Definitions

the invention relates to a security substrate for documents of value, such as banknotes, cheques, credit or other payment cards, identity cards or the like, which has a front and a back and covers a specific area in plan view, is film-based and has at least one relief structure.
Banknotes with different substrates currently exist. Paper, polymer and mixed forms of paper and polymer in the form of so-called hybrid banknotes are known. Special process steps are required for each banknote type in order to apply security elements to the banknote paper or to create them on the banknote paper when the banknotes are printed.
foil-based security features e.g. B. holograms, optically variable elements and / or transparent windows can be used. They are produced on foil and later applied to banknote paper to obtain a security substrate that can be printed.
Security features are known in the prior art that have at least one relief structure, usually produced by embossing, such as holograms, nanostructures, micromirrors, moiré magnifiers, etc.
the security features are film-based, and the substrate comprising at least one film is applied to a security substrate as a transfer element.
the application of individual patches is associated with high production costs. With the number of security features, the manufacturing effort for the security substrate or the document of value increases.
the WO 98/13211 A1 describes as well as the WO 2008/031170 A1 , the EP 2384901 A1 and the WO 2017/055824 A1 a security substrate.
a document of value which is made up entirely of a film body.
the film body consists of two films that are connected to each other via an intermediate layer.
the foils each have sub-wavelength structures on the sides facing the intermediate layer. All optical views that are normally generated by printing processes and presented by the document of value are now generated by these sub-wavelength structures. Other image-forming elements, such as printed elements, are deliberately excluded.
the Term "Security Substrate” is therefore understood here to include sheet-like security substrates, such as precursors for printing banknotes, cheques, etc., as well as comparatively rigid security substrates, e.g. B. precursors for security, ID or payment cards.
the invention is based on the object of creating a security substrate and a document of value in which film-based security elements can be easily combined with security elements that are generated by displaying images etc. with the greatest possible freedom of design, without producibility becoming more difficult. At the same time, a particularly good coloration of the appearance should be achieved.
the security substrate has a front and a back. It covers a certain area in plan view. It has a first carrier film which extends over at least 50%, preferably over 75% or 100% of this area.
a first, essentially opaque layer is arranged over the first carrier film and covers at least 25%, preferably more than 50% and particularly preferably more than 75% of the specific area.
a first print acceptance layer is arranged over this first opaque layer, on which a first, colored printing element is preferably formed.
a first relief structure is arranged between the first opaque layer and the first carrier film. It is provided with a first reflection-increasing coating, which brings about a first optically variable effect together with the first relief structure or alone.
the first essentially opaque layer can also be omitted and the first pressure acceptance layer can have an opacity.
a first print acceptance layer is arranged over the first carrier film, which is essentially opaque and covers at least 25%, preferably more than 50% and particularly preferably more than 75% of the specific area and on which a first, colored printing element is preferably formed .
a first relief structure is arranged between the first print acceptance layer and the first carrier film. It is provided with a first reflection-increasing coating, which brings about a first optically variable effect together with the first relief structure or alone.
opaque means an opacity of at least 50%, preferably 75% or more.
the first opaque layer or first print acceptance layer is arranged on a second carrier film, which lies between the first opaque layer or first print acceptance layer and the first relief structure.
a second carrier film which lies between the first opaque layer or first print acceptance layer and the first relief structure.
a second essentially opaque layer is provided on the side of the first relief structure opposite the first opaque layer or first pressure acceptance layer.
a second print acceptance layer is then also provided on this side, on which a second, colored printing element is formed.
the security substrate can be made from a single film with embossing of the first relief structure and embedding in protective lacquer. It is equally possible to laminate the first and the second carrier film to one another. A three-foil structure, of which the middle one is then the first carrier foil with the first relief structure, is equally possible.
the relief structure can be embossed on one side of the carrier film. It is equally possible to emboss on both sides, ie to provide a second relief structure with a second reflection-increasing coating on the other side of the first carrier film, so that there is a coated relief structure on both sides of the carrier film in an embossing lacquer applied accordingly.
the security substrate can be purely film-based. Equally, however, a combination with paper is also possible.
a paper layer can be used as the core, on the surfaces of which the foils are applied over the entire surface, one of the foils then being the first carrier foil.
foils applied to both sides of the paper core can also have relief structures. Then the already mentioned second relief structure is provided. An inversion of this structure is possible to the extent that the carrier film, which has the first (and possibly also the second) relief structure carries, paper layers are applied as the core. This can be done by lamination.
metallizations such as aluminum, gold, silver, chromium, Cr-Al, Cr-Al-Cr or alloys, e.g. B. Cu-Al in question.
color-shift or color-change coatings are possible, ie layer sequences made of metal-dielectric-metal.
semi-transparent metallization to only partially cover the colored print elements, or metal pigment inks or flakes.
the relief structure which is usually produced by embossing, can then be metalized using printing technology.
the reflection-increasing coating can be structured laterally. This is commonly referred to as demetallization and is done to reveal underlying effect or print elements.
demetallization is commonly referred to as demetallization and is done to reveal underlying effect or print elements.
a large number of means are known to the person skilled in the art for demetallization, for example so-called wash ink printing, etching techniques, metal transfer processes, printing with an oil film before vaporization, etc.
the appearance of a watermark can be produced by the lateral structuring of the opacity of the reflection-increasing coating.
the print acceptance layer can be an opaque white or a semi-transparent or fully transparent ink acceptance layer.
a low grammage can be particularly preferred in order to locally vary the transparency of the paper portion. In this way, embossed optical effects can be made visible through the paper - again a watermark appearance is obtained. As already mentioned above, gaps are also possible in the paper. This can be done by a laser cut etc. Another option is to use colored mottled fibers.
the relief structure can realize the optically variable effect using a wide variety of known techniques. Examples are hologram structures, nanostructures, micromirrors, blazed gratings, sawtooth structures, microstructures, microfocusing elements such as lenses, Fresnel lenses, concave mirrors, Fresnel concave mirrors, pinhole and slit diaphragms, each in combination with microstructures to create modulo mapper or moiré -Magnifier structures. Microfocusing elements are of particular interest in connection with two- or multi-layer foils, since the thicker composite structures then allow longer focal lengths and optical effect and printing elements can interact better with the microfocusing elements.
the micromirrors can be arranged in the z-direction at different height levels, as is particularly evident from FIG DE 102018005474 A1 , DE 102018005447 A1 or DE 102018005454 A1 is known.
customary laminating adhesives can be used. Equally, colored and/or semi-transparent laminating adhesives are possible, or laminating adhesives that contain fluorescence effects, OVI, metal flakes, etc. realize. A lamination without adhesive is equally possible, for example by melting under pressure or temperature.
the security elements formed on the security substrate by the options mentioned above can be arbitrarily distributed over the entire security substrate. This also makes it possible to design particularly individual security features, since the arbitrary distribution of the security elements that has now been achieved was not possible in the prior art.
the printed image i.e. the colored printing elements and/or the print acceptance layer
the printed image can be aligned inwards, which is of course expedient in the case of multi-layer structures.
a bare film surface can then be obtained as the outside of the security substrate, so that the security features are particularly well protected. This leads to a high resistance to circulation.
completely transparent or partially transparent windows can also be realized, for example via demetallized areas, in the relief structure and/or the reflection-increasing coating and/or the opaque layer. These windows can also be provided with semi-transparent color shift coatings etc.
the machine readability of the security substrate can be improved by applying or introducing conductive materials.
the security substrate can be produced both in the known sheet-fed banknote printing, as has been the case up to now, and in printing roll-to-roll. With the latter method, the colored print element is printed onto the already laminated end product or onto the foils to be laminated together.
first opaque layer or first print acceptance layer and/or the second opaque layer - if the latter is present - so that the security substrate becomes at least partially transparent in the area of the window or the relief structure with the reflection-increasing coating through the window is visible in the opaque layer or the first print acceptance layer.
a see-through security feature is obtained if windows are applied one on top of the other in two opaque layers or a print acceptance layer and an opaque layer.
the first opaque layer or first print acceptance layer and—if present—the second opaque layer can each be formed as a white layer, in particular as an opaque white layer.
the relief structure can also be designed in sections as a sub-wavelength structure and have a periodicity of 150 nm to 500 nm there or be configured aperiodically with a structure width of 150 nm to 500 nm.
a laterally structured opacity is preferred for the opaque layer or print acceptance layer and/or the reflection-increasing coating, so that a light/dark representation is visible when viewed through transmitted light. This, of course, applies to any opaque layers and anti-reflective coatings that may be provided.
a further layer with laterally structured opacity is provided between the first opaque layer or first pressure acceptance layer and the second opaque layer.
This can be the anti-reflective coating itself, which has gaps or recesses.
each opaque layer can also be in the form of a further print acceptance layer, so that additional print images are possible, even on the inside of the security substrate.
a translucent colored ink can be printed above or below the reflection-increasing coating, so that the optically variable effect is influenced with regard to its color impression.
a tactile embossing can be formed on the outside of the security substrate, preferably in the form of a steel intaglio print.
Each of the colored printing elements provided can be applied at least in regions over the relief structure and the reflection-increasing coating in such a way that the optically variable effect appears in a color influenced by the colored printing element.
a document of value is also provided which was produced from a security substrate of the type described and is individualized by printing on one of the print acceptance layers provided, in particular by a printed serial number etc.
metallization means a coating that consists of metal or that contains metal. Also is one Layer structure possible, consisting of a composite layer that has metal inclusions. However, it can also consist of a multi-layer structure in which one or more layers are metallic.
Embossing processes in particular direct exposure techniques, e.g. B. with the help of a laser writer in question.
the original of the embossed structure is written into a substrate coated with photoresist by direct exposure using a laser writer, and the exposed portion of the photoresist is then removed.
More complex processes for original production such as electron beam or "Focused Ion Beam" exposure processes allow a particularly fine design of the embossing structure.
an embossing stamp can be produced as a master, with which an embossing cylinder for embossing a foil web is produced "Ultimately, the structure is replicated via an embossing process, for example in UV varnish on the foil, or directly (e.g. by hot embossing into the surface of the foil). Alternatively, a nanoimprint process can be used.
the embossed foil surface is then metallised, e.g e.g. with a reflection layer and/or a structure causing a color effect, e.g. an interference layer structure, and/or a colored layer, e.g. a color-fix coating vacuum in question the film is laminated together with the intermediate layer.
FIG. 1 shows schematically a bank note 1 which is surface-structured over its entire surface with an embossing structure and is composed of a substrate body 2 which implements a security substrate and has a height H and a width B.
the substrate body 2 thus covers, in plan view, the 1 is shown, a certain area. He is in a first embodiment, the sectional view of 2 shows constructed from a sheet covering the same area.
the banknote 1 which is an example of a document of value, is presented to a viewer from the front, which in 1 is shown, provides a representation 3 as is customary for banknotes.
the representation 3 can include, for example, a graphically designed background 4, a moiré image 5, a hologram 6, a value indication 7 and a serial number 8.
a window 9 in which the bank note is partially transparent. In window 9, for example, see-through effects present, ie a motif visible on the front complements a motif visible on the back when viewed through to form a further motif.
the substrate body 2 with the height H and the width B is made up of at least one first carrier film of the same or smaller dimensions.
the carrier film covers at least 50% of the specific area, preferably the entire area.
FIG. 2 differs with regard to the embodiment of the substrate body 2. They have in common that a relief structure is provided.
3 includes the substrate body 2 multiple carrier films, in the embodiment of 2 a carrier film.
the substrate body 2 has a first (and in the embodiment of 2 also single) carrier film 10 on which a first relief structure 11 is formed in a suitable (not shown) embossing lacquer layer.
This can be embodied as a microstructure 12, for example as a diffractive hologram structure, as a subwavelength structure 13 and/or as a micromirror structure 14. how 2 shows, different types of structures can be used in the relief structure 11 .
the structures are provided with a reflection-increasing coating 15 on their upper side.
An opaque layer 17 is arranged over the reflection-increasing coating 15 by means of a leveling intermediate layer, for example in the form of a lamination 16 , on which a pressure acceptance layer 18 is implemented.
a colored printing element 19 is printed on this.
FIG. 3 shows an embodiment with substrate body 2 made of several carrier foils.
the opaque layer 17 is located on a second carrier film 20 which lies between the first relief structure 11 and the opaque layer 17 .
the lamination 16 is not only provided here over the first relief structure 11, but also on the underside of the first carrier film 10, since a third carrier film 21 is optionally provided here on the underside of the first carrier film 10, which on its underside, i.e. that of the side facing away from the first relief structure 11, a second opaque layer 22 and a second pressure acceptance layer 23 for a (in 3 not shown) second colored printing element.
the use of additional carrier foils facilitates production, since the first relief structure 11, the first and second opaque layers 17, 22 and the print acceptance layer 18, 23 are each produced on their own carrier foils and then in the direction of the symbolically in 3 Registered arrows are joined by the lamination 16.
a second, reflection-increasingly coated relief structure is optionally formed on the underside of the first carrier film 10 or on the upper side of the third carrier film 21 . For them, what was said about the first relief structure applies analogously.
FIG. 3 shows another optional feature, namely that windows 24 can be provided in the first and second opaque layer 17, 22 as well as pressure acceptance layer 18, 23, the mode of action of which has already been explained in the general part of the description. You can, other than in 3 shown, are also formed at an identical lateral position.
the pressure acceptance layer can also be combined with the opaque layer.
FIGS. 4 and 5 show exemplary designs for a substrate body 2 once from the front ( 4 ) and once from the back ( figure 5 ).
reference number 25 designates a security feature with micromirrors in a window design
reference number 26 superficial micromirror effects reference number 27 relief structures producing hologram effects
reference number 28 glazing colors on a micromirror structure as a relief structure.
figure 5 shows the rear view, corresponding to the bottom in 3 .
the elements shown are located on the back of the first carrier film 10, a further, second relief structure with a reflection-increasing coating, so that the micromirror structures are also present on the back.
the transparent window 30 that can already be seen on the front can of course also be seen on the back.
the second relief structure which is formed on the rear side of the carrier film 10, also includes holograms 31, and a colored printing element 32 is also applied to the lower print acceptance layer 23.
Reference numeral 33 designates glazing colors on a micromirror structure as a relief structure.
the carrier films are of course transparent. The same applies to the embossing lacquer coating in which the relief structures are formed.
