Description

The invention relates to a value document with a window and an applied security feature.

Out EP - A 0 723 501 is a document of value with at least one window-like, closed by a translucent film opening known, the aperture produced in the serving for producing the value document finished carrier subsequently and by means of a breakthrough on all sides and on a surface of the carrier over the entire surface fixed, at least partially transparent cover is closed.

In this case, the cover film is arranged in a recess enclosing the window-like opening of the carrier surface.

However, such a thin spot means a weakening of the paper carrier. In this area, the value document is then particularly susceptible to mechanical damage in particular.

The document DE 43 34847 A1 discloses a value document with a window-like opening.

The object of the invention was to provide a document of value with at least one window-like opening, which offers increased protection against counterfeiting.

The invention is therefore a value document with at least one window-like, at least partially closed by a film opening, which is produced in the serving for the production of the value document finished paper carrier during the manufacture of the carrier or subsequently, characterized in that the film on a window-like Aperture enclosing survey of the carrier surface is applied.

The survey preferably represents a thickening of the carrier.

The thickening can be generated inline already during papermaking or subsequently by applying, for example, a varnish, a paint, paper coating or film elements which do not close the window-like opening.

The application of the film can be carried out such that the original thickening is compressed during the application process. The compression can be so strong that the survey after the application is no longer or barely palpable.

In a further embodiment, the application of the film can take place without or only with weak compression of the thickening. As a result, when the value document is scanned, the viewer's attention is directed especially to the film applied in the region of the thickening.

Visually impaired people can also better recognize the security element.

The application of the film can be carried out under pressure and optionally at elevated temperature. The film can be applied inline on the paper machine or offline, for example from roll to roll in a printing press or application machine.

If necessary, the application can be made register-accurate to the aperture or to the value document. This allows the exact positioning of security features over the aperture so that, for example, a particular feature is reproducibly visible from the front and the back of the value document, respectively. It is also conceivable that security features in the paper and the security element, such as a watermark and a visible feature in the transmitted light feature in the film and together result in a new, characteristic feature.

Optionally, further thickenings may be present on the carrier. This offers the advantage that when stacking the value documents a uniform stack is created and an increase in the area of the applied security feature is avoided.

Safety features can also be applied to these further thickenings, if necessary further openings can be present in the area of the thickenings.

The openings may have different geometric shapes, for example, round, oval, 3- or polygonal, or in the form of slits, snakes, signs, symbols or patterns.

The film to be applied may be at least partially translucent and preferably have security elements.

Examples of suitable carrier substrates of the film are flexible plastic films, for example of PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA, PC, COC, POM, ABS, PVC , Fluoropolymers such as Teflon and the like in question. The films preferably have a thickness of 5 to 700 .mu.m, preferably 5 to 200 .mu.m, particularly preferably 5 to 50 .mu.m.

Further, optionally as a support substrate and optionally flexible metal foils, for example Al, Cu, Sn, Ni, Fe or stainless steel foils with a thickness of 5 - 200 .mu.m, preferably 10 to 80 .mu.m, particularly preferably 20 - 50 microns serve. The films can also be surface-treated, coated or laminated, for example, with plastics or painted.

Further, as carrier substrates also paper or composites with paper, for example, composites with plastics with a grammage 20-500 g / m ^2, preferably 40-200 g / m ^2. be used.

Furthermore, nonwovens, such as continuous fiber webs, staple fiber webs and the like, which may be needled or may be used as the carrier substrates calendered can be used. Preferably such nonwovens consist of plastics, such as PP, PET, PA, PPS and the like, but it is also possible to use nonwovens of natural, optionally treated fibers, such as viscose fiber webs. The nonwovens used have a basis weight of about 20 g / m ² to 500 g / m ² .

The thickness of the carrier substrates used is advantageously matched to the height of the survey. This allows easy stacking can be achieved.

These carrier substrates may have security features with optically active, optically variable, optical, metallic, metallic appearing or reflecting, electrically conductive or magnetic features. All of these features may be present partially or completely on the carrier substrate, even in different combinations.

The carrier substrates may, for example, have a lacquer layer which may be unstructured or structured, for example embossed. In this case, optically active security features such as holograms, kinegrams, diffraction structures, diffraction gratings, surface reliefs, microlenses and the like may be introduced into the lacquer layer.

Metallic appearing or reflecting features are coatings which reflect electromagnetic waves, preferably in the visible range, for example pigments, paints, glass or ceramic coatings, plastic pigments or metallic effect paints. Metal effect paints are paints or lacquers, for example: based on doped or undoped semiconductor pigments, preferably in the form of platelets. Examples of such pigments are silicon, gallium or tellurium pigments which have a metallic luster. These pigments and the paint made using these pigments or the paint made therewith have one metallic shine and therefore visually appear as a metallic shiny or reflective coating.

Under metallic effect paints are understood here also on the basis of mica, coated with TiO ₂ or Fe produced paints or varnishes.

Furthermore, so-called HRI coatings, ie layers with a high refractive index, can also be applied.

As color or lacquer layers in each case a wide variety of compositions can be used. The composition of the individual layers may in particular vary according to their purpose, that is to say whether the individual layers serve exclusively for decorative purposes or should be a functional layer or whether the layer should be both a decoration layer and a functional layer.

These layers may be pigmented or unpigmented. As pigments, it is possible to use all known pigments, such as, for example, titanium dioxide, zinc sulfide, kaolin, ITO, ATO, FTO, aluminum, chromium oxides and silicon oxides, and also colored pigments. In this case, solvent-based coating systems and systems without solvents can be used.

Furthermore, partial or full-surface metallic layers may be present as a security feature on the carrier substrate.

These layers consist of a metal, a metal compound or an alloy. As the metal layer, layers of Al, Cu, Fe, Ag, Au, Cr, Ni, Zn, Sn, Pt, Pd, Ti and the like are suitable. Examples of suitable metal compounds are oxides or sulfides of metals, in particular TiO ₂ , Cr oxides, ZnS, ITO, ATO, FTO, ZnO, aluminum oxides, copper oxides or silicon oxides. Suitable alloys are, for example, Cu-Al alloys, Cu-Zn alloys and the like.

These layers can be applied in a PVD or CVD method, that is sputtered on, for example, or vapor-deposited thermally or by means of an electron beam.

To adjust the magnetic properties, paramagnetic, diamagnetic and also ferromagnetic substances, such as iron, nickel and cobalt or their compounds or salts (for example oxides or sulfides) can be used.

Particularly suitable are magnetic pigment paints with pigments based on Fe oxides, iron, nickel, cobalt and their alloys, barium or cobalt ferrites, hard and soft magnetic iron and steel grades in aqueous or solvent-containing dispersions. Examples of suitable solvents are i-propanol, ethyl acetate, methyl ethyl ketone, methoxypropanol and mixtures thereof.

Preferably, the pigments are incorporated in acrylate polymer dispersions having a molecular weight of from 150,000 to 300,000, in acrylate-urethane dispersions, acrylate-styrene or PVC-containing dispersions or in solvent-containing dispersions of this type.

The optical properties of the layer can be visualized by visible dyes or pigments, luminescent dyes or pigments which fluoresce or phosphoresce in the visible, in the UV region or in the IR region, effect pigments, such as liquid crystals, pearlescent, bronzes and / or multilayers Color change pigments and heat-sensitive colors or pigments influence. These can be used in all possible combinations. In addition, phosphorescent pigments can also be used alone or in combination with other dyes and / or pigments.

An electrically conductive coating may be a metallic or non-metallic or a polymeric conductive coating, wherein as metallic electrically conductive layers substantially the already mentioned metallic layers come into question.

But it can also with carbon black, graphite or silver pigmented dispersions or solutions in Ethylenacrylatcopolymer. Nitrocellulose, PVB, PA, acrylate or PVC or their copolymers.

The pigment content can be up to 90%, preferably the binder content is 20-70%.

The electrically conductive polymers may be, for example, polyacetylene, poly-p-phenylene, polypyrroles, polythiophenes, poly-p-phenylenevinylene, low molecular weight macrocyclic semiconductors, organopolysilanes, polysulfur nitride and / or polyanilines and / or derivatives thereof. Polyaniline or polythiophenes are preferably used as electrically conductive polymers.

Further, various properties can be combined by adding various additives mentioned above. Thus, it is possible to use colored and / or conductive magnetic pigments. All mentioned conductive additives can be used.

Especially for the dyeing of magnetic pigments it is possible to use all known soluble and non-soluble dyes or pigments. For example, a brown magnetic paint can be metallic, e.g., by adding metals in its hue, e.g. be set silvery.

In a further embodiment, the security features having carrier substrate of the security element may be laminated against another carrier substrate. Optionally, this further carrier substrate may also have security features.

The security element can be provided on one or both sides with a full-surface or partial protective lacquer view.

Furthermore, the security element can be provided with an adhesive coating, for example a hot or cold seal adhesive coating, a UV curing Be provided adhesive coating or a self-adhesive coating.

The adhesive coating may be partially recessed in the region of the opening, or be applied thinner in the region of thickening.

With the help of the adhesive coating, the film is applied to the value document carrier for at least partially closing the openings.

Furthermore, further layers or coatings, such as dirt-repellent or antibacterial coatings, can be applied to the security element at least in the region of the opening.
