Definitions

  • the invention relates to security elements for security papers or documents of value, such as banknotes or identity cards.
  • the security elements have at least in transmitted light, possibly also in incident light, visually recognizable characters, patterns or codes as well as additional substances for machine testing.
  • the invention also relates to methods for producing the security elements and security papers and security documents equipped with the security elements.
  • Security elements in the form of threads, tapes or labels used to authenticate banknotes, checks, credit cards, identity cards and the like or used for product marking are known.
  • Such security elements typically consist of a light-permeable, ie translucent carrier material with a metallic coating.
  • the metallic coating contains recesses in the form of letters, numbers, patterns or other signs. The recesses are visually recognizable and are particularly visible when looking at the security element against the light. The recesses then form a bright contrast against the dark appearing metallic coating.
  • a security element for a security document such as a banknote, identity card or the like, which consists of a translucent plastic layer comprising an opaque layer with visible in transmission recesses in the form of characters, patterns or the like and a magnetic layer, which is arranged under the opaque layer , wherein the magnetic layer is in the form of spaced-apart magnetic regions which form an encoding and the recesses are arranged in the magnetic-layer-free intermediate regions of the coding.
  • Machine readable filaments using electrical conductivity and / or magnetism as test criteria are often used for automated banknote processing. These machine-readable properties of the threads are produced by printing suitable colors (functional colors) inside the laminate structure of the threads. The internal structures are well protected from chemical and mechanical stresses by covering films. The imprint of the functional colors, which impart the machine-testable properties, typically takes place in strip form along the thread axis or in the form of blocks perpendicular to the thread axis.
  • a security element for security documents which has both a negative writing and a magnetic security feature.
  • the security element consists of a translucent plastic film as a carrier material with a first metallization layer, to which in turn a layer of magnetic ink and a further metallization layer are applied.
  • the metallization layers are vacuum-deposited metal layers or metallic effect layers, ie layers of metal pigment-containing paint or metalimitation paint.
  • the negative writing is produced by printing the carrier material with an activatable printing ink in the region of the later negative writing before applying the layer structure. Activating the ink will cause the areas of the ink over the ink to become darker Layer structure removed and there are recesses in the form of negative writing.
  • the activatable inks are inks that soften by heat, thereby reducing adhesion to the substrate, or inks that contain intumescent additives that release gas when heated, thereby also reducing adhesion to the substrate and the overlying layers be arched.
  • the disadvantage is that the simultaneous removal of several layers leads to recesses whose contours are not as sharp as would be desirable, which is not tolerable, especially with small characters.
  • the first metallization layer and the magnetic pigment-containing printing ink are applied only to partial regions of the carrier material.
  • the negative writing is printed with an activatable ink and then applied over the entire surface of the other metallization.
  • a security element which consists of an at least translucent plastic layer having an opaque layer with recesses, which form a negative font, and a machine-readable magnetic coding, wherein the recesses are arranged in the retegnet harshelle areas of the security element.
  • the magnetic coding is covered by another opaque layer so that it is invisible to a viewer.
  • the opaque layers are metallization layers, ie vapor deposited metallic layers or layers printed with metallic pigment containing colors.
  • the recesses of the negative writing and the magnetic regions may be geometrically arranged on the security element in different ways.
  • the negative writing in the metallic coating is produced by printing a soluble ink layer in the form of negative writing to be formed on the support plastic layer, then vapor-depositing the metal and then dissolving the soluble ink with a solvent, the ink together with the ink thereon evaporated metal is removed.
  • the machine-readable security features are generated by means of so-called function colors.
  • the functional colors contain metallic pigments, such as. As iron oxides, for the award of magnetic properties (magnetic paint), or electrically conductive particles, such as. Conductive carbon black, for imparting electrical conductivity (conductive ink), or both metallic pigments and conductive particles when magnetic properties in combination with electrical properties are desired.
  • the functional colors are therefore usually physically black or brown and roughly structured. Since the machine-readable layers should not disturb the optics of the security element and the machine readability of a security element should not be apparent to the unaided eye, the layers are covered, usually by means of metallization layers, as disclosed in the aforementioned publications. The visual appearance in terms of color and texture of the surfaces should be as far as possible identical on both sides of the security element, d. h., the security element should not be "two-sided".
  • the functional colors with metallic and / or conductive pigments Due to the composition of the functional colors with metallic and / or conductive pigments, it can in direct contact with a metallic Layer, for example, a vapor-deposited aluminum layer, as is often used for security elements, in the presence of moisture to the formation of a galvanic element and thus come to corrosion. Traces of moisture are sufficient. The presence of moisture can be found in security papers and documents of value such. B. banknotes, can not be excluded. For example, they are used in humid climates or may accidentally be washed with a garment. Also in the manufacturing process, especially in the generation of negative writing, the security elements can come into contact with moisture, as will be explained later.
  • a metallic Layer for example, a vapor-deposited aluminum layer, as is often used for security elements, in the presence of moisture to the formation of a galvanic element and thus come to corrosion. Traces of moisture are sufficient. The presence of moisture can be found in security papers and documents of value such. B. banknotes, can not be excluded. For example,
  • plastic carrier film metallic effect layer
  • machine-testable layer metallic effect layer
  • metallic layer metallic layer
  • the metallic effect layer between the machine-testable layer and the metallic layer prevents with good reliability the formation of a galvanic element and thus a corrosion of the security element, but also has a number of disadvantages.
  • the pressure of the metallic pigments is relatively expensive.
  • the paint does not print well because of the high level of metal particles that give the metallic sheen, and if the viscosity is too low, the paint tends to splash.
  • the poor processability leads to great problems in controlling the printing, because the cover must be printed in the register on the magnetic pressure, which in turn leads to increased waste.
  • the squeegees must be changed frequently during production, since the metal pigment-containing colors are highly abrasive, so that production often comes to a standstill.
  • the drying of the layer sequence of metal effect layer, machine testable layer, metal effect layer is extremely difficult, which is due to the high porosity of the layers, which allows a displacement of the solvent from one layer to another.
  • the solvent appears to strike away from the metallic effect layer in the machine coat of functional ink.
  • the stripped solvents may "boil" during later drying operations and form bubbles in the layers.
  • the high residual solvent levels lead to problems in the metallization, because no good vacuum can be achieved, during lamination, because unwanted reactions can occur with the laminating lacquer, and when cutting the security elements to the desired dimensions, since magnetic abrasion can occur.
  • the security element shows a clearly two-sided appearance.
  • the reason is that the pressure of a metal effect layer on a smooth plastic carrier film gives a relatively smooth glossy image, while the printing of a metallic effect layer with the same composition on the machine testable layer does not give a smooth, but a rather coarse textured image.
  • the functional colors magnetic coatings, conductive inks
  • the metal pigment-containing paints or imitation paints for forming the metallic effect layer are relatively expensive, and their use also entails high tooling costs because of their high abrasiveness. Gravure cylinder and squeegee must be changed frequently.
  • the object of the present invention is therefore to provide a security element for a security paper or a document of value, which has a metallic coating with recesses recognizable at least in transmitted light as well as a machine-testable layer with at least one machine-testable feature, in which corrosion problems are avoided and those mentioned above Disadvantages eliminated or at least reduced.
  • a security element with the above-mentioned layer sequence, plastic carrier film, Metal effect layer, machine-testable layer of functional ink, metallic layer with recesses in function-color-free areas, between the machine-testable layer and the metallic layer, a paint layer applied.
  • the security element can be created as follows:
  • a translucent, transparent or at least translucent carrier film which is as transparent as possible for example a polyester film, preferably a PET film, is coated with a metallic effect composition, i. H. a metal pigment-containing paint or a Metallimitations shall, printed, wherein at least the portions of the film, which are to have the recesses later, must remain free (open areas of the metallic effect layer).
  • a mechanically testable layer in particular a composition with at least one machine-testable substance, eg. As magnetic paint and / or conductive ink, printed, the printed area must not be greater than the area printed with the metallic effect composition surface, so that the machine-testable layer, viewed from the opposite side, is not visible.
  • a lacquer layer is printed.
  • a colorless paint can be printed over the entire surface, a dyed paint must be printed so that it remains invisible when the security element is viewed from the opposite side.
  • a removable ink in the form of characters, patterns or codes is printed on the free areas of the carrier film or optionally on the printed only with the paint layer areas of the carrier film.
  • the order of the printing processes is not essential. It can also be printed first, the removable ink and then the remaining layers, but where possible the removable ink not from the Protective lacquer layer should be overprinted.
  • Suitable peelable inks and methods of detachment are, for example, in EP 0 330 733 , in the WO 92/11142 and in the WO 99/13157 which is incorporated herein by reference. Particularly preferred is in the WO 99/13157 revealed soluble color.
  • the paint has a high pigment content and, after drying on the printing substrate, forms a raised application of paint having a porous structure with a large surface area. Subsequently, a metallic coating, for example made of aluminum, iron, cobalt or nickel, applied over the entire surface, preferably by evaporation in vacuo. The machine-testable layer is no longer visible, no matter from which side the security element is viewed. In the areas of the recesses, the removable printing ink with the metallic coating overlying it is then removed again. With regard to appropriate procedures, reference is made to EP 0 330 733 , the WO 92/11142 and the WO 99/13157 directed.
  • the security element preferably further protective and / or the application to or the introduction into a paper facilitating layers are applied. Suitable layers are associated with Figure 11 described. Finally, the finished layer structure can then be cut to the desired dimensions of the security element.
  • the metallic coating does not form a coherent metal layer due to the highly porous surface of the paint application.
  • the Demetallmaschine in the field of printed characters, patterns or codes is particularly easy by means of a washing process possible.
  • the washing liquid may be the discontinuous coating easily penetrate. It is therefore easy to wash off the ink together with the discontinuous metal layer.
  • the action of the washing liquid can be assisted by mechanical means such as brushing, rolling, or ultrasound.
  • the releasable ink contains water-soluble binders, so that water can be used as a washing liquid.
  • the carrier film For demetallizing, ie for removing the printing ink together with the applied on the ink areas of the metal layer, the carrier film is completely immersed in water. After demetallization is carefully dried. Nevertheless, traces of residual water can remain, which act as an electrolyte and cause corrosion. Also, by later migrating moisture over the cut edges of the security element in the layer structure inside corrosion can be caused.
  • the lacquer layer between the machine-testable layer and the metal layer reliably prevents such corrosion phenomena. In addition, it has a number of other advantages over the metallic effect layer used hitherto.
  • the lacquers In contrast to the metallic effect compositions, the lacquers contain no solid particles and are therefore easy to print. Difficulties in controlling a register-containing pressure do not occur or only to a small extent and the rejects are noticeably reduced. In addition, the service life of cylinders and squeegees are very high.
  • a paint For a paint, other solvents may be used than for a metallic effect composition, for example, ethanol instead of ethyl acetate.
  • ethanol instead of ethyl acetate.
  • the drying of the paint is thereby much easier, since a displacement of the solvent are avoided in another layer can. Also resulting from the difficult drying resulting problems are avoided.
  • the smoother surface achieved by coating with paint has even more advantages.
  • the risk of breakage of the vapor-deposited metallic coating under mechanical stress, for example when demetallizing, is reduced.
  • the electrical conductivity of the security element is thus better protected against circulation conditions.
  • the smoother surface of the covered machine-testable layer also simplifies the demetallization in the washing process.
  • Another advantage is the low cost of a paint compared to a metal pigment-containing ink or a Metallimitations unit.
  • the reduced tool costs due to the lack of abrasion of a protective varnish also make a book.
  • the paint protects the layer structure against chemical attack.
  • a suitable chemically resistant lacquer must be chosen.
  • suitable lacquers are chemically resistant and transparent nitrocellulose-based lacquers, polyamide, PVC-based or else crosslinking, transparent lacquers, for example isocyanate-crosslinking polyurethanes.
  • the embodiment described above also has some disadvantages that it has in common with the prior art and that inter alia related to the fact that the metallic layer in which the recesses are formed as the last layer of the layer sequence metallic effect layer, machine testable layer, metallic layer, is applied.
  • the metallic effect layer and the machine-testable layer build up relatively strongly. For winding technical reasons, therefore, the roll length is limited before the application of the metallic layer. In addition, only relatively short webs can be printed because of the high abrasiveness of the magnetic paint / conductive ink. The vacuum deposition of the metallic layer therefore takes place on rollers of relatively small length, so that relative to the roll length of the produced at startup and stop Committee is correspondingly high.
  • the surface to which the metallic layer is vapor-deposited is relatively uneven, because the metallic effect layer and the machine-testable layer deposited thereon form raised areas with deeper areas therebetween.
  • the metallic layer covers elevations and depressions alike.
  • demetallization between the functional-color blocks may become difficult. It can lead to unclean washout and imprecise recesses. Unwanted washouts during demetallization can also be caused by a so-called toning of the binder, which occurs again and again when printing magnetic paint / conductive ink.
  • toning here refers to the phenomenon that when gravure on the surface of the gravure cylinder, a more or less thin binder film remains, which can lead to doctor blade in the printed image.
  • the uneven surface can also lead to the fact that in certain geometrical arrangements of the machine-testable layer, for example in the form of functional color blocks, such as magnetic paint blocks, the thin, vapor-deposited metal layer is mechanically stressed during demetallization so that it breaks, and the previously given conductivity is interrupted. For security elements with required conductivity, it is therefore necessary to additionally provide a printed conductive ink layer.
  • the security element according to the second aspect of the invention has the following layer sequence: transparent or at least translucent plastic film, metallic layer with recesses in the form of characters, patterns or codes in functional color-free areas, protective lacquer layer or primer or primer layer, machine-testable layer of functional ink (eg Magnetic lacquer / Leitlack), Metalltechnischs harsh, ie for the Viewer metallic appearing layer.
  • the layer that appears metallic to the viewer is expediently provided by a metallic effect layer or a metallic layer.
  • a releasable printing ink in the form of the recesses to be formed, ie with the desired demetallizing motif, is printed on a transparent or at least translucent carrier film.
  • the printed carrier film is provided with a metallic layer, for example of aluminum or another metal; Preferably, the metal is evaporated in vacuo.
  • the carrier film is demetallized, ie in the areas printed with the ink, the releasable ink is removed together with the metal deposited thereon.
  • the demetallization process depends on the removable printing ink used. It may optionally be mechanically supported.
  • a transparent or at least translucent adhesive layer or protective lacquer layer is now printed over the entire surface.
  • the primer layer protects against the formation of a galvanic element between the metallic layer and the subsequent machine-testable layer. Depending on the type of paint, it can also improve the adhesive properties between the metallic layer and the machine-testable layer (adhesion promoter) and / or increase the chemical and / or mechanical resistance of the security element compound.
  • suitable lacquers are lacquers based on nitrocellulose, PVC-based, polyamide-based or crosslinking lacquers, in particular isocyanate-crosslinking polyurethanes.
  • the machine testable layer z. B. of magnetic paint and / or conductive ink, printed on and followed by a seemingly metallic layer, for. B. a layer of metallic effect paint, such as a metal pigment-containing printing ink.

  • This embodiment has the advantages of the first-mentioned embodiment as well as additional advantages.
  • the mechanical stress during demetallization is low, whereby the risk of interruption of the electrical conductivity is substantially reduced.
  • the pressure of (additional) Leitlackspuren can therefore be omitted.
  • the flat surface also allows a more precise, contour-sharp demetallization without dirty washouts. Since the demetallization takes place prior to printing the function color, any toning of the function colors also has no influence on the demetallization.
  • the inner layers are optically laminated very well.
  • the appearance of this side of the security element corresponds to a security element which has only one metallic layer with recesses.
  • the security element is applied to a security paper in the correct direction, the further layers and in particular the machine-testable layer can not be recognized. If the security element is not to be visible on the back of the paper, the security element on its back side can be additionally printed with an opaque white layer. This opaque white print can also be used at the same time for online checking of the page-correct insertion on the paper machine.
  • a second transparent or at least translucent protective lacquer layer can be provided over the entire surface between the layer of metallic effect ink and the machine-testable layer. Preferably, this layer is printed.
  • the second layer of protective lacquer provides the additional advantage that the rough, granular surface of the machine-testable layer is leveled, and on the smoother surface of the machine-testable layer, the metallic effect color results in a more optically homogeneous printed image.
  • the optical two-sidedness of the security element is therefore reduced.
  • a second metallic layer can also be used as the layer appearing to be metallic.
  • the second metallic layer is preferably substantially only in the areas in which the machine testable Layer is provided, provided so that the recesses remain well visible in the applied to the carrier film, the first metallic layer.
  • a second protective lacquer layer is printed over the entire area between these layers. In order not to hinder the visibility of the recesses, the second layer of protective lacquer must be transparent or at least translucent.
  • the second protective lacquer layer is printed over the whole area and then printed on the areas which are not to be covered with a metallic layer later on, a removable printing ink. At least the area of the recesses in the first metallic layer is to be printed with the removable printing ink. Thereafter, the second metallic layer is evaporated and then demetallized with a suitable demetallization process, depending on the used Ablösbarer printing ink in the releasable ink printed areas.
  • the cover by the second metallic layer has the advantage that it greatly reduces the visibility of the magnetic paint or Leitlack blocks, since the optical properties are dictated by the metal layer. It remains only the visibility by a certain roughness of the covered layers, especially in the magnetic paint printing, which is already well balanced by the protective coating. It can be even further reduced by additionally printing the machine-testable layer with metallic effect ink and providing the second protective lacquer layer on the layer of metallic effect ink.
