1 are shown.
- a partial surface 6 (FIG. 1) is assigned to each grid field 2.1 of the first representation 2.
- a partial area 7 (FIG. 1) is assigned to each grid area 3.1 of the second representation 3
- a partial area 8 (FIG. 1) is assigned to each grid area 4.1 of the third representation 4.
- one of the grid fields 2.1 of the first representation 2 is dark, it contains the assigned partial area 6 a mirror or a cross grating with at least 3000 Lines per millimeter, which reflects, absorbs or reflects the incident light high angle is scattered. If one of the grid fields 2.1 is bright, it contains the assigned partial surface 6, as shown in FIG. 3, a sawtooth Relief structure 9.1.
- the relief structure 9.1 has a compared to the wavelength visible light has a comparatively large period length L, which is typically Is 5 ⁇ m or more.
- the first representation 2 (FIG.
- the furrows of the different relief structures 9.1, 9.2 and 9.3 run approximately parallel, i.e. the maximum difference in the angle that the furrows assume with respect to any axis in the plane of the surface pattern 1, the so-called azimuth angle, should be less than about 10 °, so below the lighting conditions prevailing when copying either all three or transfer none of representations 2, 3 and 4 to the copy become.
- the furrows preferably run parallel to a side edge of the object to be protected with the surface pattern so that the furrows are aligned as parallel as possible to the scanner of a color copier.
- the surface pattern 1 is, as shown in cross-section in FIG. 3, advantageously as Layered composite formed.
- the layer composite is formed by a first one Paint layer 10, a reflection layer 11 and a second paint layer, the Cover layer 12.
- the lacquer layer 10 is advantageously an adhesive layer, so that the Layer composite can be glued directly onto a substrate.
- substrate is for example a security, a banknote, an identity card, a Credit card, passport, or more generally an item to be protected meant.
- the cover layer 12 advantageously covers the relief structures completely on. It also preferably has an optical one in the visible range Refractive index of at least 1.5, so that the geometric profile height h a results in the largest possible optically effective profile height.
- FIG. 3 shows side by side the bright pixels of the three representations 2, 3 and 4 of FIG. 2 assigned sawtooth-shaped relief structures 9.1, 9.2 and 9.3, which are present in the corresponding partial areas 6, 7 and 8 of the fields 5 are.
- the human eye takes the representations 2, 3 and 4 separately true if the difference in the angle of inclination between each two adjacent representations is approximately 0.5 ° - 5 °.
- the value for the largest angle of inclination i.e.
- angle of inclination ⁇ should be at most 25 ° amount so that on the one hand the relief structures 9 do not become too deep and thus on the other hand, all three representations 2, 3 and 4 when copying using a Copier can be transferred to the copy.
- Fig. 4 shows schematically the geometric relationships when copying by means of a color copier 13.
- the color copier 13 has a glass plate 14 the document 15 to be copied, e.g. one banknote, one, and one in the x direction Mobile carriage 16 on which a light source 17, a deflecting mirror 18 and a detector 19 with photosensors 20 contains.
- Part of the incident light becomes approximately vertical thrown back to the glass plate 14, hits the deflecting mirror 18 and is thus the photosensors 20 of the color copier 13 are shown.
- the angles of inclination ⁇ , ⁇ and ⁇ are chosen such that the relief structures 9.1, 9.2 and 9.3 with correct orientation on the glass plate 14 of the color copier 13 reflect light emitted by the light source 17 onto the deflecting mirror 18. 5 shows this situation.
- Each of the representations 2, 3 and 4 is one associated sub-area 6, 7 or 8 on a very greatly enlarged scale shown, a bright point of the representation assigned to these partial areas is.
- the light beam reflected on the relief structure 9.1 has the reference symbol 22, the light beam reflected on the relief structure 9.2 has the reference symbol 23 and the light beam reflected on the relief structure 9.3 is with the Reference numeral 24 denotes.
- the mean angle of inclination is also the typical angle of 30 ° adjusted under which the light emitted by the light source 17 of the Color copier 13 falls on the document to be copied. This means that then the light diffracted at the associated relief structure approximately vertically is bent down to the deflecting mirror 18.
- a relief structure with circular furrows is shown in FIG. 7. The distance between two circular lines correspond to the period length L.
- asymmetrical relief structures 9.1, 9.2, 9.3 can also Relief structures with a symmetrical profile shape can be used incident light essentially not in one direction, but in two Reflect directions. Such an example is shown in FIG. 8. Also drawn is the angle ⁇ , which is the inclination of the relief structures 9 referred to the horizontal.
- the embodiment of the invention is not based on pixel-oriented surface patterns limited. 9 shows sections of an example of one not pixel-oriented surface pattern with two representations 2 and 3 that are not overlap.
- the area occupied by the surface pattern 1 is divided into three Subareas 6, 7 and 26.
- the subarea 26 serves as a common background for the two representations 2 and 3.
- the partial surface 6 contains sawtooth-shaped Relief structures which have a first angle of inclination and which are the light ones Create points of the first representation 2.
- the partial surface 7 contains sawtooth-shaped relief structures that have a second, from the first angle of inclination have different angles of inclination and the bright points of the generate second representation 3.
- the partial surface 26 is used to generate a dark or nondescript background. It is for example as a mirror or designed as a cross grid with at least 3000 lines per millimeter or transparent, so that at this point the substrate on which the surface pattern is glued on, is visible.
- the two representations 2 and 3 are thus from a human viewer can be perceived separately for a given direction of illumination because it is below different angles are visible.
- the angles of inclination are the sawtooth-shaped relief structures chosen so small that when copying using a copier both representations 2 and 3 are mapped onto the copy. On the copy, the two representations 2 and 3 are therefore visible without the Viewer must change the angle of view or the direction of illumination.
- the invention can be either as pixel-oriented according to the first embodiment Area pattern, or as not according to the above embodiment Realize pixel-oriented surface pattern, whereby the overlapping Areas are assigned to either the first or the second display.
- the surface pattern can also be a combination of the two Realize embodiments, the overlapping areas as in pixel-oriented surface patterns are executed.
