Definitions
- This invention relates to a security document with a security element having at least a first layer with gaps in the form of characters or patterns, and a magnetic layer disposed below said first layer.
- the invention relates further to such a security element and to methods for producing said element and the document.
- EP 0 407 550 A1 describes a security document with an embedded security thread provided with a binary code consisting of magnetic material. Certain bit lengths are defined which are constant over the total length of the strip. The coating of a bit length with magnetic material corresponds for example to a 1 while a bit length without magnetic material corresponds to a 0.
- the binary code known from EP 0 407 550 A1 is characterized in that it is composed of alternatingly disposed separation segments and word segments whereby the word portion consists of a certain number of bit lengths and the sequence of binary values of the separation segments must not occur within this word length in order to permit clear detection of the word segments.
- This security element has the disadvantage, however, that there is no possibility of fast visual checking as is necessary in many situations of daily life.
- EP 0 516 790 A1 discloses a security document with such a security element.
- the security thread described here consists of a transparent plastic carrier layer with a metallic coating in which gaps are provided in the form of characters or patterns, the so-called negative writing. If the thread is present in the paper pulp, these gaps and the metallic surroundings are hardly visible when viewed by reflected light. When viewed by transmitted light, however, the transparent gaps stand out in strong contrast from their opaque surroundings and are thus easily recognized.
- the security element has a magnetic coating which can e.g. be disposed congruently below the metal layer so that the gaps are present congruently in both layers.
- a transparent plastic foil is first printed in the area of the later gaps with an activable ink containing foamable additives for example. Subsequently the plastic foil is provided in consecutive working steps first with a first metal layer, a magnetic layer and a second metal layer. Subsequent activation of the ink, e.g. thermal action, causes the layers to be removed in the area of the activable ink so that the gaps arise.
- the magnetic coating can be provided below the metal layer only in the edge areas of the thread and along the running direction of the element in the document, the gaps being disposed in the metal layer in the intermediate areas free from the magnetic layer.
- the transparent carrier foil of the thread is printed in the edge areas with magnetic material in the form of strips.
- the activable ink is applied in the form of the later gaps and the carrier foil then coated all over with the metal layer. The following activation of the ink finally gives rise to the gaps in the metal layer.
- the invention is based on the problem of proposing a security document with a security element which allows not only a visual check but also machine testing and offers increased protection from forgery.
- the invention is based on the finding that the extension of the negative characters is in the micron range and therefore a suitable choice of the extension of the magnetic areas and of the material parameters of the magnetic substance influencing the magnetic flux will prevent the readability of the coding from being impaired by the superimposed negative characters.
- a discontinuous magnetic layer in the form of a coding is therefore provided below the opaque layer surrounding the negative characters, the gaps also being present in the magnetic layer in the areas where the negative character gaps and the magnetic layer overlap.
- the security document has a security element with a translucent or transparent plastic layer on which a magnetic binary coding with a bit length of at least 2 to 4 mm and an opaque metal layer with negative characters are disposed, the metal layer being provided over the coding.
- the magnetic layer In the areas where the negative characters overlap the magnetic layer the magnetic layer also has gaps in the form of the characters. Under the magnetic layer one can likewise dispose, for additional visual protection of the coding, a metal layer, e.g. of aluminum or metallic ink, which likewise has the negative character gaps.
- the magnetic material and quantitative parameters are selected such that the magnetic flux is roughly twice as high as would be necessary for reading the coding on an uninterrupted thread.
- the inventive security element is produced in principle in two steps, in one case producing the magnetic coding and in the other case producing the negative writing.
- the various possibilities for producing a magnetic coding and visually recognizable negative writing will therefore first be explained independently of each other.
- a magnetic layer is preferably covered by an essentially opaque protective layer on both sides for protection from forgery
- the method variants described in the following include not only the-production of the magnetic coding itself but also the possibilities for producing a magnetic coding with a subjacent cover layer.
- This is preferably a metallic layer which can be produced by any method, such as vacuum metalization, printing with bronze inks or the like.
- other layers are of course also conceivable, such as a white color layer.
- Semitransparent layers such as a semitransparent metal layer are likewise conceivable.
- the inverse of the desired magnetic coding is printed on a carrier foil with an activable ink as a separation layer. Subsequently the lower cover layer and the magnetic layer are applied all over and uniformly distributed.
- the separation layer is then activated, e.g. by treatment with a suitable solvent.
- the dissolving process can possibly be supported by surfactants, ultrasound or mechanical brushing. This causes the separation layer and the superjacent layers to be removed.
- the magnetic coding remains on the foil.
- a continuous lower cover layer is first applied to a carrier foil.
- the inverse of the magnetic coding is printed thereon with an activable ink as a separation layer.
- the magnetic layer is applied all over and uniformly distributed.
- the separation layer is activated, for example likewise by treatment with a suitable solvent. This process can possibly be supported by surfactants, ultrasound or mechanical brushing. In this way the layers are removed in the area of the separation layer and the magnetic coding remains. However, the lower cover layer is present all over.
- the magnetic layer is printed in the desired coding directly on a carrier foil or transferred in the desired coding thereto using a transfer method.
- the carrier foil can optionally have a cover layer.
- the magnetic layer is applied all over to a carrier foil already provided all over with the lower cover layer. Subsequently the pattern of the coding is printed with a strongly adhesive ink. In a further step the magnetic layer is detached in the unprinted areas, possibly supported by ultrasound or mechanical brushing. The protective and strongly adhesive ink layer can optionally be detached subsequently.
- the magnetic layer is applied all over to a carrier layer already provided with the lower cover layer. Subsequently the inverse of the magnetic coding is printed with a caustic ink containing e.g. an acid, solvent or complexing agent. This causes the unwanted parts of the magnetic layer to be detached and the magnetic coding to remain.
- the detaching process can again be supported by surfactants, ultrasound or mechanical brushing.
- the opaque or at least partly opaque layer having the negative characters can, like the abovementioned first cover layer, consist of a metal layer, an opaque ink, a bronze ink, a hologram or the like.
- the term “opaque layer” used in the following also includes essentially opaque layers, such as semitransparent metal layers or inks with optically variable pigments such as interference layer pigments or liquid-crystal pigments. For producing the light, visually easily recognized characters against an opaque background one can fundamentally use the following possible methods.
- a translucent carrier foil is printed in the form of the later characters using a soluble ink as a separation layer. This layer structure is subsequently provided with the opaque layer. Then the separation layer is detached with a suitable solvent, which leads to detachment of the superjacent layer.
- a carrier foil is provided with at least one opaque layer by printing or vaporization. Then a strongly adhesive, translucent ink is printed on the uppermost cover layer in the form of the inverse of the later gaps, and the non-covered areas subsequently removed by being etched off or dissolved.
- a carrier foil is printed with an opaque ink containing for example bronze powders, white titanium dioxide pigments or optically variable pigments, the negative characters being left out.
- a carrier foil is printed or vaporized with at least one opaque layer. Then a caustic ink containing Lor example an acid, solvent or complexing agent is applied lo the sequence of layers in the form of the later gaps so that the subjacent layers are removed except for the carrier foil.
- Lor example an acid, solvent or complexing agent is applied lo the sequence of layers in the form of the later gaps so that the subjacent layers are removed except for the carrier foil.
- a carrier foil preferably in endless form, is provided both with the magnetic coding and with the superjacent negative writing. Subsequently this carrier foil is cut into security elements with the desired form, preferably strips or bands. In a last step this security element is connected with the security document material.
- the element can be for example embedded in the document material as a security thread or fastened all over to the document surface.
- the carrier foil can also act merely as an intermediate carrier, i.e. the layer structure consisting of negative writing and magnetic coding is transferred to the document by means of an adhesive or lacquer and the carrier foil then removed. In this case one must sure the order is right when producing the layers on the intermediate carrier so that the magnetic coding comes to lie under the negative writing on the document.

- FIG. 2 shows the basic layer structure of inventive security element 2 . It consists of carrier foil 3 , which can optionally be lacking if the element is fastened to the document surface. On carrier foil 3 there are first opaque cover layer 4 , magnetic layer 5 , second cover layer 6 and optionally transparent protective layer 7 . First opaque cover layer 4 and magnetic layer 5 are present on carrier foil 3 only in partial areas and separated from each other by intermediate areas 8 . The magnetic areas form any desired coding by their arrangement.

- One of intermediate areas 8 for example has length A while the other has a length of 2 A corresponding to the bit sequence “00”. The same applies to magnetic areas 5 shown.
- Magnetic areas 5 and lower cover layer 4 additionally have gaps 9 in the form of characters, patterns, etc. Gaps 9 constitute negative characters readable in transmission.

- Cover layer 6 disposed over magnetic areas 5 extends over total security element 2 and has only gaps 9 of the negative characters.

Abstract
The invention relates to a security document with a security element having at least a first layer with gaps in the form of characters or patterns or the like, and a discontinuous magnetic layer in the form of a coding disposed below said first layer. In the areas where the gaps and the magnetic layer overlap, the gaps are also present in the magnetic layer. The invention further relates to a security element and to methods for producing said element and the document.
Description
- This invention relates to a security document with a security element having at least a first layer with gaps in the form of characters or patterns, and a magnetic layer disposed below said first layer. The invention relates further to such a security element and to methods for producing said element and the document.
- It has been known for some time to provide security documents with plastic security threads having a magnetic coating and thus serving as a machine-readable security feature (DE 16 96 245 A1, EP 0 310 707 A1).
- To increase the forgery-proofness of this proven security feature further, it has also been proposed to provide the magnetic coating on the carrier material in discontinuous form. For example EP 0 407 550 A1 describes a security document with an embedded security thread provided with a binary code consisting of magnetic material. Certain bit lengths are defined which are constant over the total length of the strip. The coating of a bit length with magnetic material corresponds for example to a 1 while a bit length without magnetic material corresponds to a 0. The binary code known from EP 0 407 550 A1 is characterized in that it is composed of alternatingly disposed separation segments and word segments whereby the word portion consists of a certain number of bit lengths and the sequence of binary values of the separation segments must not occur within this word length in order to permit clear detection of the word segments.
- This security element has the disadvantage, however, that there is no possibility of fast visual checking as is necessary in many situations of daily life.
- It has therefore likewise been proposed to combine machine-testable security features with visual features. EP 0 516 790 A1 discloses a security document with such a security element. The security thread described here consists of a transparent plastic carrier layer with a metallic coating in which gaps are provided in the form of characters or patterns, the so-called negative writing. If the thread is present in the paper pulp, these gaps and the metallic surroundings are hardly visible when viewed by reflected light. When viewed by transmitted light, however, the transparent gaps stand out in strong contrast from their opaque surroundings and are thus easily recognized. At the same time the security element has a magnetic coating which can e.g. be disposed congruently below the metal layer so that the gaps are present congruently in both layers. In this case a transparent plastic foil is first printed in the area of the later gaps with an activable ink containing foamable additives for example. Subsequently the plastic foil is provided in consecutive working steps first with a first metal layer, a magnetic layer and a second metal layer. Subsequent activation of the ink, e.g. thermal action, causes the layers to be removed in the area of the activable ink so that the gaps arise.
- Alternatively the magnetic coating can be provided below the metal layer only in the edge areas of the thread and along the running direction of the element in the document, the gaps being disposed in the metal layer in the intermediate areas free from the magnetic layer. The transparent carrier foil of the thread is printed in the edge areas with magnetic material in the form of strips. In the intermediate areas free from the magnetic layer the activable ink is applied in the form of the later gaps and the carrier foil then coated all over with the metal layer. The following activation of the ink finally gives rise to the gaps in the metal layer.
- The invention is based on the problem of proposing a security document with a security element which allows not only a visual check but also machine testing and offers increased protection from forgery.
- The solution to this problem can be seen in the independent claims. Developments are the object of the subclaims.
- Hitherto it was impossible to combine a visual feature testable in transmission, such as the negative writing, with a magnetic coding usually consisting of spaced, opaque, magnetic areas. If the coding and the negative writing are provided on the security element independently of each other, there is a danger of the opaque areas of the coding extending into the negative characters or even covering them completely so that the characters are hardly or not at all recognizable in transmission. On the other hand, if one also provides the gaps in the magnetic layer in the overlap areas between magnetic layer and negative characters one can no longer distinguish without doubt between the actual coding and the superimposed characters when reading the coding.
- The invention is based on the finding that the extension of the negative characters is in the micron range and therefore a suitable choice of the extension of the magnetic areas and of the material parameters of the magnetic substance influencing the magnetic flux will prevent the readability of the coding from being impaired by the superimposed negative characters.
- According to the invention a discontinuous magnetic layer in the form of a coding is therefore provided below the opaque layer surrounding the negative characters, the gaps also being present in the magnetic layer in the areas where the negative character gaps and the magnetic layer overlap.
- According to a preferred embodiment the security document has a security element with a translucent or transparent plastic layer on which a magnetic binary coding with a bit length of at least 2 to 4 mm and an opaque metal layer with negative characters are disposed, the metal layer being provided over the coding. In the areas where the negative characters overlap the magnetic layer the magnetic layer also has gaps in the form of the characters. Under the magnetic layer one can likewise dispose, for additional visual protection of the coding, a metal layer, e.g. of aluminum or metallic ink, which likewise has the negative character gaps. The magnetic material and quantitative parameters are selected such that the magnetic flux is roughly twice as high as would be necessary for reading the coding on an uninterrupted thread.
- The inventive security element is produced in principle in two steps, in one case producing the magnetic coding and in the other case producing the negative writing. In the following the various possibilities for producing a magnetic coding and visually recognizable negative writing will therefore first be explained independently of each other.
- Since a magnetic layer is preferably covered by an essentially opaque protective layer on both sides for protection from forgery, the method variants described in the following include not only the-production of the magnetic coding itself but also the possibilities for producing a magnetic coding with a subjacent cover layer. This is preferably a metallic layer which can be produced by any method, such as vacuum metalization, printing with bronze inks or the like. However other layers are of course also conceivable, such as a white color layer. One can also use color layers containing iridescent or liquid-crystal pigments or other optically variable effect layers, such as holograms. Semitransparent layers such as a semitransparent metal layer are likewise conceivable.
- Production Variant M1 (for Producing a Magnetic Coding)
- The inverse of the desired magnetic coding is printed on a carrier foil with an activable ink as a separation layer. Subsequently the lower cover layer and the magnetic layer are applied all over and uniformly distributed. The separation layer is then activated, e.g. by treatment with a suitable solvent. The dissolving process can possibly be supported by surfactants, ultrasound or mechanical brushing. This causes the separation layer and the superjacent layers to be removed. The magnetic coding remains on the foil.
- Production Variant M2 (for Producing a Magnetic Coding)
- A continuous lower cover layer is first applied to a carrier foil. The inverse of the magnetic coding is printed thereon with an activable ink as a separation layer. Subsequently the magnetic layer is applied all over and uniformly distributed. In the next operation the separation layer is activated, for example likewise by treatment with a suitable solvent. This process can possibly be supported by surfactants, ultrasound or mechanical brushing. In this way the layers are removed in the area of the separation layer and the magnetic coding remains. However, the lower cover layer is present all over.
- Production Variant M3 (for Producing a Magnetic Coding)
- The magnetic layer is printed in the desired coding directly on a carrier foil or transferred in the desired coding thereto using a transfer method. The carrier foil can optionally have a cover layer.
- Production Variant M4 (for Producing a Magnetic Coding)
- The magnetic layer is applied all over to a carrier foil already provided all over with the lower cover layer. Subsequently the pattern of the coding is printed with a strongly adhesive ink. In a further step the magnetic layer is detached in the unprinted areas, possibly supported by ultrasound or mechanical brushing. The protective and strongly adhesive ink layer can optionally be detached subsequently.
- Production Variant M5 (for Producing a Magnetic Coding)
- The magnetic layer is applied all over to a carrier layer already provided with the lower cover layer. Subsequently the inverse of the magnetic coding is printed with a caustic ink containing e.g. an acid, solvent or complexing agent. This causes the unwanted parts of the magnetic layer to be detached and the magnetic coding to remain. The detaching process can again be supported by surfactants, ultrasound or mechanical brushing.
- The opaque or at least partly opaque layer having the negative characters can, like the abovementioned first cover layer, consist of a metal layer, an opaque ink, a bronze ink, a hologram or the like. The term “opaque layer” used in the following also includes essentially opaque layers, such as semitransparent metal layers or inks with optically variable pigments such as interference layer pigments or liquid-crystal pigments. For producing the light, visually easily recognized characters against an opaque background one can fundamentally use the following possible methods.
- Production Variant V1 (for Producing Gaps)
- A translucent carrier foil is printed in the form of the later characters using a soluble ink as a separation layer. This layer structure is subsequently provided with the opaque layer. Then the separation layer is detached with a suitable solvent, which leads to detachment of the superjacent layer.
- Production Variant V2 (for Producing Gaps)
- A carrier foil is provided with at least one opaque layer by printing or vaporization. Then a strongly adhesive, translucent ink is printed on the uppermost cover layer in the form of the inverse of the later gaps, and the non-covered areas subsequently removed by being etched off or dissolved.
- Production Variant V3 (for Producing Gaps)
- A carrier foil is printed with an opaque ink containing for example bronze powders, white titanium dioxide pigments or optically variable pigments, the negative characters being left out.
- Production Variant V4 (for Producing Gaps)
- A carrier foil is printed or vaporized with at least one opaque layer. Then a caustic ink containing Lor example an acid, solvent or complexing agent is applied lo the sequence of layers in the form of the later gaps so that the subjacent layers are removed except for the carrier foil.
- These separately specified methods for producing a magnetic coding and negative writing can be combined at will in order to obtain an inventive security element or security document. A carrier foil, preferably in endless form, is provided both with the magnetic coding and with the superjacent negative writing. Subsequently this carrier foil is cut into security elements with the desired form, preferably strips or bands. In a last step this security element is connected with the security document material. The element can be for example embedded in the document material as a security thread or fastened all over to the document surface. The carrier foil can also act merely as an intermediate carrier, i.e. the layer structure consisting of negative writing and magnetic coding is transferred to the document by means of an adhesive or lacquer and the carrier foil then removed. In this case one must sure the order is right when producing the layers on the intermediate carrier so that the magnetic coding comes to lie under the negative writing on the document.
- Further embodiments of the subject matter of the invention and their advantages will be explained more closely with reference to the following figures, in which:
- FIG. 1 shows a security document according to the invention,
- FIG. 2 shows a basic layer structure of the inventive security element,
- FIGS.3 to 18 show method variants for producing the inventive security element.
- FIG. 1 shows an inventive security document, here a bank note, in which
security element 2 is embedded in the form of a so-called window security thread. The security thread is quasi woven into the paper pulp during papermaking so that it passes directly to the document surface at regular intervals, which is indicated by the hatched boxes. Alternatively it is also possible, however, to embed the thread completely in the paper or to connect it with the document material such that it can be been all over on the surface. Also,security element 2 need of course not necessarily be incorporated in the form of a strip or band. In particular if the security element is applied all over to the surface of the security document, other outline forms such as a circular mark can also be advantageous. - FIG. 2 shows the basic layer structure of
inventive security element 2. It consists ofcarrier foil 3, which can optionally be lacking if the element is fastened to the document surface. Oncarrier foil 3 there are firstopaque cover layer 4,magnetic layer 5,second cover layer 6 and optionally transparentprotective layer 7. Firstopaque cover layer 4 andmagnetic layer 5 are present oncarrier foil 3 only in partial areas and separated from each other byintermediate areas 8. The magnetic areas form any desired coding by their arrangement. - According to a preferred embodiment the carrier foil can be divided into segments of equal length A, each segment corresponding to a binary bit. The coating of bit length A with magnetic material can correspond for example to a “1” and the uncoated segment of same length A to a “0”. In the shown representation,
intermediate areas 8 andmagnetic areas 5 therefore constitute integral multiples of length A. One ofintermediate areas 8 for example has length A while the other has a length of 2 A corresponding to the bit sequence “00”. The same applies tomagnetic areas 5 shown. -
Magnetic areas 5 andlower cover layer 4 additionally havegaps 9 in the form of characters, patterns, etc.Gaps 9 constitute negative characters readable in transmission. Extension B of these characters is in the micron range and thus an order of magnitude below minimum distance A between twomagnetic areas 5, which is preferably between 2 to 4 mm. -
Cover layer 6 disposed overmagnetic areas 5 extends overtotal security element 2 and has onlygaps 9 of the negative characters. Cover layers 4, 6 can consist of any opaque materials, but are preferably vaporized metal layers such as aluminum layers or optically variable layers such as holograms or printing inks with effect pigments (e.g. interference layer pigments, liquid-crystal pigments, bronze powders). - Depending on the production method it is also possible to provide
lower cover layer 4 also in the area ofcode segments 8 free from the magnetic layer. - FIGS.3 to 18 illustrate the various production methods for an inventive security element. These are different combinations of methods M1 to M5 and V1 to V4 described above.
- Combination of Methods M1 and V1
- FIG. 3 shows the various method steps necessary for obtaining the inventive security element combining method variants M1 and V1 described above.
Carrier foil 3 is printed in step a) with a first separation layer, e.g. a water-soluble ink, in the form of the visually recognizable negative characters. In second method step b) a benzine-soluble ink corresponding to the inverse pattern of the magnetic coding is printed in partial overlap with this water-soluble ink. In step c)lower cover layer 4 andmagnetic layer 5 are then applied all over and homogeneously to printedcarrier foil 3. This can be done by merely applying a coating compound or by vaporizing. In step d)ink 11 is then dissolved using the suitable solvent, e.g. benzine, thereby washing outsuperjacent layers coding segments 8 free from the magnetic layer. Sinceink 10 is not soluble in the solvent ofink 11 these printed areas remain unchanged. In further step e) this layer structure is provided with further all-overopaque layer 6. In step f)gaps 9 in the form of the negative characters are produced by treatment with a suitable solvent forink 10.

In subsequent step d) the magnetic layer is printed with stronglyadhesive ink 12 in the form of the coding.Layer 12 is resistant to solvents ofmagnetic layer 5 so that in subsequent dissolving process e) only the unprinted areas are detached, giving rise tocoding segments 8 free from the magnetic layer. In step f) the coating withsecond cover layer 6 is finally performed. The following activation ofink 10 in step g) gives rise togaps 9 in the form of the negative characters in the total layer structure.

Finallymagnetic layer 5 is printed withcaustic ink 13 in the form of the inverse magnetic coding (step d)) so that in this area the magnetic layer is removed andcoding areas 8 free from the magnetic layer arise (step e)). Then the coating withsecond cover layer 6 is performed again (step f)),ink 10 activated to produce negative characters 9 (step g)), and furtherprotective layer 7 optionally provided (step h)). - Combination of Methods M1 and V2
- FIG. 8 shows the production variant according to a combination of methods M1 and V2.

In subsequent step c)ink 11 is activated so thatcoding segments 8 free from the magnetic layer arise. In step d) the coating withsecond cover layer 6 is performed. All-overcover layer 6 is printed in step e) with strongly adhesive and solvent-resistant ink 14 in the form of the inverse later negative characters. Then the layer structure is subjected to a dissolving process (step f)) in which the areas not covered byink 14 are dissolved except for the carrier foil, giving rise tonegative characters 9. The layer structure can again be provided in optional step g) with furtherprotective layer 7. - Combination of Methods M2 and V2

case carrier foil 3 is first provided all over with lower cover layer 4 (step a)). The inverse of the magnetic coding is printed thereon with activable ink 11 (step b)).

In subsequent step d)ink 11 is activated, thereby removingmagnetic layer 5 in the area ofink 11 so thatcoding segments 8 free from the magnetic layer arise. In subsequent step e)second cover layer 6 is provided all over on the layer structure, and then printed in step f) with strongly adhesive and solvent-resistant ink 14 in the form of the inverse later negative characters. In next step g) the layer structure is treated with a solvent which detaches bothcover layers magnetic layer 5 fromcarrier foil 3 in the areas which are nor covered by solvent-resistant layer 14 (step g)). In this waynegative characters 9 are produced. Finally the total layer structure can be provided in optional step h) withprotective layer 7. - Combination of Methods M3 and V2
- FIG. 10 shows the production variant according to a combination of methods M3 and V2. In this
case carrier foil 3 is provided with first cover layer 4 (step a)), as described in the preceding production variants. In step b) the magnetic coding is produced directly by printing an ink containing magnetic pigments. In steps c) to e) one then producesnegative characters 9 by first providingsecond cover layer 6 overmagnetic coding 5, then printing it with solvent-resistant ink 14 in the form of the inverse negative characters and finally treating the layer structure with a solvent in order to producenegative characters 9. Finally the total layer structure can be provided withprotective layer 7, as in all the other variants. - Combination of Methods M4 and V2

Finallyprotective layer 7 can be applied in step e). - The production variants according to a combination of methods M2 to M5 and V3 will not be presented in the following with reference to figures since they virtually do not differ from the production of the magnetic coding in the sequence of method steps. In these variants one must merely also produce gaps for the negative characters in the magnetic layer simultaneously with the magnetic coding. The last step is fundamentally to print the second cover layer which is left out in the area of the negative characters.

In next step e)second cover layer 6 is applied, and in steps f) and g) the treatment withcaustic ink 15 is performed, giving rise tonegative characters 9. Finally the layer structure can be covered with protective layer 7 (step h)). - Combination of Methods M5 and V4
- FIG. 18 shows the production variant according to a combination of methods MS and V4. In this method, as described repeatedly above,
carrier foil 3 is first coated or vaporized all over withcover layer 4 and then with magnetic layer 5 (steps a) and b)). Then the layer structure is treated withcaustic ink 13 which detaches the unwanted parts ofmagnetic layer 5 thereby producingcoding segments 8 free from the magnetic layer (steps c) and d)) . Subsequently one produces the negative characters in the total layer structure by first applying cover layer 6 (step e)) and subsequently performing the treatment with furthercaustic ink 15 which produces the gaps or negative characters 9 (steps f) and g)). Finally the layer structure can be provided with protective layer 7 (step h)). - The untreated surface of the carrier foil can of course be provided in all method variants with further layers, such as all-over, semitransparent metal layers or luminescent prints.
- The various method steps are preferably performed in a continuous method on a plastic foil in web form. Then the finished foil is cut into security elements of the desired form and these are connected with the document material. The element can be embedded in the document material during production of the document, e.g. as a window security thread. If the element is to be disposed on the document surface the element is connected with the document material via a suitable adhesive layer, whereby the carrier foil preferably comes to lie on the side facing away from the document as a protective layer.
- Alternatively the endless carrier material can also be used as a transfer foil. In this case the carrier foil must be prepared such that the layer structure can be detached therefrom, e.g. by providing a special separation layer.
