Abstract

A security inlay having optically recognizable characters for an identity document comprises a first transparent layer and a second transparent layer. A color coating is situated on the first transparent layer. Furthermore, a first UV color coating, which reflects at least UV light at least in a first wavelength range, is situated on the first layer and/or on the color coating. The first and second transparent layers are connected to one another. A first portion of the optically recognizable characters is formed by blackened sections in at least one of the layers. A second portion of the optically recognizable characters is formed by the color coating. A third portion of the optically recognizable characters is formed by the UV color coating. The first and the second portions of the optically recognizable characters reflect visible light. The third portion of the optically recognizable characters reflects UV light.

First claim

The invention claimed is:

1. A security inlay having optically recognizable characters for an identity document, said security inlay comprising:
a first transparent layer,
a second transparent layer,
a color coating which is located on the first transparent layer and is transparent to infrared light and which is formed from colors cyan, magenta and yellow, and
a first UV color coating which is located on the first transparent layer and/or on the color coating and which reflects at least UV light in a first wavelength range, wherein
the first and second transparent layers are bonded together,
at least one of the first and second transparent layers comprises blackened sections,
a first portion of the optically recognizable characters is formed by the blackened sections,
a second portion of the optically recognizable characters is formed by the color coating,
a third portion of the optically recognizable characters is so formed by the UV color coating that the first and the second portion of the optically recognizable characters reflect visible light and the third portion of the optically recognizable characters reflects at least UV light in the first wavelength range, wherein the color coating and the blackened sections complement one another to form a complete image, and
a lacquer layer applied to the first transparent layer and/or to the color coating that is located on the first transparent layer and/or to the first UV color coating, wherein the lacquer layer includes nanoscale luminophores that are configured to reflect UV light of a predetermined wavelength.

2. The security inlay for an identity document as claimed in claim 1 , further comprising:
a second UV color coating which is located
on the first transparent layer, and/or
on the color coating, and/or
on the first UV color coating and which reflects at least UV light of a second wavelength range, so that
a fourth portion of the optically recognizable characters is formed by the second UV color coating.

3. The security inlay for an identity document as claimed in claim 2 , wherein
the first UV color coating reflects UV light of the first wavelength range and a third wavelength range, wherein the reflected UV light of the first and third wavelength ranges imparts to an observer a different color impression, and/or
the second UV color coating reflects UV light of the second wavelength range and a fourth wavelength range, wherein the reflected UV light of the second wavelength range and the reflected UV light of the fourth wavelength range impart different color impressions to an observer.

4. The security inlay for an identity document as claimed in claim 1 , wherein
at least one of the first and second transparent layers is blackened by an action of at least one beam of laser light.

5. The security inlay for an identity document as claimed in claim 1 , further comprising:
a transparent cover layer, and/or
an insert which comprises at least a first opaque insert layer, and/or
a third transparent layer, which is configured to be blackened by laser light, and/or
a fourth transparent layer, which is configured to be blackened by laser light, and/or
a first background color coating located on the second layer, and/or
a second background color coating located on the third layer.

6. The security inlay for an identity document as claimed in claim 5 , wherein the insert comprises:
a second opaque insert layer, and/or
an arrangement of electronic components including an antenna module and/or an RFID chip.

7. The security inlay for an identity document as claimed in claim 6 , wherein
at least one of the first, second, third and fourth transparent layers comprises a hologram element, and/or wherein
at least one hologram element is arranged between two of the first, second, third and fourth transparent layers or between one of the first, second, third and fourth transparent layers and the insert, and/or wherein
at least one of the first, second, third and fourth transparent layers is bonded with a further one of the first, second, third or fourth transparent layers and/or the cover layer and/or with the insert by lamination.

8. The security inlay for an identity document as claimed in claim 5 , wherein
the transparent cover layer and/or at least one of the transparent layers include nanoscale luminophores which are configured to reflect UV light of a predetermined wavelength.

9. The security inlay for an identity document as claimed in claim 5 , wherein
the color coating and/or the first UV color coating and/or a second UV color coating and/or the first background color coating and/or the second background color coating are formed from solvent-containing, pigment-based, inks, wherein
the solvent-containing, pigment-based, inks are suitable for dissolving and at least partially penetrating a surface of polycarbonate or polyethylene terephthalate during an application process, and/or
the color coating and/or the first UV color coating and/or the second UV color coating and/or the first background color coating and/or the second background color coating comprise silicon, silicon dioxide, mica, titanium oxide and/or tin oxide forensic markers.

10. The security inlay for an identity document as claimed in claim 1 , wherein
at least one of the first and second transparent layers is manufactured from polycarbonate or polyethylene terephthalate.

11. The security inlay for an identity document as claimed in claim 1 ,
wherein
the lacquer layer is transparent to visible light and/or infrared light and/or UV light, and/or
at least a portion of the lacquer layer comprises a manufacturing material of methacrylate, polyester acrylate or urethane acrylate, and/or
the lacquer layer comprises a heat- and/or UV-curable manufacturing material.

12. The security inlay for an identity document as claimed in claim 11 , wherein
the lacquer layer covers the color coating and/or the first UV color coating, so that
the color coating and/or the first UV color coating are completely enclosed between the first transparent layer and the lacquer layer.

13. The security inlay for an identity document as claimed in claim 11 , wherein
the first transparent layer comprises a depression, wherein the color coating and/or the first UV color coating and/or the second UV color coating are located at least partially in a region of the depression, and wherein
the depression is filled with a heat- and/or UV-curable polymer material, or with the lacquer layer, so that at least a portion of the color coating and/or of the first UV color coating and/or of the second UV color coating are enclosed by the first transparent layer and the polymer material or the lacquer layer, and wherein
the polymer material or the lacquer layer comprises nanoscale luminophores, which reflects UV light.

14. A method for producing a security inlay having optically recognizable characters for an identity document, comprising the steps:
providing a first transparent layer,
providing a second transparent layer,
producing a first portion of the optically recognizable characters by first and second blackened portions in at least one of the first and second transparent layers, by a beam of laser light,
producing a second portion of the optically recognizable characters by applying to the first transparent layer a color coating which is transparent to infrared light and is formed from colors cyan, magenta and yellow,

wherein the color coating and the first and second blackened sections complement one another to form a complete image,
producing a third portion of the optically recognizab
