Definitions
- Security feature for a document of value for a document of value, document of value, method for producing a security feature and method for checking a security feature
- the invention relates to a security feature for a document of value, a document of value, a method for producing a security feature and a method for checking a security feature.
- Documents of value such as passport and ID documents, ID cards, credit cards, bank cards and the like are being used to an increasing extent in public areas, but also in the internal area.
- Personalized information on cards or identification documents is often very difficult to recognize in difficult lighting conditions, for example in the case of transmitted light or window elements and in the case of MLI or CLIP ID security elements, as disclosed in DE 102018007207 B4, for example.
- pictures of the ID card holder are usually difficult to check.
- a security feature according to the invention for a document of value comprises at least one information unit, with a luminescent material being provided in the area of the information unit to illuminate the information unit.
- a basic idea of the present invention is that an information unit, such as a portrait, is designed such that it can be selectively illuminated. Selective means that only or exclusively the information unit or the security feature, for example in a value document, is illuminated or optically highlighted, while the rest of the security feature or the value document remains in the dark, so to speak.
- the luminescent substance With the luminescence used here, the luminescent substance is brought into an excited state by energy supplied from outside, for example by means of a UV emitter, and emits light during the transition to its ground state with the emission of photons. Thanks to the luminescent substance and its special properties, only the luminescent substance and thus this area of the security feature can be specifically highlighted or illuminated, for example with UV light.
- a UV radiator for example, an IR radiator or a laser source can be used.
- a laser source can be used in particular in combination with an anti-stoke mask.
- any source of electromagnetic waves such as UV, IR or daylight with a wavelength range of 400 - 700 nm can be used.
- the luminescent substance can be independent of the security function or feature, which means that the luminescent substance does not have to be an integral part of the security function. Rather, the luminescent substance can be a lighting or highlighting function that is functionally independent of the safety function.
- the security feature proposed here thus has the advantage of selectively or specifically emphasizing a security feature or its information unit, which leads to simpler and clearer recognition and identifiability and also to increased security against forgery.
- the luminescent substance is a photoluminescent substance.
- the photoluminescence in the form of fluorescence or phosphorescence is considered here.
- a photoluminescent substance can be excited in a simple manner by means of a UV light that is already available for checking documents of value. With fluorescence, the emission of light stops immediately after external excitation, while with phosphorescence, afterglow occurs even after excitation has ended.
- the luminescent substance can be a white fluorescent substance.
- white fluorescence when viewed under a UV light, an effect can be achieved as if a light were switched on or a light beam was focused on the security feature. In this way, simpler and clearer recognition and identifiability as well as increased protection against forgery can be achieved. A simple generation of a true color fluor image is presented. In addition, the use of white fluorescence is color-neutral, so that the color of the highlighted information unit is not changed.
- the luminescent substance is arranged behind the information unit in a viewing direction of the security feature. This creates a backlight, which increases the contrasts.
- the luminescent substance can be printed on as a dye.
- the luminescent substance is then specifically printed in the area of the information unit, for example by means of a mask.
- the luminescent substance can also comprise individual pigments which are embedded in a carrier.
- the luminescent substance can be arranged on a foil insert.
- the luminescent substance can thus be prepared before the actual production of the security feature or the document of value, which speeds up production.
- all graphically displayable elements can be designed to be illuminated by means of a luminescent substance.
- all graphically representable elements can be designed to be illuminated by means of a luminescent material.
- a document of value according to the invention such as a bank note, identification card or the like, comprises a security feature as described above.
- the security feature can be arranged, for example, in or on a substrate of the document of value. Otherwise, the same advantages and modifications as previously described apply.
- a method according to the invention for producing a security feature for a document of value comprises the steps:
- a method according to the invention for checking a security feature of a document of value comprises the steps:
- a UV radiator, an IR radiator or a laser source can be used as the light source.
- a light source is considered to be suitable if it can bring the luminescent substance into an excited state. Depending on the luminescent substance, this can also be daylight. The same advantages and modifications apply as described above.

- Fig. 8 a method for checking a security feature of a document of value.
- 1 shows a plan view of a document of value 10 in a schematic representation.
- the document of value 10 can be a bank note, a passport and identification document or the like.
- the document of value 10 is an identity document.
- the document of value 10 contains a security feature 11 in the form of a portrait of the cardholder and other personal data 12 such as the first and last name of the owner.
- the ID card can contain additional data 13, such as date of birth, nationality, issuing authority, date of issue and the like.
- the security feature 11 contains an information unit 14 here in the form of the portrait.
- the visible part of the security feature 11 is formed by the information unit 14 .
- the information unit 14 only takes up part of the visible surface of the security feature 11 .
- the information unit 14 only takes up part of the surface or main surface of the document of value 10 .
- FIG. 2 shows a section through the document of value 10 along the line II of FIG.
- FIG. 2 shows a sectional representation of the document of value 10 or of the security feature 11 from FIG. 1 along the line II.
- the document of value 10 consists of a sequence or a stack of different layers such as foils. These individual foils are joined together in a production process to form the document of value 10, for example by lamination.
- the security feature 11 can also consist of such a stack of individual layers or foils. It is also possible that the security feature 11 consists of a single foil or a few foils, which then form the information unit 14 .
- a centrally arranged design film 15 is provided as the information unit 14 .
- the design film 15 can be opaque or transparent. It is also possible for the design film 15 to be transparent only in partial areas, while being opaque in the other partial areas.
- the term foil is used for reasons of clarity. Of course, the term film also includes any form of layers such as a printed color layer.
- the information unit 14 can be formed in the design film 15 and on at least one of the two surfaces.
- a film 16 is arranged on a first, here upper side of the design film 15, which can also be opaque or transparent. Slide 16 may contain additional information or design elements. Furthermore, the foil 16 can contain safety features which can be visible or not visible in the optical range. The foil 16 can also be an adhesive layer or adhesive foil for a foil 17 lying on the outside. The outer film 17 is transparent, so that the film 16 and/or the design film 15 can be seen through the outer film 17 . In addition, adhesives or the like can be provided between the films shown here for connecting the films to one another.
- the foil 18 can correspond to the foil 16 in this case.
- the foil 19 can correspond to the foil 17 .
- a luminescent material 20 is introduced between the design film 15 and the film 16 .
- the substance In the case of luminescence, the substance is transformed into an excited state and emits light by emitting photons during the transition to its ground state.
- the photolumi nescence in the form of fluorescence or phosphorescence is considered here.
- the luminescent substance can be integrated as white fluorescence, for example.
- the luminescence substance 20 can also be referred to as a luminescence layer or as a luminescence region.
- the luminescent substance 20 specifically emphasizes defined areas of the security feature 11 or the document of value 10 . This is precisely the area in which the luminescent substance 20 is arranged. This allows the information unit 14 to be easily recognized, for example by border officials or police officers, during passport control or a driver's license check using a UV lamp or another light source, for example an IR lamp or a laser source. Activating the luminescent substance 20 results in indirect illumination of the information unit 14. Daylight can also activate the luminescent substance 20 if, for example, a passport is removed from a cover or pocket during an outdoor inspection and then exposed to daylight.
- the luminescent substance 20 can be printed onto the design film 15 as a dye. Alternatively, the luminescent substance 20 can comprise individual pigments or consist of these. Likewise, the luminescent substance 20 can be configured as an independent film.
- the document of value 10 can contain a number of security features 11 each with one or more information units 14 .
- the document of value 10 can comprise additional foils or layers, for example one or more protective layers or functional layers provided with other security elements. Foils 16 and 18 or 17 and 19 may be optional.
- the luminescent substance 20 can also be arranged at different points on the document of value 10 or the security feature 11 . In particular, the luminescent substance 20 can be arranged between layers or foils other than those shown in FIG. In particular, the luminescent substance 20 can be arranged underneath, ie behind the design film 15 in the viewing direction. The luminescent substance 20 then acts like a backlight.
- FIG. 3 shows a sectional representation of a security feature 11 or a document of value 10.
- the central design foil 15 and the further foils 16, 17, 18 and 19 are identical in their sequence to the sequence illustrated in FIG.
- the luminescent substance 20 is now arranged on an upper side of the foil 16 .
- the luminescent material 20 can also be arranged on an underside of the film 16 . It is also possible for the luminescent substance 20 to be arranged on an upper side or underside of the film 18 .
- the information unit 14 can be formed in or on the film 16, as shown in FIG. It is also possible for the information unit to be formed in the design foil 15 .
- the two films 15 and 16 can also form the information unit 14 together.
- the luminescent substance 20 highlights the information unit 14 when it is or has been illuminated.
- FIG. 4 shows a sectional view of a security feature 11 or a document of value 10, which corresponds in structural design to the security feature 11 or the document of value 10 from FIG.
- the arrangement of the luminescent substance 20 in the sequence of films also corresponds to the arrangement shown in FIG.
- the luminescent substance 20 in FIG. 4 is not formed over the entire area in the security feature 11, but only in a partial area.
- only that part of the information unit 14 is highlighted or illuminated which is located directly under the luminescent substance 20 or in its immediate vicinity.
- the remaining part of the information unit, which is located here in the design film 15, is accordingly not highlighted. It is thus possible not only to specifically emphasize a certain area of the document of value 10, but also a certain area of the security feature 11.
- FIG. 5 shows a sectional illustration of a security feature 11 or a document of value 10.
- the general arrangement or sequence of the various films again corresponds to the sequence shown in the previous figures.
- the luminescent substance 20 does not extend parallel to the foils, as shown above, but perpendicularly to the foils, ie parallel to a viewing direction.
- the luminescent substance 20 can be designed here, for example, as an insert in a window of the security feature 11 or of the document of value 10 . This arrangement of the luminescent substance 20 can enable a depth effect and/or lateral illumination.
- FIGS. 6a and 6b show a plan view of a document of value 10 with a highlighted security feature (FIG. 6a) and a security feature that is not highlighted (FIG. 6b).
- the document of value 10 is shown in a resting state or in a non-activated state of the luminescent substance 20 in the form of a fluorescent substance.
- the lighting is, for example, ordinary room lighting, which cannot bring a fluorescent substance into an excited state. Accordingly, it can be seen that the security feature 11 of the value document 10 with the information unit 14 is visually indistinguishable from the other components or areas of the Value document 10 stands out. In a darker environment, the information unit 14 in the form of the portrait is difficult to see.
- the document of value 10 is shown in an activated state of the luminescent substance 20.
- the illumination is, for example, a fluorescent lamp that puts the luminescent substance, such as a fluorescent substance, in an excited state. Accordingly, it can be seen that the security feature 11 of the document of value 10 with the information unit 14 stands out visually from the other components or areas of the document of value 10 .
- the information unit 14 in the form of the portrait appears to be illuminated and is therefore easy to recognize.
- Figure 7 shows a method for producing a security feature 11 for a document of value 10.
- an information unit 14 is provided.
- the information unit 14 can be achieved, for example, by assembling one or more films or layers.
- a luminescent substance 20 is introduced in the area of the information unit 14 in such a way that it is set up to highlight the information unit 14. In this way, a security feature 11 as shown in the figures can be produced.
- the order of the steps is not necessarily limited to this order.
- the luminescent substance 20 can also be introduced first.
- the security feature 11 produced in this way can be integrated into a document of value or formed into a document of value 10 by means of further components such as a substrate or films.
- Figure 8 shows a method for checking a security feature 11 of a document of value 10.
- the document of value 10 is irradiated with a light source.
- a fluorescent lamp for example, can serve as the light source or illumination.
- the light source is suitable for bringing the luminescent substance 20, such as a fluorescent substance, into an excited state.
- a second step 210 the security feature 11 is highlighted by a luminescent substance of the document of value 10, which is or was excited by the light source.
- the luminescent substance 20 now emits light when it transitions into its ground state, emitting photons. Accordingly, it can be seen that the security feature 11 of the value document 10 with the information unit 14 stands out visually from the other components or areas of the value document 10 .
- the information unit 14 in the form of the portrait appears to be illuminated and is therefore easy to recognize.
- the two steps 200 and 210 can also take place at the same time.
- a third step 220 the highlighted security feature 11 is checked.
- the now highlighted security feature 11 or its information unit 14 can now be checked visually in a simple manner and without confusion, since it is illuminated by the luminescent substance 20 or is backlit.
- All three steps 200, 210 and 220 can also take place at the same time.
