The technical field to which the invention relates

The present invention relates to a protective element for banknotes, securities and documents in General.

Prior art

As you know, the problem, which is now strongly felt in various fields and in particular in the manufacture of banknotes, securities and documents in General, is the prevention of forgery of such documents; among the various known systems the most widely used systems are systems that use security threads, which may be terminated in whole or in paper strips that can be imposed from the outside on one side of the document, and onlays, which are also placed on one side of the document.

These protective elements typically have a metallic, magnetic, micro printing, the glowing filament, which in most cases uses a layer of aluminum deposited in vacuum, which is formed by the letter ["caption"], for example, by selective demetallization, and provided a magnetic zone, besieged in any way.

There are also color elements, also differently distributed, ranging from holography to change the color of the dichroic pigments technology, etc. in which the color change depends on the betrayal of the Oia angle of incidence, which falls on them.

These solutions are primarily used metallic tape, which respectively require a large sequence of operations, since it is necessary first to metalize the tape and then perform additional types of machines all required processing, which range from demetallization for forming marks before applying the magnetic material before formation of the hologram.

Obviously, this approach leads to particularly high costs and, in addition, may not always provide optimal results in terms of protection.

Disclosure of invention

The purpose of the present invention is to solve the above problems, by performing a protective element for banknotes, securities and documents in General, which creates the possibility of a combination of security features, which can be immediately detected by the user with additional security features that can be detected by the device, there is no need to resort to operations metallization strips, etc.

Under this goal the objective of the invention is to create a protective element, which can be manufactured through processes that can be performed in one pass at a very low cost.

Another objective of the present and the finding is to create a protective element, which provides the possibility of combining a variety of security features, resulting in increased potential for preventing forgery.

Another objective of the present invention to provide a protective element for banknotes, securities and documents in General, which is simplified for its performance, but it provides higher reliability guarantees.

This aim and these and other objectives which will become more apparent below, are achieved and solved by means of a protective element according to the invention, intended for banknotes, securities and documents in General, characterized in that it contains at least two adjacent zone of non-metallic materials, with one of these zones has a layer of material, refraction which varies with the angle of incidence of light, the other area has a layer of material with a constant reflection, and at least one of these areas forms the plots without a material for the formation of graphic markings, signs etc. that can be detected visually.

Brief description of drawings

Additional characteristics and advantages of the invention will become more apparent from the description of preferred but not the only option, the implementation of the protective element for banknotes, securities and documents in General, illustrated only as a non-limiting example in the accompanying drawings, in which:

Fig. 1 is a view in plan of the protective element, shown schematically in the form of filaments;

Fig. 2 is a cross-section made along the line II-II in Fig. 1;

Fig. 3 is a cross-section made along the line III-III in Fig. 1; and

figure 4 is a section made along the line IV-IV in Fig. 1.

The methods of the invention

As shown in the drawings, the protective element 1 according to the invention, intended for banknotes, securities and documents in General, which is shown schematically in the accompanying drawings in the form of thread, but with the same success can be made in the form of strips or plates, using traditional methods, as a rule, contains supporting layer 2, which is formed, for example, a complex polyester and preferably has in a particular embodiment, which should not be construed as limiting width, which is approximately 4 mm

The first layer of adhesive, indicated generally by the reference character 3, is provided on the bottom surface of the base layer 2.

A distinctive feature of the invention is that at least on one surface of the base layer 2, there are two areas without metal the materials, located nearby.

In a specific example, two zone, schematically indicated by reference items 10 and 11, are arranged longitudinally side by side, but they might be close in different ways, for example, alternating in the transverse direction, with sequential rotations, etc.

In a specific example, one of the zones, for example the area denoted by the reference position 10, is formed through the layer of material, refraction which varies in accordance with changes in the angle of the light.

In accordance with a preferred, but non-limiting embodiment the specified area obtained by holographic lacquer, which is stamped to vicinity holographic image; to complete the design color paint 15 is applied by printing or embossing.

There is a possibility instead of holographic printing to perform normal ways dichroic printing or deposition of material, which changes color in accordance with the angle of incidence of the light.

This solution eliminates the typical obtained by vacuum metallization bases that have a very high technological costs, since the device for performing such processes are very different, since they include, for example, holographically the threads, machines for applying holographic lacquer, in addition, machines for stamping and another machine for plating and machine for finishing a protective varnish, termoklejem materials, etc.

In the case of dichroic threads prior art requires the use of vacuum systems for deposition from the gas phase for applying, for example, fluoride, magnesium, chromium and then aluminum.

Education free from metal zones allows you to perform all the processes in one pass.

The other zone, i.e. the zone 11, is formed by applying a material, which has a constant reflection, such as paint, which can be the same color as the ink used for printing on embossed in the case of holographic printing, or another color.

Areas without material, i.e. negative areas denoted by the reference position 20, is provided in one of the zones, in the specific example - in area 11, and it is possible to have a graphical markings, signs, etc. that can be detected visually.

These sites are located at a distance from each other, and between two successive sections can be applied magnetic codes, denoted by the reference position 30, which is embedded in the paint layer, which forms the zone 11.

Similarly, areas without material, if required, can also b is to be provided in changing the color of the zone 10.

When the described solution can provide an innovative way of getting a protective element, since there is the possibility of performing a single pass by using any of the printing machine, such as a conventional machine for Rotogravure printing, which consistently causes the layer of material with a refraction that varies in accordance with the angle of incidence of light, and the subsequent section, in which a layer of material with a constant reflection.

In the particular case when using the layer of material with variable refractive obtained by holography, there is a section in which to apply holographic lacquer, followed by a section, which is embossed with holographic lacquer to vicinity holographic image, and an additional section in which a layer of colored paint is applied to the embossed; after that, the material constant reflection is applied by a conventional printing method.

To complete the Assembly in the case of filaments has a protective layer 40, which is applied by means of placement, if required, the intermediate layer 41 of the adhesive, which for simplicity is not shown in the drawings in longitudinal sections.

In addition, the second layer 42 of adhesive is provided on the outside.

It should be noted that, if the protective element of arr is sovan strips or plates, the sequence of layers is changed in accordance with different types of execution without changing the concept of performance in relation to the location of the zones 10 and 11.

To the above should be added that there is a possibility of applying a translucent conductive substances, such as polyaniline, in order to impart conductive properties of the protective element.

There is also the possibility of applying optically transparent substances which can be detected by the magnetic resistors or magnetic coils, or magnetic resonance.

Zone of the bearing material layer, refraction which varies in accordance with the angle of incidence can be obtained by fluorescent dyes, phosphorescent dyes, paints diversifiable absorption in the infrared region, and these substances are preferably not placed on areas without material.

These areas without material can be obtained by any known method, and can be formed by a laser beam.

Therefore, from the above description it is evident that the invention achieves the specified objectives and solves problems, and, in particular, it should be emphasized that created a protective element for banknotes, securities and documents in General, which allows you to get at least two otdelnite without a metal material, which allow to achieve the criteria of a high degree of protection with simultaneous substantial simplification of all operations in the manufacture, which eliminates the operation of applying the metallic layer or vacuum metallization, and, therefore, are the properties of the color changes that depend on different staining provided for a layer of paint that is located in the area of color change.

The invention is designed to allow numerous modifications and changes, all of which are within the scope of the attached claims.

Additionally, individual characteristics, given in relation to specific examples, may actually be replaced with other different characteristics that are typical for other examples of implementation.

In addition, it should be noted that it is assumed that, in respect of which the patent process will be established that it is already known, should not be presented claims, and it should be excluded from the claims.
