Definitions
- the invention relates to data carriers, in particular securities, documents, identity cards or the like.
- an optically variable security element that contains a liquid crystal material. Because of the easier legibility, the abbreviation FK for liquid crystal is often used in the following.
- optically variable elements as security elements is increasingly being propagated for data carriers.
- Such elements have in common that they have different color or brightness renditions depending on the lighting and viewing conditions.
- the most common optically variable elements include diffraction gratings, holograms, interference coatings, metameric colors and polarizing coatings.
- a card is already known from WO-A-82/02445 which contains optically recognizable markings, these markings in turn being covered with a liquid-crystalline element.
- the liquid-crystalline layer In the normal state, the liquid-crystalline layer is opaque, so that the marking underneath cannot be seen.
- the liquid-crystalline layer can be brought into a transparent state, so that the marking for test purposes can then be recognized.
- Interference coatings usually consist of several superimposed layers, the layer thicknesses being the size of the wavelength of the light.
- Metameric printing inks usually consist of mixtures of pigments with different reflectance bands. This composition causes the metameric colors to change their visual color impression when the type of lighting is changed.
- Dichroic dyes have the property of absorbing white light in different wavelength ranges depending on the direction of polarization. The result is a polarization-dependent color impression.
- a disadvantage of the known optically variable authenticity features is that they are either very expensive to manufacture, cannot be processed with conventional manufacturing processes, or are only compatible to a limited extent with other authenticity features or card elements.
- the object of the invention is to propose a feature which is effective as copy protection and which has viewing angle-dependent effects, which can be produced inexpensively and by conventional methods and is compatible or combinable with other features.
- the invention is based on the use of liquid crystal polymers as security elements. After suitable oriented production at room temperature, these polymers represent a plastic-like solid with a pronounced interplay of colors. Such a suitable production process consists, for example, of knife coating the still liquid material onto a base and then curing it by means of UV radiation. Liquid crystal polymers and cholesteric organopolysiloxanes are particularly suitable as liquid crystal polymers. Suitable liquid crystal polymers, their chemical structure and their preparation are described in the published patent applications EP-OS 0 136 501, EP-OS 0 060 335 and EP-PS 0 066 137. Reference is expressly made to the disclosure content of these publications.
- liquid crystals In spite of structural anisotropy, liquid crystals usually behave like a liquid, which is why it is necessary to enclose these materials in capsules or cavities. This results in a complicated manufacturing technique. In addition to the complex encapsulation of the LC materials, it is not possible due to the risk of injury to the cavities or capsules to embed the proposed security elements in the conventional manner under pressure and heat (classic laminating technology) in foils or identity papers. Encapsulated liquid crystals are also unsuitable as security elements on banknotes or securities with steel gravure printing, since the high pressure loads required in this manufacturing process lead to the destruction of the capsules and cavities.
- liquid crystals can also be in solid form after appropriate processing and, depending on the processing method, have a high-grade alignment of their molecules, as a result of which the optically variable properties emerge in full and in full brilliance.
- the color purity of the reflected light rarely exceeds a range of 100 nm, the color change effects with the change in the viewing angle are very pronounced, and the reflected and transmitted light has a pronounced circular polarization.
- the fully developed optically variable properties make such LC polymers particularly suitable for use as security elements on data carriers, securities and ID cards.
- the color changing games are easy to observe even for laypeople.
- the wavelength-selective reflectivity and the polarization effects make the material highly suitable for automated testing.
- the FK elements can also be used both as machine-readable authenticity features and together with other machine features. Due to the IR permeability of the LC polymers, the other machine features can also be arranged under the LC polymers under certain circumstances.
- the solid-state properties of the FK polymers make it considerably easier to manufacture security elements from them. Firstly, there is no need to enclose the liquid crystals in a hollow body, secondly there is no risk of the liquid crystals bursting open and escaping during subsequent processing steps and during the life of the data carrier. The manufacturing processes and the application are extremely easy.
- the plastic-like properties of the liquid crystal polymers enable easy processing into semi-finished or finished products.
- the starting material is generally in the form of granules and can be shaped and processed further using the methods and machines known from plastics production. This makes it possible in the field of security technology to manufacture completely different types of security elements on the basis of LC polymers and to cover different applications.
- Carrier webs made of a tear-resistant plastic can be coated with a layer of LC polymers. The resulting material web can then be cut into narrow webs or threads that can be embedded as security threads in paper or other materials.
- multilayer film webs can also be produced which contain an embedded layer made of an LC polymer.
- Such webs can be designed as adhesive tapes or transfer tapes, which are suitable for gluing or stamping transfer elements on paper or plastic surfaces.
- LC polymers can also be produced as self-supporting films.
- These foils can be used, for example, as foil layers for multi-layer ID cards.
- LC polymers are a special variant of liquid crystals in which the liquid crystalline state is "frozen" in a polymer matrix, which makes the optical properties particularly significant.
- liquid crystal polymers do not normally absorb light, and their color is created by multiple interference of light at the individual crystal planes. The color impression in reflected and transmitted light is accordingly different.
- the reflected color spectrum contains only a narrow frequency range around a central wavelength and therefore shows a high color saturation.
- the transmitted spectrum is complementary to the reflected spectrum and has a dip in the region around the central wavelength.
- the lattice constants of oriented LC polymers according to the invention can be set in the range from 300 nm to 1000 nm or defined in the synthesis, so that the reflected central wavelength is in the near infrared or in the visible in the case of perpendicular incidence. As the observation angle becomes flatter, the central wavelength of the reflection band shifts in the direction of shorter wavelengths. For example, the wavelength reflected in the top view is about 20% larger than the reflection at 60.
- the color impression can accordingly for special LC polymers from green to violet, from yellow to blue, from light red to green or change from black to red for an IR reflection band.
- the lattice constant and thus the basic color of the liquid crystal polymer depend on the exact chemical structure of the liquid crystal and can be set in a defined manner in the range between 300 and 1000 nm by the synthesis conditions.
- Fig. 2 shows an application of an FK polymer for a window security thread.
- a security thread 13 has been embedded in a banknote 11 with a security print image 12 during the paper production in such a way that it comes to rest on the surface of the paper in the windows 14 and is thus visually recognizable.
- the width of such security threads fluctuates between 0.5 and a few millimeters.
- the security thread 13 is formed in such a way that it contains one or more layers made of an LC polymer. Variants for the production and for the construction of security threads are shown in FIGS. 3-7.
- a security thread 13a shows in cross section a first variant for a security thread 13a; it consists of a plastic carrier 20, preferably a polyester film with a typical thickness of 20-100 micrometers is used for this.
- the carrier 20 is coated on one side with a several micrometer thick layer 21 made of an FK polymer.
- the film 20 is preferably colored black.
- the thread is oriented during papermaking so that the liquid crystal layer is on the visible outer surface.
- the thread 13b shows in cross section as a further variant a security thread 13b with a symmetrical layer structure.
- Symmetrically constructed security threads have the advantage that one does not have to pay attention to the orientation of the thread during embedding in the paper.
- the thread 13b consists of two carrier foils 20, both of which are coated on one side from a layer 21 made of LC polymers.
- the carrier films 20 are connected to one another by a laminating agent 22 in such a way that a symmetrical layer structure with external LC layers is produced.
- a laminating agent 22 In order to increase the color richness, one can optionally color the carrier webs 20 and / or the lamination mediator 22 with transparent or pigment colors.
- a solution that is simple in terms of production technology is to color only the lamination mediator 22, preferably an opaque black is used for this.
- FIG. 5 shows a further variant of a symmetrically constructed security thread 13c in cross section.
- the carrier films 20 now lie on the outer sides of the thread 13c and thus protect the internal LC layers 21 from damage.
- the lamination mediator is colored with a dye. Since the outer carrier layers 20 must remain transparent, they are either not colored at all or only weakly.
- FIG. 6a and 6b show a further variant of a security thread 13d in cross section (FIG. 6a) and in supervision (FIG. 6b).
- the thread 13d has analogous to FIG. 5, a symmetrical layer structure consisting of two carrier foils 20, two LC layers 21 and an adhesive layer 22.
- the thread was assembled from two coated foil pairs 30, 31.
- the surface 33 of one of the two pairs of foils was provided with a printed image 34 made of black color, and alphanumeric characters were applied to the surface of an LC polymer layer in a conventional printing process in micro script.
- a transparent laminating agent 22 was used. In transmitted light, the characters now appear black in the window areas of the paper against the optically variable color background of the polymer layer. In contrast, only the micro characters show a color change in reflected light.
- the characters 34 are applied in green microprint on one of the LC layers, while the lamination agent 22 is colored black.
- the LC material is selected so that it appears green under a certain viewing angle, for example under vertical incidence on the black background. When observing the security thread at this angle, the entire area appears green. When the viewing angle changes, the color of the FK polymer layer changes, while in the font the green color remains dominant. The result is a security thread, the writing of which only becomes visible when the thread is tilted.
- the security thread consists of a carrier film 20 and a layer 21 made of LC polymers.
- the polymer layer was printed in a conventional printing process with a pattern of differently colored, diagonally extending strips 40. In the example shown, red 41, yellow 42, green 43, blue 44 was selected as a special color sequence for the pattern 40, the pattern being repeated any number of times over the thread length.
- the colored surface areas 40 each appear with different color effects through the LC layer.
- the color spectrum of the individual areas is made up of the reflection band of the printed dyes.
- the colors of the liquid crystal layer are mixed in additively.
- this embodiment variant can also be expanded to form a security thread with a symmetrical layer structure.
- the variants shown in FIGS. 3-7 can be varied in a variety of ways depending on the desired appearance.
- the optically variable effects of the FK polymers can be combined by coloring any layers with "classic" colors, whereby both transparent dyes and pigment dyes can be used as dyes.
- the dyes themselves can be incorporated in any layer (also in the LC layer, but then only in low concentrations) of the security thread and / or can be applied as a printed image on any layer of the thread.
- the variants of security threads shown in FIGS. 3-7 can be produced on the basis of a single semi-finished product.
- a film web 20 made of a carrier material such as polyester plastic is coated with a layer 21 made of LC polymers.
- LC polymers Depending on the color design of the security thread, printed, transparent or colored carrier foils are used.
- the thickness of the film web is preferably in the range of less than a tenth of a millimeter, and a film thickness of approximately 10 micrometers is usually sufficient for the LC coating. Due to the manufacturing process, the typical web widths of the semi-finished product are in the range of one meter.
- the carrier web and / or the LC layer are printed with the desired patterns or characters on known printing machines in a suitable manufacturing process.
- the coated and possibly printed film webs are placed on top of one another and connected with a laminating agent.
- the final thread width is between 0.5 and 5.0 mm, depending on the intended use.
- the threads thus obtained are particularly suitable for embedding in paper, but can also be embedded between the plastic layers of an identification card.
- Another class of security elements are the transfer elements, they are often open Credit cards, ID cards, banknotes, securities and the like applied to protect them against counterfeiting and in particular against duplication by copying.
- Security elements based on LC polymers are also suitable for these purposes due to their optically variable properties.
- the transfer elements are transferred from carrier tapes to the surface of the objects to be protected using the transfer method.
- the 8a and 8b show an identification card 50 with a symbolically indicated data record 49 and with a transfer security element 51 in supervision and as a sectional view.
- the security element 51 contains a layer of an FK polymer, which is why it has the color change interactions typical of these materials.
- FIG. 8b shows a section through the identification card along the line I / I in FIG. 8a.
- the height of the element is shown exaggerated, usually it is only a few 10 microns.
- An adhesive layer 54, a protective lacquer layer 55, an LC layer 56 and a protective lacquer layer 57 that closes off to the outside lie one after the other on the substrate 53.
- This security element which is shown here in a very simple embodiment, can be varied in many ways.
- the options for the color design of the FK elements are analogous to the security threads. If you attach importance to visually clearly recognizable color change games, then you prefer to color the surface black.
- the element 51 was applied to a printed background 60.
- the printed image can be varied in many ways, a simple design is a single-colored background, an improved optical effect has a multicolored printed background with contrasting alphanumeric characters or patterns such as diagonally running colored stripes, nested colored circles, etc. Particularly interesting effects result when the background 60 contains a black and white or color photograph, a signature and the like.
- the transfer principle enables the optical element to be given any external outline.
- the coat of arms shape 61 shown in FIG. 8 therefore represents a stripe, a seal, a company logo, an alphanumeric character, a number, guilloche pattern, etc.
- the shape of the outline 61 gives the optically variable element an individual expression.
- FIG. 9a and 9b show a top view and a sectional view of an application variant in which map data are concealed with an FK element and are concealed at the same time and protected against falsification.
- FK polymers with visually visible color change interactions are mostly transparent in the infrared and can therefore be effortlessly combined with codes that can be read in the infrared range.
- a code 72 was applied to the surface of a card 70 with an IR-absorbing ink 71.
- this IR coding 72 was overprinted with an IR-transparent top color 73, but opaque in the visible spectral range.
- an LC security element 74 was then sealed onto the covering color 73 in this area.
- the transfer principle is preferred for applying security elements made of LC polymer to the surface of a substrate.
- a transfer belt is produced in a first process step, then in a second process step the security element is detached from the transfer belt and connected to the substrate.
- FIG. 10 shows the structure of a transfer belt 100 in cross section as it is suitable for applying security elements with an LC layer to a substrate surface.
- a carrier film 101 On a carrier film 101 there are successively a wax layer 102, a protective lacquer layer 103, a layer made of an FK polymer 104, a color layer 105 and a hot-melt adhesive layer 106.
- the carrier film preferably consists of a tear-resistant plastic (polyester) with a thickness in the range of less than a tenth of a millimeter.
- the remaining layers of a transfer belt usually have a thickness of a few micrometers to a few tens of micrometers.
- the layers 103-106 lying on the wax layer form the later security element.
- the transfer ribbon can be colored or printed in different layers during its manufacture.
- the transfer tape 100 is placed with the hot-melt adhesive layer 106 on the substrate 111 and pressed.
- the pressing takes place with a heated transfer stamp 112 or alternatively also with a transfer roller.
- the hot-melt adhesive layer bonds to the substrate under the influence of pressure and heat.
- the separating layer 102 melts and allows the carrier material 101 to be pulled off.
- the security element is connected to the substrate only in the surface areas in which the separating layer has become liquid, ie only in the surface areas heated by the transfer stamp. In the other surface areas, the layer structure and the carrier material remain firmly connected.
- the layer structure tears along the contour edges 113 of the transfer stamp, as a result of which the contour 113 of the transferred security element always corresponds to the contour of the embossing stamp. In this way, complicated outline structures such as company logos, block letters and the like can be realized.
- the process of heat sealing as such is known and is described for example in DE-OS 33 08 831.
- FK polymers can also be processed into films. In this form, they are particularly suitable as large or full-surface security elements for multi-layer ID cards.
- a laminated identification card 120 which consists of a paper insert 121 and two external thermoplastic cover foils 122 and 123. The layers are pressed into a compact ID card under pressure and heat.
- the card information is usually printed on the ticker, which in the example shown has an image of the holder 124, card data 125 and a company logo 126.
- a film made of FK polymer 127 was inserted into the card structure between the ticking and the top cover film in the left half of the card. The color change interactions of the liquid crystal film can be observed through the transparent cover film, with the colored printed company logo 126 additionally adding color effects.
- Some LC compounds cross-link under the influence of high-energy (e.g. UV) radiation and only then form a chemically stable film.
- Unexposed, i.e. H. Areas that have not hardened can be removed with solvents.
- a defined area of an LC film can be exposed in this way through a mask and the coating can then be removed chemically in the unexposed areas, so that patterns, letters, numbers etc. are produced.
- a further variant consists in replacing one or both cover foils 122, 123 as a whole in the usual construction of laminated cards with an FK foil.
- Films made of Fk materials are suitable as large or full-surface security elements. Such films are preferably made from a liquid crystal substance. In order to obtain a film suitable for security purposes, the LC substance is processed on a roller mill. The alignment of the liquid crystal molecules necessary for the optical effects takes place through shear forces that occur during rolling. The film material produced in this way is particularly suitable for the production of identity cards, but can also be processed to other authenticity indicators, such as a security thread.
- the polarization properties and their wavelength selectivity are particularly suitable for the machine testing of authenticity indicators on the basis of the liquid crystal polymers according to the invention.
- the reflected light is initially narrowed spectrally over a range around the central wavelength, furthermore unpolarized light is broken down into liquid-crystal operators into right and left rotating components. Depending on the chemical composition of the polymer, only one of the two parts is reflected, while the complementary part is transmitted.
- the element 130 is illuminated at a predetermined angle with an unpolarized light beam 131, for example an incandescent lamp 129. After the reflection, the light beam 132 strikes the detector system 133 shown in FIG. 14, with which the detection of the spectral filtering and the circular polarization is carried out.
- the structure of the detector system 133 is shown in FIG. 14.
- the reflected beam 132 first passes through a color filter 141 which only allows light of the expected central wavelength to pass.
- the light beam then strikes a lambda / 4 plate 142, which converts the circular polarization into a linear polarization.
- the light then falls on a 1: 1 beam splitter 143, from where the two partial beams 144, 145 reach two detectors 146, 147 with polarization filters 148, 149 arranged in front of them.
- the polarization planes 150, 151 of the two filters are perpendicular to one another, at the same time they are aligned at 45 ° to the two optical axes of the lambda / 4 plate.
- the machine authenticity check is based on an analysis of the two detector signals.
- the mode of operation of the detector system is shown below in several cases.
- the reflected light passes unhindered Color filter.
- a linear polarization either horizontal or vertical, is generated from the circular in the Lambda / 4 plate.
- the linear polarization means that one of the two detectors 146, 147 receives the full intensity, while the second detector receives no light.
- the spectrally correct, but non-polarized reflected light does not have a preferred polarization direction even after passing through the lambda / 4 plate. Both detectors each receive 50% of the reflected light.
- the reflected light is absorbed in the color filter 142, and accordingly neither of the two detectors receives a signal.
- the 45 ° arrangement of the lambda / 4 plate and the two polaristors means that both detectors receive the same signal regardless of the original polarization direction of the reflected light.
- detector systems can also be used to test a single element; which are arranged at different angles, for example, and react accordingly to different central wavelengths.
- the detector system can be implemented in many ways.
- 15 shows an arrangement using optical fibers as a maintenance-friendly alternative.
- the basis of the optical arrangement is again FIG. 13.
- the reflected light beam 132 first passes through a color filter 161 for checking the central wavelength.
- Lambda / 4 plate 162 the circular polarization is converted into a linear one.
- a coupling optic 153 couples the light beam 132 into a light guide system 154, known beam switches separate the beam into equivalent partial bundles.
- At the end of each sub-bundle there is a pair of polarizer-detectors 155/156 and 157/158 for the two different directions of polarization.
- one of the two detectors 156/158 receives 50% of the input intensity (in the case of lossless optics), the second does not receive any light.
- each of the two detectors receives 50% of the input intensity. In this way, counterfeit and original can be distinguished.
