Description

The invention relates to a security element, a value document with a security element and a method for producing a value document.

Value documents within the meaning of the invention include banknotes, stocks, bonds, certificates, vouchers, checks, air tickets, high-quality entrance tickets, labels for product security, credit or debit cards, but also other forgery-prone documents, such as passports, ID cards or other identity documents.

Value documents, in particular banknotes, are usually made of value document substrate z. B. paper substrates manufactured, the special security features such. B. have at least partially incorporated in the paper security thread and a watermark and are usually made of cotton fibers. As a further security feature so-called window films can be used. Window films are usually made essentially of a synthetic / artificial polymer / plastic. Typically, an area is taken out of the paper of a value document, so that a hole or an opening is formed. This hole is then covered again with a window film. The window film is often transparent, but may additionally be printed and / or have optical security elements such as holograms, in order to ensure better protection against counterfeiting. The particular advantage of window foils is that window foils can not be imitated by mere copying with photocopiers since the area of the window foil appears black in a copy. Also, the feel of a window film is different compared to that of paper. Consequently, copying can not achieve the different haptics of paper compared to a window film.

In the case of existing value documents with window film, however, it is disadvantageous that these window films must be introduced by means of a complex processing method into the value document in order to ensure secure integration of the window film with the remaining document of value and at the same time not impair properties such as good stackability. A typical problem with value documents with window film is that the value documents are less dimensionally stable and, for example, tend to curl up, which can also considerably complicate the processing or handling of value documents. Also, the transitions from window foil to value document substrate may be weakened areas that are more prone to mechanical damage such as tearing / tearing.

It is therefore an object of the present invention to provide a document of value with a security element, which can be produced in a simple manner and at the same time allows a high mechanical strength and easy handling of a value document with security element.

This object is solved by the subject matters of the independent claims. Preferred embodiments are defined in the dependent claims.

In particular, a security element according to this invention may include one or more films or a multilayer substrate, wherein the multilayer substrate may also comprise a combination of fabric substrates and films. The window area of the security element serves to block a hole or break in a value document substrate, e.g. B. a paper substrate of the document of value to fill or close. In other words, a security window can be provided or formed in a value document with the security element.

The top and bottom of the value document substrate as well as the window area may also be referred to as major areas. These major surfaces form (together) the main surface of a value document and render relevant information to a user.

The window area according to one of 1 to 5 is preferably transparent. Additionally or alternatively, one or both major surfaces of the window area may be printed. The window area can be designed as a patch or window. According to one example, the window substrate and / or the carrier substrate comprises as a (base) material polyethylene terephthalate (PET) and / or polypropylene (PP). Further preferably, the window portion may also include diamond-shaped, circular shapes.

A security element according to one of 1 to 5 can be prepared by various methods. For example, a security element can be produced by means of a sealing or self-adhesive operation. In order to obtain a security element, for example, in a first step, a PET substrate, preferably with a thickness of 12 μm, can be provided. On this PET substrate, which acts as a carrier substrate, a window foil is applied by means of a heat-sealing process. For this purpose, the PET substrate is coated in a window section with a transparent (seal) adhesive. Then the window foil is applied to the adhesive-coated window section. Patches can for example be applied in accordance with a self-adhesive label application in the register. Strips may also be applied in this manner, such strips being applied to a siliconized donor substrate and being severally wound or withdrawn from the donor substrate shortly before application. The window foil preferably comprises further layers, such as a release lacquer layer and / or a release foil, which are already on the window foil before the window foil is applied to the PET substrate.

Furthermore, a security element can be produced by means of a laminating process. For example, a laminating adhesive having 0.5 g / m ² to 2.0 g / m ^{2 may be} applied to both major surfaces of a support substrate. This can be done for example with roller printing and / or with a gravure printing process. By means of the laminating process, a window film is applied to the carrier substrate. The carrier substrate preferably has a thickness of approximately 12 μm, while the window film has a thickness of approximately 40 μm. The laminating adhesive layer between the carrier substrate and the window foil has a thickness of about 1 μm. This difference in thickness between adhesive and window film counteracts the risk of squeezing out of the adhesive and thus blocking of the rollers or the gravure printing machine. Furthermore you can UV-curing systems are used. The laminated strips or security elements are lined up and therefore form a long band, which is typically rolled up onto a roll. Thus, the laminated strips or the security elements are close together, resulting in a piston formation in the role. This is advantageous in terms of the winding pressure during curing.

Furthermore, security elements can be produced via laminating / release processes. This method will now be described with reference to 6a to 6c explained. First, a base substrate 600 provided. The base substrate 600 comprises at least one main surface HF _B. In connection areas 608 of the base substrate 600 becomes on the main surface HF _B a release varnish 602 applied or applied. On the release varnish / release varnish layer 602 as well as on the window area 610 of the base substrate 600 becomes an adhesive layer 604 applied. The adhesive 604 is a laminating adhesive on which a window film 606 is applied. The window film 606 is wider than a window area 610 of the base substrate 600 and protrudes into the connection areas 608 into it. The release varnish layer 602 is preferably colored for better controllability during the manufacturing process. At the edges or at the connection areas 608 adjacent borders of the window area 610 become weakened by punching, laser or knife 612 brought in. In the next step, the excess window film, the adhesive layer 604 and the release varnish layer 602 from the connection area 608 of the base substrate 600 removed or subtracted. As a result, then becomes a security element 614 , as in 6c shown, received.

The recess 706 is free of substrate 702 , The recess 706 has a shape corresponding to a negative of the shape of a window portion of the security element to be connected to the value document substrate.

The value document substrate 700 also has major surfaces HF _S.
