Description

Security insert with tactile lacquer arrangement for an identification document and

Process for the production of such a security entrance

description

background

A security insert with a tactile lacquer arrangement for an identification document is described here. Such security inserts can be used, for example, in passports in the form of a data sheet, as well as in company ID cards, driver's licenses, ID cards, social security cards or in membership cards.

The security insert is suitable both for use in a booklet, for example a passport, and for an identification document in credit card format, for example in accordance with ISO / IEC 7810.

Such security inserts are typically essentially rectangular in a plan view and comprise optically recognizable symbols such as photos of persons, text fields, ID numbers, national emblems and / or emblems. Tactile or haptically perceptible markings of safety inserts are also known.

The goals of using security inserts are to ensure that the identification documents can be clearly identified, lasted, resilient and protected against forgery.

To increase security against forgery, security inserts for identity documents can be provided with visible features, which are difficult or at least very expensive to copy. These features serve to make forgery of the identification documents more difficult and / or to distinguish genuine identification documents from forged identification documents.

Further, security deposits for identity documents hidden and / or only under certain conditions, for example by irradiation with UV light, visible Sure ^¬ integrated features have. These features also serve to make forgery of the identification documents more difficult and / or genuine identification documents from forged ones

To distinguish between identification documents. State of the art

The German patent DE 10 2013 218 861 A1 shows a semifinished product for a security document which reveals graphic information under UV light. However, the graphic information only provides an optically recognizable security feature under UV light illumination. The graphic information is transparent for light in the visible wavelength range.

European patent EP 2 004 415 B1 shows the use of laser engraving as an invisible security feature for an identity document, but the document must be irreversibly destroyed in order to expose the laser engraving.

It is also desirable that a safety insert that has been changed by unauthorized persons can be recognized as easily as possible by an observer, for example by control personnel, as a device that is not in its original state. This should be optimally detectable with the naked eye or be able to be checked by means of simple technical devices, for example infrared light sources or UV light sources. The lack of tactile or tactile (safety) features of the safety insert should also be ascertainable as simply as possible and at the same time not or only with great difficulty be able to be concealed by further unauthorized changes to the safety insert.

A weak point of known safety inserts with tactile or tactile (safety) features is that such features cannot easily be added to an existing safety insert by unauthorized persons without such a change in the safety insert being easily recognized by control personnel. However, tactile or relief-like raised security features located on the security insert can usually be removed or scraped off comparatively easily with a sharp-edged object. If the removed security features are also personalized or merely optional security features of a security insert, the lack of them can usually not be recognized by control personnel or at least only with difficulty without aids, since a mere lack of personalized or merely optional security features does not indicate any impairment of the integrity the security deposit granted. task

Despite existing solutions, there is still a need for an improved security insert for an identification document to avoid the disadvantages described.

It is therefore an object to provide an improved security insert for an identity document and a method for producing an improved security insert for an identity document. An unauthorized reproduction of the security insert by third parties is to be made more difficult and the identity document is to be non-destructively verifiable by means of optically recognizable signs for its integrity, in particular for the integrity of tactile security features.

solution

This object is achieved by a device according to claim 1, a method for producing the device according to claim 6 and a production device according to claim 9. Advantageous embodiments are defined by the dependent claims.

A security insert for an identification document with at least one optically recognizable character and at least one tactilely detectable character comprises at least one first, at least partially transparent, layer which has blackened areas that form at least one optically recognizable character. The first at least partially transparent layer can be arranged in an interior of the security insert or form an outer layer of the security insert. For example, the first at least partially transparent layer can be arranged between at least two further layers of the safety insert or the first at least partially transparent layer can form a surface or outside of the safety insert.

At least in an undamaged state of the security insert, a lacquer arrangement is arranged on at least one layer of the security insert, which forms at least one tactilely detectable character. The at least one optically recognizable character is, at least from the perspective of a viewer of the safety insert, partially overlaid by the at least one tactilely detectable character, at least part of the outer outlines of the at least one tactilely detectable character being reproduced in an optically recognizable manner by the optically recognizable character. In particular, if the lacquer arrangement has been at least partially removed from the security insert, for example by unauthorized third parties, at least part of the outer outlines of the at least partially removed tactilely detectable sign stand out in a visually perceptible manner against the background of the optically recognizable sign formed from blackening.

The outer outlines of a tactilely detectable sign or parts of these outlines that are removed or not removed from the safety insert can be distinguished by white lines or at least lines that stand out in comparison to their immediate surroundings, especially in comparison to their immediate surroundings, in which the Draw out optically recognizable characters formed by blackenings, in particular in a gray-scale image or gray-scale characters formed by the blackening.

In other words, the outer outlines of a removed or non-removed tactilely detectable character, or at least parts of these outlines, are optically recognizable by a line-shaped brightness contrast in a gray-scale image or gray-scale character formed by the blackenings.

The outlines of a removed or non-removed tactilely detectable character or parts of these outlines can be recognizable to a viewer of the safety inlay when the safety insert is illuminated with visible light and / or infrared light and / or UV light. Optionally, the lacquer arrangement can have a production material which comprises a UV phosphor.

One advantage over known devices is that the removal of individualized or merely optional tactile signs or security features from a security insert can be easily recognized, for example by control personnel. Since an irreversible or at least difficult to conceal optically recognizable change in the security insert is left behind even when the tactile characters or security features are removed and / or changed or replaced, on the one hand a

Security against forgery of the security insert can be further increased and, on the other hand, the ability to check the integrity of the security insert can be further facilitated.

The at least one transparent layer can have a production material made of polycarbonate, polyethylene terephthalate, polyethylene terephthalate glycol or polyvinyl chloride.

Advantages of manufacturing the safety insert or individual layers of the safety insert from polycarbonate, polyethylene terephthalate, polyethylene terephthalate glycol or polyvinylchloride rid result for example from the resistance, the lightness and the flexibility of the materials.

Furthermore, the at least one transparent layer can be blackened by the action of at least one beam of laser light, for example a beam of laser light with a wavelength of 1064 nm. For this purpose, the at least one transparent layer can have additives, in particular carbon-based additives. Through the action of a beam of laser light, blackening, in particular charring, can be produced in a targeted manner in a desired intensity.

One advantage here is that blackening introduced into the interior of a layer of the security insert by means of a laser can only be removed and / or changed with difficulty subsequently without destroying the security insert.

Optionally, the safety insert can comprise further production elements, in particular further layers. In particular, the safety insert can be a multilayer safety insert which comprises several layers, in particular connected to one another by means of a lamination. For example, the security insert can comprise a second and / or a third at least partially transparent layer, each of which can be blackened by the action of laser light. Variants with further at least partially transparent layers that can be blackened by the action of laser light are expressly possible. Variants with further transparent and / or non-transparent layers that cannot be blackened by the action of laser light are also expressly possible. The further transparent layers can each be connected to the first at least partially transparent layer or to one of the further at least partially transparent layers, in particular by a lamination.

One advantage here is that a layer stack which has several interconnected layers can only be broken down into its individual layers with difficulty in a non-destructive manner, so that, for example, changing the safety insert is made considerably more difficult by replacing a single layer.

At least one of the at least partially transparent layers can have an enlarged base area compared to another transparent layer, the base area being understood to mean the dimensions of the security insert or individual transparent layers from the perspective of a viewer of the security insert. The enlarged base area of the at least one at least partially transparent layer can advantageously be used for Connection of the security insert with a booklet, in particular a passport, are used. In this case, that part of the at least one at least partially transparent layer which is larger than another transparent layer can be used to fasten the security insert in the booklet.

Optionally, one or more of the at least partially transparent layers can have a prefabricated background color application.

An advantage of using background color applications is an efficient contribution to the visually perceptible overall information of the safety insert. Furthermore, the background color applications can contain security features which further increase the security inlay's security against forgery.

Furthermore, the safety insert can optionally have a transparent cover layer, in particular a transparent cover layer made of polycarbonate, polyethylene terephthalate or polyethylene terephthalate-glycol, which is arranged on one of the transparent layers, in particular on an outer one of the transparent layers.

One advantage of the cover layer is the protection of the safety insert from negative environmental influences such as, for example, the penetration of moisture or protection from mechanical damage such as, for example, scratching of the safety insert.

In one embodiment, the first transparent layer can represent an outside of the safety insert. In other words, in one embodiment, the first transparent layer can be an outermost layer of a security insert, wherein the lacquer arrangement can in particular be arranged on this outermost layer.

In further variants, the security insert can have an opaque inlay layer which is connected to at least one of the transparent layers, in particular by a lamination, and / or a hologram element which is arranged on one of the transparent layers and / or on the opaque inlay layer, and / or or an arrangement of electronic components, in particular an antenna module and / or an RFID chip.

As a result, the forgery-proofness of the security insert can be increased further and the ability to check the security insert can be further improved.

In one embodiment, the security insert can additionally comprise an application of paint which is arranged on one of the layers of the security insert. The paint application can in particular include different color components from cyan, magenta and yellow and in particular be transparent to infrared light. For example, the paint application can be applied to the first transparent layer by means of an inkjet printing.

One advantage of using the color components from cyan, magenta and yellow is that, in one variant, the use of black color components to produce a color image that is perceptible to the viewer of the security insert can be at least partially dispensed with, without this limiting the available color spectrum . Those black portions of an overall image which are required in printing processes known as the state of the art (cyan-magenta-yellow-black printing processes, CMYK printing processes, according to ISO 2846) to create a true-color overall image can be achieved through the blackening in at least one of the layers be educated. This means that the use of black paint components in the paint application can be dispensed with, at least in part.

In other words, the application of paint, in cooperation with the at least one optically recognizable sign formed by the blackening, can produce a visually perceptible overall image, in particular a colored portrait of a person. The application of paint can partially or completely cover the blackening in the transparent layer (s) or the at least one optically recognizable character. The paint application can be arranged on the first transparent layer. The application of paint can form an outermost layer of the security insert. The paint application can be arranged on the outside of the outermost layer of the safety insert.

In a variant which can be combined with individual or all of the other features disclosed here, the paint application is located on the outside of the safety insert, and the paint arrangement is arranged directly on the paint application. The blackenings are located in the first transparent layer, which is arranged in the interior of the security insert.

Furthermore, by combining the color components of cyan, magenta and yellow, an, in particular an additional, colored black color application can be formed, which is transparent in particular for infrared light.

Thus, the outer outlines of a removed or non-removed tactilely detectable character can also be recognized as a linearly running brightness contrast in the at least one gray-scale image or gray-scale character formed by the blackenings, especially when the optically recognizable character formed by the blackenings Character is completely covered by the application of paint, for example a paint application that is nontransparent for visible light and in particular a paint application with colored black paint components. In this case, it is sufficient to illuminate the security insert for control with infrared light in order to check the integrity of the security insert.

In one embodiment, the security insert can also include a first UV ink application, which is located on a layer of the security insert, for example on the first at least partially transparent layer, and / or on the ink application. The first UV ink application can reflect at least UV light in a first wavelength range. Thus, additional optically recognizable characters can be formed by the first UV color application.

In one development, the security insert can furthermore have a second UV ink application located on a layer of the security insert and / or on the ink application and / or on the first UV ink application. The second UV color application can reflect at least UV light in a second wavelength range. Thus, further additional optically recognizable characters can be formed by the second UV ink application.

The first UV color application and / or the second UV color application can be transparent to visible light and / or infrared light.

The first UV ink application and / or the second UV ink application can, in one variant, be multicolored UV ink applications. In particular, the UV color applications can have color components from red, green, blue and white (RGBW) or from cyan, magenta, yellow and / or black (CMYK), which each reflect UV light. The use of further color components for the first and / or for the second UV color application is possible in a further development.

The first UV ink application and / or the second UV ink application can be arranged and designed to show a viewer of the security insert during the irradiation of the security insert with UV light multicolored graphic information, for example a facial image of the ID card holder, which in particular during the irradiation of the safety insert with only visible light cannot be seen by the viewer.

The first and / or the second UV color application can be bi-fluorescent in one variant. In particular, the first UV ink application can be seen by the viewer of the safety insert convey a first color impression during the irradiation of the security insert with UV light of a first wavelength and convey a second color impression during the irradiation of the security insert with UV light of a third wavelength. Furthermore, the second UV color application can convey a third color impression to the viewer of the security insert during the irradiation of the security insert with UV light of a second wavelength and convey a fourth color impression during the irradiation of the security insert with UV light of a fourth wavelength. The first, second, third and fourth color impressions can each be different from one another or at least partially identical.

For example, the first UV color application can give the viewer of the security insert during the irradiation of the security insert with UV light of a first wavelength of preferably 365 nm a color impression consisting of the color components red, green, blue and white and while the security insert is irradiated with UV Light of a third wavelength of preferably 254 nm convey a color impression from the color components green and red.

In another example, the second UV color application can give the viewer of the security insert a blue color impression during the irradiation of the security insert with UV light of a second wavelength of preferably 365 nm and during irradiation of the security insert with UV light of a fourth wavelength of preferably 313 nm convey a red color impression.

An advantage of the first UV ink application and / or the second UV ink application is that further security features can be added to the security insert, which become visible when the security insert is irradiated with UV light. If both a first UV color application and a second UV color application are used, which reflect UV light in different wavelength ranges, this enables a further increase in the forgery-proofness of the security insert, in particular since replication of the security insert is made more difficult.

The ink application and / or the first UV ink application and / or the second UV ink application can have a solvent-based, in particular pigment-based and / or UV-curable ink, which is suitable for loosening a surface made of polycarbonate or polyethylene terephthalate during an application process and / or at least partially penetrate.

One advantage of using such solvent-containing inks to form the paint application is that the security inlays are more secure against forgery. So is the For example, it is difficult to remove the paint application from the first transparent layer, for example for the purpose of replacing the first paint application by an unauthorized third party.

The paint application and / or the first UV paint application and / or the second UV paint application can contain forensic markers, in particular silicon, silicon dioxide, mica, titanium oxide and / or tin oxide.

One advantage of using such forensic markers is that the integrity of a security deposit can be checked. Although such forensic markers typically cannot be seen with the naked eye, a targeted examination of the security insert using the forensic markers can determine whether it is an original document or a forgery.

Both the color application and the first UV color application and the second UV color application are (color) layers of the security insert in the sense of this disclosure, on which in particular the lacquer arrangement can also be arranged. The color application and / or the first UV color application and / or the second UV color application can also each form an outer layer or an outside of the security insert.

The at least one tactilely detectable character can form the outer outlines of text information or image information, in particular a portrait of a person, a national emblem or a coat of arms. The at least one tactilely detectable character can also form a logo, a sequence of digits, circular knobs, stars, hearts and rectangular or round / oval surfaces.

In one embodiment, the outer outlines of the at least one tactilely detectable character can reproduce information assigned to an owner of the security insert. For example, biometric information to be assigned to the owner of the security insert and / or a passport or identity card number can be partially or fully reproduced / formed by the outer outlines of the at least one tactilely detectable character.

Furthermore, the lacquer arrangement can have a manufacturing material that can be hardened by means of UV light. One advantage here is that the lacquer arrangement can optionally be cured together with an application of ink that can be cured by means of UV light or an application of UV ink. The lacquer arrangement can comprise a plurality of tactile lacquer applications which are spaced apart from one another and which can be configured similar to one another or different from one another.

Furthermore, the lacquer arrangement can have at least one tactile lacquer application which is transparent for visible light and / or for infrared light and / or UV light, so that the at least one tactile lacquer application in particular does not optically hide the at least one optically recognizable sign for a viewer. The entire lacquer arrangement can also be transparent for visible light and / or for infrared light and / or UV light.

The lacquer arrangement can have at least one tactile transparent lacquer application which has a higher optical density than an atmosphere surrounding the safety insert. In other words, the optical refractive index of a tactile transparent lacquer application can be greater than the optical refractive index of the (room) air surrounding the safety insert. In one embodiment, the optical refractive index of a transparent lacquer application can be greater than 1.100, for example. In particular, the optical refractive index of a transparent paint application can be greater than 1,300. In a variant, a transparent lacquer application can have an optical refractive index of approximately 1.585.

Furthermore, the lacquer arrangement can have at least one tactile, transparent lacquer application with a lower optical density than one or more of the at least partially transparent layers.

In one embodiment, the lacquer arrangement can have at least one tactile lacquer application which has an at least partially rounded, in particular a partially lens-shaped or semi-elliptical, cross section. In particular, a tactile transparent lacquer application in a cross section can form a half lens shape, in particular a half collecting lens shape, on one of the layers of the security insert.

The lacquer arrangement can have at least one tactile lacquer application, which is designed and set up to optically refract light directed at least substantially perpendicularly onto the safety insert, in particular laser light directed at least substantially perpendicularly onto the safety insert. In other words, the at least one tactile paint application can be set up to change the beam path of incident (laser) light by means of optical refraction. In particular, the at least one tactile paint application can be set up to deflect incident light, in particular light incident at least substantially perpendicularly onto the safety insert, at an angle towards a To break or deflect surface normals of a surface of the security insert or to a surface normal of one of the layers of the security insert.

One advantage here is that laser light arriving at the edges or outer contours of the paint applications, with which blackening can be introduced into the at least one transparent layer below the paint arrangement, is refracted and / or reflected. The sections of the transparent layer located in the direction of the incident laser light directly below the edges or outer outlines of the paint applications are thus blackened less than would be the case if the laser light were to strike the transparent layer unhindered. In other words, the optically recognizable character or grayscale image introduced into the at least one transparent layer by means of laser light can have a contrast distortion in the area of the edges or the outer outlines of the paint jobs due to the refraction and / or reflection properties of the paint jobs.

However, the sections of the at least one transparent layer that are comparatively less blackened due to the paint applications or the line-shaped contrast distortions of the optically recognizable character or the gray-scale image in the area of the edges or outer outlines of the paint applications can only be seen in some embodiments for a viewer of the safety insert be less noticeable. At least as long as the lacquer arrangement has not been at least partially removed from the safety insert, the viewer of the safety insert follows the same optical beam path through the lacquer applications as the laser beam for producing the blackenings. The contrast distortion of the at least one optical character or grayscale image caused by the refraction and / or reflection properties of the paint application can thus be optically at least partially corrected again in some embodiments for a viewer of the security insert by the refraction and / or reflection properties of the same paint application.

If, however, at least that part of the lacquer arrangement is subsequently removed which superimposes the blackening in the at least one transparent layer or the at least one optically recognizable sign, comparatively light lines become visible to a viewer of the security insert against the background of the blackening that surrounds the edges or follow the outer contours of the removed paint applications. A subsequent change of a tactilely detectable sign of a manufactured safety insert can thus be easily understood, even if it is the tactilely detectable sign is personalized information or a merely optional security feature.

The lacquer arrangement can furthermore have a plurality of tactile lacquer applications which together form a relief structure on one of the layers of the security insert, the depth of the relief structure being less than a respective distance between the tactile lacquer applications.

Furthermore, the lacquer arrangement can have a plurality of tactile lacquer applications, wherein the respective distance between the tactile lacquer applications can be greater than a diameter of the lacquer applications. The diameter of a paint application here is defined as the minimum extent of a paint application in a direction orthogonal to a surface normal of a layer of the safety insert.

The multiple lacquer applications that can be detected by touch can have both regular and irregular spacings / distances from one another. In other words, the plurality of tactilely detectable paint jobs can be spaced apart from one another by a uniform distance or spaced apart from one another by different distances.

A method for producing a security insert for an identity document with at least one optically recognizable character and at least one tactilely detectable character comprises the steps:

- providing at least one first at least partially transparent layer;

Arranging a lacquer arrangement on a layer of the safety insert so that the lacquer arrangement forms at least one tactilely detectable character;

- Creation of at least one optically recognizable character, which partially overlays the at least one tactilely detectable character, by blackening the at least one partially transparent layer by means of a beam of laser light, the lacquer arrangement tactilely overlaying the beam of laser light at least in an edge region of the optically recognizable character superimposed detectable character breaks.

In particular, the lacquer arrangement can refract the beam of laser light at least in an edge region of the tactilely detectable character superimposed on the optically recognizable character with a positive refractive power. It goes without saying that the method disclosed here necessarily requires the production of the at least one tactilely detectable character before the production of the at least one optically recognizable character.

Optionally, the method can further comprise at least one of the following steps, wherein the additional manufacturing steps can be carried out at any point in the method:

- providing a second and / or third transparent layer;

- Provision of a cover layer and / or an opaque inlay layer;

- Provision of a hologram element and / or an arrangement of electronic components;

Connecting the layers and / or hologram elements and / or electronic component arrangements of the security insert, in particular by means of a lamination process;

- Application of a paint application which forms an overall image with the at least one optically recognizable character;

- Application of a first UV ink application;

- applying a second UV paint application;

- Drying / curing of the lacquer arrangement with UV light;

- Drying / curing of the paint application and / or the first UV paint application and / or the second UV paint application by means of UV light.

The order in which the process steps are carried out is not specified by the order in which they are named.

The application of the paint and / or the arrangement of the lacquer arrangement can each be carried out by a printing process, for example by a drop-on-demand process. In particular, the application of paint can be applied to one of the layers of the security insert before the lacquer arrangement. In other words, the paint arrangement can be arranged at least partially on the paint application.

In a further development, both the application of the paint application and the arrangement of the lacquer arrangement can be carried out by a combination device suitable for this purpose. For example, an application of paint can first be applied to a layer of the security insert and then, after it has at least partially dried, a paint arrangement can be arranged on the paint layer. The drying / hardening of the paint layer and the paint arrangement can also be carried out using a combination device suitable for this purpose. Of course, the first and / or the 15th

second UV paint application applied together with the paint application and / or the paint application and / or dried / cured.

An advantage of a combination device which is designed to arrange / apply a paint application and / or a UV paint application and / or a lacquer arrangement is an increased efficiency of the manufacturing process and thus a reduction in manufacturing costs.

In one variant of the method, an already prefabricated arrangement of interconnected, in particular laminated, layers can be provided, the interconnected layers comprising at least one first, at least partially transparent layer that can be blackened by means of laser light. Optionally, first an application of paint and then a lacquer arrangement can be applied to this prefabricated arrangement. The paint application and the lacquer arrangement can each, separately or together, be dried on, in particular by means of irradiation with UV light. Subsequently, by irradiating the interconnected layers with a beam of laser light, blackening can be produced in at least one of the interconnected layers. The blackenings can in particular be produced in an interior of the arrangement of interconnected, in particular laminated, layers. Together with the application of paint, the blackening can form an overall image, in particular a colored portrait of a person.

A device for producing a previously described security insert for an identification document comprises a handling device which is arranged and designed to fix a security insert or parts of a security insert and to convey it along a processing path. The production device further comprises a paint application device, in particular a printer, which is arranged and designed to arrange a paint application on a layer of the conveyed safety insert, so that the paint application forms at least one tactilely detectable character. A laser device is also arranged and designed to produce blackening in at least one first, at least partially transparent layer of the conveyed safety insert by means of a beam of laser light, so that at least one optically recognizable character is produced which is partially overlaid by the at least one tactilely detectable character, wherein the beam of laser light is optically refracted and / or partially reflected by the paint application during the manufacture of the safety insert at least in an edge region of the tactilely detectable sign superimposed on the optically recognizable sign to be manufactured. A printing device, which in a further development can be designed together with the lacquer application device, can also be arranged and designed to apply a paint application to a layer of the safety insert that is being conveyed.

Optionally, the manufacturing device can also have a first UV drying device that is arranged and designed to cure the paint application applied to a layer of the conveyed safety insert by means of UV light and / or a second UV drying device that is arranged and designed for this purpose to cure a layer of the promoted safety insert by means of UV light. In a further development, the first and the second UV drying device can be designed as a common device.

Furthermore, a lamination device can be arranged and designed to connect two or more layers of the security insert to one another.

It is evident to the person skilled in the art that the aspects and features described above can be combined as desired.

Detailed description of the figures

1 shows, by way of example and in a schematically simplified manner, a safety insert 100 with an optically recognizable symbol 10 and a tactilely detectable symbol 20 in a top view and a cross-sectional view of the safety insert 100.

For reasons of clarity, FIG. 1 shows only one optically recognizable character 10 and one tactilely detectable character 20, with any further embodiments with any number of optically recognizable characters and tactilely detectable characters being possible, of course.

The tactilely detectable sign 20, which is formed by a lacquer application on the security insert 100 and is circular in plan view in the example shown, partially overlays the optically recognizable sign 10.

The optically recognizable character 10, shown only schematically in FIG. 1, is in the example shown a rectangular gray-scale person portrait which shows the head and the upper body of a person against an at least not pure white background. The

Grayscale person portrait is formed by blackening produced with a laser beam in at least one layer of the security insert.

1 shows only a greatly simplified cross-sectional view of the safety insert 100 with the optically recognizable symbol 10 and the tactilely detectable symbol 20. However, an example of a possible structure of the safety insert 100 is described in more detail with reference to FIG.

A security insert 100 can in particular comprise a plurality of layers arranged one above the other and connected to one another, as shown in FIGS. 2 and 3. Just off For the sake of clarity, the interconnected layers are shown as device elements that are spaced apart from one another.

The security inlay shown in a cross-sectional view in FIG. 2 comprises a transparent cover layer 110 and a first transparent layer 120, a second transparent layer 130, a third transparent layer 140, a hologram element 150 and an opaque inlay layer 160. The hologram element 150 is in a corresponding manner formed recess of the inlay layer 160 and enclosed by the inlay layer 160 and the third transparent layer 130.

Said layers 110, 120, 130, 140, 160 are connected to one another by a lamination process. Both the first transparent layer 120 and the second and third transparent layers 130, 140 each have blackenings produced by the action of laser light, which form a sign 10 or a gray-scale image that is optically perceptible to the viewer of the safety insert.

A lacquer arrangement with three spaced apart lacquer applications 21, 22, 23 is arranged on the transparent cover layer 110 (in contrast to the examples shown in FIG. 1 or FIGS. 3 to 6), which together form the tactilely detectable sign 20 that the optically perceptible Sign 10 partially superimposed from the perspective of a viewer.

Furthermore, a color application 115 which is transparent to infrared light is arranged / printed on the first transparent layer 120, which has color components of cyan, magenta and yellow and forms an overall image with at least a part of the first optically recognizable character 10,

FIG. 3 shows a further example of a security insert 100. The security insert shown in a cross-sectional view in FIG. 3 comprises a first transparent layer 120, a second transparent layer 130, a third transparent layer 140, a hologram element 150 and an opaque inlay layer 160. The hologram element 150 is received in a correspondingly shaped recess in the inlay layer 160 and is enclosed by the inlay layer 160 and the third transparent layer 130.

The layers 120, 130, 140, 160 mentioned are connected to one another by a lamination process. In a departure from the example shown in FIG. 2, only one of the layers (the first transparent layer 120) has been produced by the action of laser light Blackenings which form a sign 10 that is optically perceptible to the viewer of the security insert or a gray-scale image.

A color application 115 which is transparent to infrared light and which has color components of cyan, magenta and yellow is arranged / printed on the first transparent layer 120. In the example shown in FIG. 3, the paint application or the paint layer 115 and the blackenings together form an overall image. The color application 115 and the blackening convey the same optical information to a viewer of the safety insert, namely once as a grayscale image (due to the blackening) and once as a color image (due to the color application), the gray-scale image and the color image complementing / superimposing one another to form the overall image.

In a departure from the example shown in FIG. 2, the security insert 100 shown in FIG. 3 does not have a cover layer. The spaced apart paint applications 21, 22, 23, which form the paint arrangement 20, are arranged directly on the paint application or the paint layer 115 in the example shown in FIG. In the example shown, a part of the paint application or the paint layer 115 is superimposed / covered over by the paint applications 21, 22, 23, while another part of the paint application or the paint layer 115 is not overlaid / covered by the paint applications 21, 22, 23. Furthermore, from the perspective of a viewer of the security insert, the lacquer applications 21, 22, 23 also partially overlay the blackenings which form the optically perceptible mark 10.

The safety inserts shown in FIGS. 2 and 3 are merely exemplary embodiments. Other embodiments of the safety insert can, for example, have more or fewer layers than the safety inserts shown in FIGS. 2 and 3 and / or other arrangement constellations of the device elements shown in FIGS. 2 and 3.

4 shows, by way of example and in a schematically simplified manner, a further example of a security insert 100 with an optically recognizable character 10 and a tactilely detectable character 20 in a top view and in a cross-sectional view along the cutting axis XI. The simplified representation of the security insert 100 in the cross-sectional view is also representative of multilayer security inserts, as shown in FIG. 2 and FIG. 3, the blackening shown in FIG. 4 only schematically simplified, which is the optically recognizable Form characters 10, 10a, can be located in different transparent layers of the security insert. 4 shows an example of a security insert for an identity document with an optically recognizable character 10, which in the example shown (analogous to the example shown in FIG. 1) is a rectangular gray-scale person portrait showing the head and upper body of a person in front of at least one does not show pure white background. The optically recognizable sign is partially covered by two lacquer applications 21, 22 which are spaced apart from one another and which together form the tactilely detectable sign 20 on the surface or on the outside of the security insert 100.

As shown in the simplified cross-sectional view of the security inlay 100, the blackenings arranged below the outer contours or the edge areas of the lacquer applications 21, 22, which are essentially semi-elliptical in cross section, have a lower blackening intensity than the respective surrounding blackenings. In other words, the sections 10a of the optically recognizable character or the grayscale person portrait, which from the perspective of a viewer are below the edges or outer outlines of the paint application, are slightly blackened than the surrounding sections 10 of the optically recognizable character or the grayscale person portrait .

The comparatively lower or less intense blackening of the at least one transparent layer below the edges or below the outer contours of the lacquer applications 21, 22 is due to the fact that the blackening only occurs after the lacquer arrangement 20 has been applied to the safety insert 100 by irradiating the safety insert , in particular the at least one transparent layer, can be produced with laser light. In particular, part of the incident laser light is reflected and / or refracted or deflected by the rounded edges of the lacquer applications in order to produce the blackening. Thus, only a reduced amount of laser light reaches the sections of the transparent layers lying below the edges or outer outlines of the lacquer applications 21, 22, while the sections of the transparent layers not lying below the rounded edges or outer outlines of the lacquer applications during the production of the blackening are not or hardly affected by laser light.

The laser light deflected or refracted by the edges or outer outlines of the paint applications 21, 22 further intensifies the contrast between the comparatively less blackened sections 10a and the sections 10 of the optically recognizable character or the gray-scale person portrait that surrounds them the laser light deflected in its beam path in addition to blackening the Sections 10 of the optically recognizable character or the grayscale person portrait, which are not positioned below the edges or the outer outlines of the lacquer applications 21, 22, contribute.

In summary, the blackenings located below the outer contours or below the edges of the lacquer applications 21, 22 from the perspective of an observer form at least one contrasting stripe 10a running through the optically recognizable character or gray-level person portrait 10 or a contrasting zone which is optically located against the background of the recognizable characters or grayscale person portraits 10 emerges.

FIG. 5 shows the arrangement already shown in FIG. 4, the lacquer arrangement 20 subsequently being removed from the security insert 100, for example in the case of an attempt at forgery. Despite the removal of the lacquer arrangement 20, the outer contours or edges of the lacquer applications 21, 22 stand out against the background of the optically recognizable character or gray-scale person portrait 10 as comparatively bright, linear contrasting stripes 10a.

FIG. 6 and FIG. 7 are intended to serve for further clarification. These likewise show a top view of an example of a security insert 100 and a schematic cross-sectional view of the security insert 100 along the cutting axis XI.

In the exemplary embodiment shown there, the first optically recognizable character 10 is a rectangular background hatching of a security insert 100, which is formed by blackening in at least one of the transparent layers of the security insert. The first optically recognizable character 10 (or the background hatching) is partially overlaid by a paint application 20, which forms a tactilely detectable character in the form of text information. The individual letters of the text information are formed by spaced apart lacquer applications.

As already stated with regard to FIG. 4, the lacquer arrangement 20 was first applied to the safety insert 100 during the manufacture of the object shown in FIG. 6. Then the optically recognizable symbol 10, in the example shown the background hatching, was produced by means of blackening or charring caused by laser light in at least one of the transparent layers of the security insert. Due to the reflection and refraction properties of the edges of the spaced-apart lacquer applications, at least for substantially perpendicularly incident laser light, an intensity of the blackenings 10a below the edges is that of the security insert 100 arranged paint applications compared to the remaining blackened areas of the first optically recognizable character 10, in the example shown compared to the background hatching, reduced.

As is made clear by means of FIG. 7, these blackenings, which are reduced in intensity along the edges of the lacquer applications, are also visually perceptible, in particular, when the lacquer arrangement 20 was subsequently removed from the safety insert 100.

The tactilely detectable sign 20 from the variants described above can also be generated in that the paint application is printed flat and overlapping with the optical sign 10 (in the manner described above). The lacquer can have one or more depressions / elevations in the area of the lacquer application, so that the thickness of the lacquer is smaller / greater there. This is achieved, for example, with an embossing stamp or a cliche. A coat of arms, a logo, a combination of letters and / or numbers, etc. can be embossed through a targeted structuring of the depressions / elevations. As with the individual paint applications 21, 22, 23, the depressions / elevations also have outer contours which are reproduced by the optical symbol 10. This is achieved by lasering through the lacquer in the area of the depressions / elevations or outlines into the card material. This variant works in combination with the paint application 115 or only in combination with the laser image.

In the variants explained above, when the card is tilted, the optical sign 10 appears immobile to a viewer; it does not offer any angle-dependent effect.

It goes without saying that the exemplary embodiments explained above are not exhaustive and do not restrict the subject matter disclosed here. In particular, it is clear to the person skilled in the art that he can combine the features described with one another as desired and / or omit various features without deviating from the subject matter disclosed here.
