Description

Value document

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

From EP-A 0 723 501 a value document is known with at least one window-like opening, closed by means of a translucent film, the opening being generated in the finished support which is used for the production of the value document subsequently and closing by means of a cover sheet that protrudes from the opening on all sides and fixed on the entire surface of the support, transparent at least by areas.

In this regard, the cover sheet is arranged in a depression of the support surface, which encloses the opening as a window.

However, such a thin part means a weakening of the paper support. Then in this area the value document is particularly prone to mechanical damage.

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

The aim of the invention was to provide a valuable document with at least one window-like opening, which offers a high security against counterfeiting.

The object of the invention is therefore a valuable document with at least one window-like opening, at least partially closed by means of a sheet, which is generated in the finished paper holder that serves to produce the value document. during the production of the support or later, characterized in that the sheet is applied on an elevation of the support surface that encloses the opening as a window.

The elevation preferably represents a thickening of the support.

The thickening can be generated already in line in the production of paper or later by applying, for example, a paint, a color, of paper lining or sheet elements, which do not close the opening as a window.

The application of the sheet can be carried out in such a way that the original thickening is compressed in the application operation. In this respect the compression can be so intense that the elevation after application can no longer be perceived or practically cannot be perceived.

In a further embodiment the application of the sheet can occur without or only with a weak compression of the thickening. Thus, when exploring the value document, the observer's attention is diverted, especially to the sheet applied in the thickening area.

In addition, people with visual impairment can better recognize the security element.

The application of the sheet can occur under pressure and, if necessary, under elevated temperature. In this regard, the sheet can be applied online on the paper machine or offline, for example from one roller to another roller in a printing machine or application machine.

The application can occur exactly if necessary with respect to the opening or the document of value. This enables the exact positioning of security features on the opening, so that, for example, a certain feature is visible reproducibly from the front side or the back side of the value document. It is also conceivable that the security features on the paper and on the security element, such as a watermark and a recognizable feature on the light, complement each other in the sheet and together give a new distinctive feature.

If necessary, additional thickening may also be present on the support. This offers the advantage that when stacking the value documents a uniform stack is generated and an over-rise is avoided in the area of the applied safety feature.

Safety features may also be applied to these additional thickenings, if necessary, additional openings may be present in the area of the thickening.

The openings may have different geometric shapes, for example be made round, oval, triangular or polygonal, or in the form of grooves, streamers, signs, symbols or patterns.

The sheet to be applied can be at least partially translucent and preferably have safety elements.

As a support substrate for the sheet, flexible plastic sheets are considered, for example, from PI, PP, MOPP, PE, PPS, PEEK, PEK, PEI, PSU, PAEK, LCP, PEN, PBT, PET, PA , PC, COC, POM, ABS, PVC,

fluorine polymers, such as Teflon and the like. The sheets preferably have a thickness of 5-700 µm, preferably 5-200 µm, especially preferably 5-50 µm.

In addition, flexible metal sheets, for example Al, Cu, Sn, Ni, Fe or stainless steel sheets with a thickness of 5-200 µm, preferably 10 to 80 µm, can also be used as support substrate. , especially preferably 20-50 µm. The sheets may also have undergone surface treatment, be coated or bonded by layers for example with adhesives or be painted.

In addition, as paper substrates, paper or paper compounds can also be used, for example compounds with adhesives with a weight of 20-500 g / m2, preferably 40-200 g / m2.

In addition, as support substrates, fleeces, continuous fiber fleeces, stacked fiber fleeces and the like can be used, which may be punched or calendered. Preferably such fleeces are composed of adhesives, such as PP, PET, PA, PPS and the like, although fleeces can also be used from natural fibers, if treated, such as viscose fiber fleeces. The fleeces used have a weight of approximately 20 g / m2 to 500 g / m2.

The thickness of the support substrates used is advantageously adapted to the height of the elevation. In this way a stack can be achieved without problems.

These support substrates can have safety features with optically active, optically variable, optical, metallic, metallic-looking or metallic, electrically conductive or magnetic reflections. All these characteristics can be present partially or all over the surface on the support substrate, also in different combinations.

The support substrates can have for example a paint layer, which can be structured or unstructured, for example it can be stamped. In this respect, optically active safety features such as holograms, kinegrams, diffraction structures, diffraction networks, surface reliefs, microlenses and the like can be introduced into the paint layer.

By characteristics of metallic appearance or with metallic reflections are meant coatings that reflect electromagnetic waves, preferably in the visible range, for example pigments, colors, glass or ceramic coatings, synthetic pigments or metallic effect colors. The colors of metallic effect are colors or paints for example: based on doped or non-doped semiconductor pigments, preferably in the form of inserts. Examples of pigments of this type are silicon, gallium or tellurium pigments, which have a metallic luster. These pigments and the color produced using these pigments or the paint produced therewith have a metallic luster and therefore visually have a metallic luster or metallic reflection appearance.

In this case, metallic effect colors are also understood as colors or paints produced based on mica coated with TiO2 or Fe.

In addition, so-called HRI coatings can also be applied, as layers with a high refractive index.

The most different compositions can be used as layers of color or paint. The composition of the individual layers may vary in particular according to their purpose, that is, if the individual layers serve exclusively for decorative purposes or should be a functional layer or if the layer should be both a decorative layer and a functional layer.

These layers may be pigmented or non-pigmented. As pigments, all known pigments can be used, such as titanium dioxide, zinc sulphide, kaolin, ITO, ATO, FTO, aluminum, chromium oxides and silicon as well as color pigments. In this regard, paint systems containing solvents as well as solvent-free systems can be used.

Furthermore, partial metal layers or entire surface may be present on the support substrate as a safety feature.

These layers are composed of a metal, a metal compound or an alloy. As a metal layer, layers from Al, Cu, Fe, Ag, Au, Cr, Ni, Zn, Sn, Pt, Pd, Ti and the like are suitable. Suitable metal compounds are, for example, metal oxides or sulphides, in particular TiO2, Cr, ZnS, ITO, ATO, FTO, ZnO oxides, 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 process, that is, for example, sputtered cathode or deposited in a vapor phase thermally or by means of an electronic beam.

Paramagnetic, diamagnetic and ferromagnetic substances, such as iron, nickel and cobalt or their compounds or salts (for example oxides or sulphides) can be used for the adjustment of the magnetic properties.

Especially suitable are the colors of magnetic pigments with pigments based on Fe oxides, iron, nickel, cobalt and their alloys, barium or cobalt ferrite, magnetically hard and soft iron and steel classes in aqueous dispersions or with solvent content. Solvents are, for example, i-propanol, ethyl acetate, methyl ethyl ketone, methoxypropanol and mixtures thereof.

Preferably the pigments are introduced in polymeric acrylate dispersions with a molecular weight of from 150,000 to 300,000, in acrylate-urethane dispersions, acrylate-styrene or PVC-containing dispersions or in such dispersions with solvent content.

The optical properties of the layer can be influenced by visible pigments or dyes, luminescent pigments or dyes, which emit fluorescence or phosphorescence in the UV range or in the visible IR range, effect pigments, such as liquid crystals, pearl luster, bronzes and / or multilayer color change pigments and heat sensitive colors or pigments. These can be used in all possible combinations. In addition, pigments that emit phosphorescence alone or in combination with other dyes and / or pigments can also be used.

An electrically conductive coating can be a metallic or non-metallic coating or a polymeric conductive coating, taking into account as electrically conductive metal layers essentially the aforementioned metal layers.

However, pigmented solutions with soot, graphite or silver can also be used in ethylene acrylate copolymer. Nitrocellulose, PVB, PA, acrylate or PVC or their copolymers can be used.

The percentage of pigments can be up to 90%, preferably the percentage of binder amounts to 20-70%.

The electrically conductive polymers can be, for example, polyacetylene, poly-p-phenylene, polypropyls, polythiophenes, poly-p-phenylevinylene, low molecular weight macrocyclic semiconductors, organopolysilanes, poly (sulfur nitride) and / or polyanilines and / or their derivatives . Preferably polyaniline or polythiophenes are used as electrically conductive polymers.

In addition, different properties can be combined by adding different adjuvants mentioned above. Thus it is possible to use colored and / or conductive magnetic pigments. In this regard all conductive adjuvants mentioned can be used.

Especially for coloring magnetic pigments all known soluble and non-soluble dyes or pigments can be used. Thus, for example, a brown magnetic color can be adjusted by adding metals in its color tone in a metallic manner, for example silver.

In a further embodiment, the support substrate having security features of the security element can be layered with an additional support substrate. This additional support substrate may also present security features.

The safety element may be provided on one or both sides of a layer of partial protective paint or on the entire surface.

In addition, the security element may be provided with an adhesive coating, for example a hot or cold sealing adhesive coating, an UV hardening adhesive coating or a self-adhesive coating.

The adhesive coating may be partially recessed in the area of the opening, or also be applied more thinly in the area of thickening.

With the aid of the adhesive coating, the sheet is applied on the support of the value document for at least partial closure of the openings.

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