Description
Technical field
The present invention relates to a kind of optically variable element, in particular for the Security element of data medium.
Background technology
Data medium, such as face amount thing, identity document or the object of value (such as brand objects), conventionally have the optically variable element for security purpose, described optically variable element allows the authenticity of checking data carrier, simultaneously for defending unwarranted copying.For this reason, the optical effect of optically variable element changes when for example direction of observation changes, and can not be copied by conventional duplicator.
Summary of the invention
Under these prerequisites, the present invention is based on a kind of optically variable element of explanation, in particular for the object of the Security element of data medium, this optically variable element combines high resistance and forges property and good recognizability and simple verifiability.
This object is passed through optically variable element, Security element in particular for data medium is realized, this optically variable element has substrate, substrate has pattern forming section, pattern forming section has first region and second portion region, first makes by intaglio printing in region, does not make by intaglio printing in second portion region, wherein, two subregions can be perceived as respectively outstanding and/or retraction optically, First subregional can optics perception the marking and the marking coupling can sense of touch detecting, and second portion region can optics perception the marking and the marking can sense of touch detecting do not mate.
Therefore, a kind of optically variable element is provided, due to the outstanding and/or retraction optically of described subregion, this optically variable element is optically very attracting, wherein, surprisingly, the marking can sense of touch the detecting marking that only coupling can optics perception for first region rather than second portion region.The sense of touch of pattern forming section or the variation of palpable perception produce high identification value, and cause the authenticity of checking optical variable element simply.
Be perceived as subregion outstanding and/or that retract optically and be understood as especially at this region that each several part region is perceived as continuous protrusion.Therefore, subregion perceives as on can optics has protrusion, and this protrusion departs from curve or the real space shape in the reflecting layer in the region in appropriate section region.Especially the in the situation that of second portion region, can for example simulate by imitating corresponding reflex behavior the surface of corresponding protrusion.
Two subregions can be configured to respectively continuum.Yet subregion also can have gap or even comprise discontinuous part.Especially, two subregions can be interlaced with each other and/or staggered with other anti-counterfeiting characteristic.
And in two subregions one can be around another in two subregions.
In optically variable element, pattern forming section in second portion region can have a plurality of minutes faces, and described a plurality of minutes faces are orientated to existence for beholder and can optics be perceived as the region that macrospace shape with respect to the pattern forming section in second portion region is outstanding and/or retract.The in the situation that of second portion region, can simulate thus actual protrusion surface (reflection and/or transmission).Yet, the in the situation that of second portion region, also can imitate format surface, its reflex behavior can not protrude surface by reality to be caused.This region refers to " imaginary area " hereinafter.For example, this imaginary area can be perceived as revolving mirror, and it makes for example 90 ° of visible mirror image rotations.For beholder, be extremely easy to this imaginary area of optical detection and verification and especially this revolving mirror.
In principle, any actual reflection or transmission surface of protruding can be modified as imaginary area by the second portion region of optically variable element of the present invention.This can for example for example, realize by changing the azimuth (rotating to an angle) of all minutes faces.This can obtain attractive effect.For example, if all azimuths to 45 ° of right rotations, when directly throwing light on from top, imaginary area is obviously from the raised zones of beholder's top right side illumination.If all azimuths half-twist, light is reflected in when the vertical direction of the direction desired with beholder tilts and moves.For example, this non-natural reflex behavior also makes perceived area that beholder no longer determine to protrude (with respect to substrate) still backwards forward so.
And, in optically variable element of the present invention, the orientation of some minutes faces can remain appreciable with respect to changing over perceived area outstanding and/or that retract for the production of orientation outstanding and/or perceived area that retract, but has rough appearance.So, can produce the effect of glittering.
In order to produce this rough or blaze surface, people can be handled as follows: by depart from arbitrarily intended target orientation in certain limit, the orientation of some minutes faces is changed.Especially, some vicinities divide face also can from target bearing, depart from respectively identical any irrelevance.According to any bias, there is identical minute face amount or the quantity departing from respectively, so can for example produce rough appearance or blaze surface, there is the surface of the effect of glittering.There is this rough surface and maybe can be perceived as the surperficial optically variable element glittering and there is very high identification value, and there is thus very high anti-forgery.
And a minute face can be configured to colour killing difference face.This reflex behavior that especially should be understood to minute face causes because of ray optics effect, or at least by ray optics effect control.Within described minute, face is not thus as diffraction structure or only seldom as diffraction structure.
In optically variable element, the maximum depth of indentation of the intaglio printing in first region can equal at least 20 μ m, preferably equals at least 40 μ m, particularly preferably equals at least 70 μ m.This depth of indentation very well sense of touch detects.
And in optically variable element, the maximum height difference of the relief structure in second portion region (relief structure) can be less than 15 μ m, is preferably less than 10 μ m, is particularly preferably less than 5 μ m.This maximum height difference is so low, makes it can not by sense of touch, be detected or only be difficult to be detected (being generally so destructuring roughness) by sense of touch.
In optically variable element, second portion region can present optic difference in height, and the in esse structure height in second portion region is at least 1/3 of the height that looks on its optics, and preferably 1/5, particularly preferably 1/10.Therefore guarantee second portion region can optics perception and the marking that can sense of touch detects can not mate.
Especially, can be configured to that second portion region feels be smooth to optically variable element.
In optically variable element, first region can especially be made by blind blocking.And first region can be formed on the bottom surface that looks like metal by blind blocking, this bottom surface be color offset and/or flash of light.
In optically variable element, first region can be reflected.
Optically variable element can be configured to two subregions and present identical relief printing plate and represent (relief represention), pattern, continuous pattern and/or the combination pattern relevant with implication.For example, first region can present the palpable bow of sense of touch, and second portion region can present and looks and protrude but not tactile lyra (violin) in sense of touch.Two subregions also can present the pattern such as lyra together, and only a part for the subregional pattern of First can detect with marking sense of touch adaptably that can optics perception.
And for example, first region can be stamped on second portion region at least in part by intaglio printing.So, sabotaging (impression loss) can for example expect in second portion region, makes first region optically be physically located in the place ahead, second portion region, for example, be not translucent.
In optically variable element, second portion region can have micro-structural, and surperficial reflection and/or refraction behavior are protruded in described micro-structural simulation.Described micro-structural can be at least one element in following group: fresnel structure, reflection sawtooth grating or minute face, for example, for protruding diffraction element (Activities Design (animat)), More's amplifier and the A-D converter of simulation, especially have metallized micro-structural.Activities Design is interpreted as especially to refer at this and has the outward appearance that depends on viewing angle, when viewing angle changes, produces visible mobile effect.For example in WO 2007/107235A1, this example has been described.
Micro-structural can be stamped in impression paint.Especially, in micro-structural, also can there is reflection or reflection enhancement coating, especially metallized color offset coating (color of institute's perception depends on viewing angle), high refractive index coating and/or comprise the coating of the ink with reflective paint printing forme, make pigment printing forme be roughly parallel to small relief printing plate and aim at.
Second portion region can be configured to transparent.For example, and it can have part transmission coating (grid or very thin metal) and/or have color offset coating under looking squarely and/or having an X-rayed.Also can provide the metallization pattern that is positioned at side, de-metallization region.
Especially, optically variable element can be configured to be applied to safety line, tear line, tamper-proof strip, false proof, colour code or the mark of cheque paper, value document etc.Especially, optically variable element can be crossed over transparent or at least translucent region or recess.
Especially, term cheque paper is interpreted as the precursor portions that refers to value document, but should not circulate, and except optically variable element of the present invention, value document also can for example have other authentication feature, such as the luminescent substance being arranged in volume.On the one hand, value document is understood as at this file of being manufactured by cheque paper.On the other hand, value document can also be other file and the object with optically variable element of the present invention, to make value document have not reproducible authentication feature, thereby can check that authenticity prevents less desirable copying simultaneously.

The specific embodiment
In the embodiment shown in fig. 1, optically variable element 1 of the present invention is applied to the front side of banknote shown in Fig. 12, and serves as Security element or anti-counterfeiting characteristic, thereby can check the authenticity of banknote 2.
Optically variable element or Security element 1 are configured with the reflection Security element 1 of rectangle exterior contour, and have pattern 3 (in this case monogram AB), and pattern 3 has first region 4 (A) and second portion region 5 (B).
From Fig. 2, be clear that, wherein schematically illustrated Security element 1 is along the cross section of transversal D-D, and Security element 1 comprises substrate 6, and substrate 6 has the reflecting layer 7 that is arranged in first region 4.The upside that deviates from substrate 6 in reflecting layer 7 impresses by gravure process, and has surface texture thus.
Surface texture in first region 4 is chosen to alphabetical A at this and can is perceived as outstanding with respect to substrate 6 by optics.Protuberance 8 height or depth of indentation d1 and lateral dimension are chosen to make the marking matching optics marking can sense of touch detecting.When with finger friction first region 4, people can notice the alphabetical A of rising thus.
The maximum height d1 of protuberance 8 can for example equal 80 μ m, and the progress of height is preferably continuous.In this case, present particularly preferred sense of touch.
Layer 7 not only can be configured to metal level, also can be configured to the layer of metalloid, it applies by printing technology (for example, by serigraphy, aniline printing, letterpress indirectly, hectographic printing or ink-jet), make after intaglio printing, first region 4 can be perceived as the relief printing plate of similar coin sample metal on optics.
Except thering is the ink of simple metal pigment, also alternately use optically variable ink.Also can make different ink combinations with one another, make the first region 4 for example impressing look it is colored.
In second portion region 5, in enamelled coating 11, can construct a plurality of reflections that are for example arranged in substrate 6 and divide face 12.A reflection minute face 12 is arranged and is orientated to them and imitates reflector space 13 for beholder, and it looks and protrudes with respect to the actual macrospace shape of enamelled coating 11 or substrate 6.In described embodiment, reflector space 13 is letter bs, and reflector space 13 is illustrated by the broken lines in the sectional view of Fig. 2.
Imitate the optical effect of reflector space 13 by realizing like this, the inclination of minute face 12 is selected according to their lateral attitude, makes incident light can divide reflection on face 12 by catoptrical equidirectional with raised zones 13.Therefore, incident beam 15 is being parallel to reflection in the direction 16 of direction 16 ', and this direction 16 ' is corresponding to the direction of reflection on surface 13.Same case is applicable to along the light beam 17 and 19 of direction 18 and 20 reflections.These directions 18 and 20 are parallel to direction 18 ' and 20 ', and direction 18 ' and 20 ' is the reflection direction of reflex time on surface 13.
The maximum height d2 of minute face 12 and full-size are preferably chosen to observer can not differentiate a minute face 12 by bore hole.Preferred embodiment shown in Fig. 2 has minute face 12 with substantially constant cycle periodic arrangement.A minute face 12 of this embodiment also has the height along cross directional variations.
Beholder draws thus from the reflex behavior in second portion region 5, in second portion region 5, raised zones 13 has height d3, and this height d3 is obviously greater than the maximum height d2 of minute face 12, and approximately corresponding to the height d1 that is arranged in the protuberance 8 in first region 4.
Therefore, for example, the in the situation that of light beam 15, reflex behavior indicates local surfaces normal pointing direction 21, and these are obviously different from the macro surface normal (arrow 22) of enamelled coating 11.In second portion region 5, therefore by the orienting reflex simulation on minute face 12, protrude, thereby only indirectly obtain the degree of depth marking or the 3D marking.This marking also can be appointed as "
" size Expressing or relief printing plate represent.
Due to the independent small size of minute face 12, the marking can sense of touch detecting in second portion region 5 is obviously different from the marking that can optics perception.Therefore, due to the optics marking, the region that beholder's expectation is protruded forward.Yet when touching second portion region 5, he can touch or notice only general plane region.
Therefore, although in first region 4, but the marking of optics perception coupling tactilely-perceptible, but in second portion region 5, the marking that can optics perception departs from the marking can sense of touch detecting.Therefore, advantageously, for the user without extra servicing unit, can be simply and check uniquely Security element 1 of the present invention.
Divide the maximum height d2 of face can be less than 15 μ m.Preferably, it is less than 10 μ m, and especially, it is less than 5 μ m.
As original minute face 12 of photoresist can be in for example radiation curing paint and/or thermoplastic paint 11 for example by the known gray scale photolithographic exposure of prior art, electroforming, impression subsequently.
In order to strengthen the reflectance of minute face 12, strengthen coating can to minute face cremasteric reflex.They can be for example with metal, to process.
Dividing the coating on face 12 can also be at least color offset in certain area, for example, utilize reflector/dielectric/absorber membrane system to realize by applying suitable liquid crystal or vapour coating.
The sectional view of alternate embodiment shown in Figure 3, wherein, a minute face 12 is made transparent at least partly, and is arranged in the window area 25 of for example substrate 6, and substrate 6 can be the substrate of banknote.
In perspective view, the effect of minute face 12 is, for example refraction in direction 16 of incident light 15, in this direction 16, also can make incident light 15 ' refraction corresponding to curve 26 the protrusion object with identical refractive index.Therefore, second portion region 5 is similar to lenticular object, and it has the surperficial relief printing plate according to curve 26.
In this embodiment, similarly, according to the present invention, the relief printing plate in first region 4 is obviously palpable.Yet, in second portion region 5, as lentiform relief printing plate, become thin foil, wherein, the visible protrusion of vision can not contact.
Except the structure of transparent minute face 12, in window area 25, also can as the first embodiment, use reflection minute face.Preferably, can de-metallization around the region of minute face 12.
For example, and a minute face 12 also can have semitransparent coating (grid or very thin metal especially also have the color offset coating of part transmission).
Certainly, except above-mentioned minute face 12, also can adopt and protrude arbitrarily model configuration, wherein, the marking that can optics perception and the marking can sense of touch detecting do not mate.Therefore, can adopt for example fresnel structure, diffraction structure and More's amplifier or A-D converter, especially there is metallized micro-structural.
Corresponding construction can be stamped, but by intaglio printing, does not impress.Preferably, radiation curing or thermoplastic paint 11 are stamped.Paint 11 can be applied directly to substrate 6.Paint 11 also can be applied on paillon foil, and paillon foil is also attached in substrate 6 subsequently.Or paint 11 can be present on transfer foil, structure is transferred to substrate 6 from transfer foil in a known way.Substrate 6 can also directly be impressed.
And the micro-structural in second portion region 5 can be arranged in multi-ply construction.Therefore described micro-structural can for example be positioned at the inner side of outer paper tinsel, and avoids better thus external action.For example, the micro-structural that forms second portion region 5 can be configured between two outer paper tinsels of polymer banknote or between the ply of paper and paper tinsel layer of mixing banknote.Especially, the whole carrier core of substrate 6 can comprise the micro-structural that forms second portion region 5, and described micro-structural is by covering paillon foil protection.
In the embodiment describing so far, two subregions 4,5 (in this case alphabetical A and B) are spaced apart.In Fig. 4, another example of the layout of two subregions 4,5 is shown.At this, the impression relief printing plate in first region 4 (the in this case form of alphabetical A) by only have the second portion region 5 of protruding outward appearance around, subregion 5 has the form of convex hole, this convex hole has the letter b that for example protrudes outward appearance.
In the embodiment shown in fig. 5, the actual pattern A (first region 4) protruding is positioned at the place ahead of the background with a plurality of letter bs only with protrusion outward appearance (second portion region 5).Pattern B can be the lake scape (being formed by little minute face under the microscope) of for example relief printing plate outward appearance at this, and pattern A can be ship for example, and it is stamped on second portion region (letter b) by intaglio printing.At this, there is sabotaging in second portion region 5 (impression loss).Therefore, ship can for example be positioned at waterborne, and it is translucent not seem.
In the embodiment shown in fig. 6, two subregions 4,5 directly meet boundary each other.
