Data carrier card having a security thread
View Patent ↗A data carrier card, in particular a chip and/or magnetic strip card, has a card body comprising one or more films and a security thread integrated in the card body. The security thread, or at least a substrate of the security thread, is coextruded in the form of a thread strip in one of the films.
1. A data carrier card comprising:
a card body including one or several foils and a security thread integrated in the card body,
wherein at least one of the foils is manufactured by coextrusion and includes at least a thread strip and a bordering strip lying side by side in the area dimension of said at least one of the foils,
wherein the thread strip differs in at least one material property from the bordering strip, and to the thread strip there is applied, as an overprint or underprint, at least one printed layer, and
wherein the thread strip forms, by cooperation with the at least one printed layer, the security thread or a part of the security thread.
2. The data carrier card according to claim 1 , wherein a visually perceptible effect arises by the cooperation of the thread strip and the at least one printed layer.
3. The data carrier card according to claim 1 , wherein a metallically lustrous effect and/ or an interference effect arises by the cooperation of the thread strip and the at least one printed layer.
4. The data carrier card according to claim 1 , wherein the thread strip is configured to be transmissive.
5. The data carrier card according to claim 4 , wherein the card body or at least a card core of the card body has two or more than two coextruded strip foils arranged one over the other, which respectively have a thread strip, wherein the respective thread strips lie one over the other.
6. The data carrier card according to claim 1 , wherein at least one foil forms an inner foil of the card body and at least one printed layer is configured on this inner foil.
7. The data carrier card according to claim 1 , wherein the thread strip and/ or a printing ink of a printed layer contains color-shift pigments, silver-colored, goldcolored and/ or lustrous pigments or substances, fluorescent or thermochromic pigments or substances, laser-sensitive pigments or substances, such as carbon black, and/ or other kinds of elements such as Charms, taggants and/ or mottling fibers.
8. The data carrier card according to claim 1 , wherein the printed layer applied to the thread strip is an ink, rainbow or mirror layer, which is applied as a screen or offset printed layer.
9. The data carrier card according to claim 1 , wherein the printed layer is configured on the thread strip to be congruent.
10. The data carrier card according to claim 1 , wherein the thread strip contains fluorescent pigments or substances and on both sides on the at least one foil there is respectively arranged a UV-absorbing foil.
11. The data carrier card according to claim 1 , wherein the security thread makes available to a viewer mutually different items of incident light and transmitted light information.
12. The data carrier card according to claim 1 , wherein cylindrical lenses are arranged on the data carrier card above the security thread and/or at a margin of the card body.
13. The data carrier card according to claim 1 , wherein the thread strip has a laser inscription produced by laser radiation.
14. The data carrier card according to claim 1 , wherein on the at least one foil there is arranged at least one further foil, wherein the foils are mutually laminated or coextruded and the further foil is a cover layer or part of a card core of the card body and is configured to be uniform over the full area and is transparent or translucent.
15. The data carrier card according to claim 1 , wherein the data carrier card has at least one cover layer which contains laser-sensitive pigments or substances.
16. The data carrier card according to claim 1 , wherein the printed layer extends, beside the thread strip, to further regions of the foil coextruded with the thread strip.
17. The data carrier card according to claim 1 , wherein the thread strip has a width between 0.5 and 10 mm, and/ or with a width between 1 and 20% of the width of the strip foil.
18. The data carrier card according to claim 1 , wherein the at least one foil is a coextruded strip foil, in which the thread strip is surrounded by two bordering strips, which each have an identical condition that is different from the thread strip.
19. A method for manufacturing a data carrier card having a card body comprising one or several foils and a security thread integrated in the card body, according to claim 1 , comprising the steps of:
coextruding a thread strip with at least one of the foils,
applying a printed layer to the thread strip, which produces a tamper-resistant security feature by cooperation with the thread strip and together with the thread strip forms the security thread or a part of the security thread.
20. The method according to claim 19 , wherein the thread strip and/ or another foil of the card body, contains laser-sensitive pigments or substances and the data carrier card is personalized by laser radiation.
