Abstract

The present invention relates to a data carrier, especially a security document, such as an identification card, comprising authentication data comprising personalized data, the data carrier comprising a first side and a second side opposite to the first side and at least one recording layer provided with at least a first piece of authentication data of said authentication data, an array of lenticular elements being arranged at the first side of the data carrier to provide from a first predetermined angle of view an image of said at least first piece of authentication data. In order that the data carrier according to the invention shall not suffer from greyness and in order to make the data carrier esthetically appealing and manufacture it at low costs, the recording layer is a non-doped transparent PVC layer comprising said at least first piece of authentication data.

First claim

1 . A data carrier having authentication data including personalized data, the data carrier comprising: a first side and a second side opposite to the first side and at least one recording layer provided with at least a first piece of authentication data of said authentication data, an array of lenticular elements being arranged at the first side of the data carrier to provide from a first predetermined angle of view an image of said at least first piece of authentication data, wherein the recording layer is a non-doped transparent PVC layer comprising said at least first piece of authentication data.

2 . The data carrier according to claim 1 , wherein the thickness of the recording layer is 150 to 840 μm.

3 . The data carrier according to claim 1 , further comprising at least one transparent plastic layer is arranged between the recording layer and the array of lenticular elements.

4 . The data carrier according to claim 3 , further comprising an opaque layer between the recording layer and the transparent plastic layer, the opaque layer comprising a window between the recording layer and the array of lenticular elements.

5 . The data carrier according to claim 4 , further comprising a transparent PET layer between the recording layer and the trans-parent plastic layer.

6 . The data carrier according to claim 5 , characterized in that the recording layer has a thickness of 150 to 600 μm, of the transparent PET layer has a thickness of 0.25 to 0.8 times the thickness of the recording layer, and the transparent plastic layer has a thickness of 0.2 to 0.6 times the thickness of the transparent PET layer.

7 . The data carrier according to claim 5 , further comprising a second transparent plastic layer is arranged between the recording layer and the second side of the data carrier.

8 . The data carrier according to claim 7 , further comprising a second opaque layer between the recording layer and the second transparent plastic layer.

9 . The data carrier according to claim 8 , wherein the second opaque layer comprises a second window between the recording layer and the second side of the data carrier.

10 . The data carrier according to claim 9 , wherein the second window of the second opaque layer is aligned with the window of the opaque layer enabling looking from the second side to the first side of the data carrier through the second window of the second opaque layer and the window of the opaque layer.

11 . The data carrier according to claim 8 , further comprising by a second transparent PET layer between the recording layer and the second transparent plastic layer.

12 . The data carrier according to claim 11 , wherein the second transparent PET layer has a thickness 0.25 to 0.8 times the thickness of the recording layer, and the second transparent plastic layer has a thickness 0.2 to 0.6 times the thickness of the second transparent PET layer.

13 . The data carrier according to claim 3 , wherein the data carrier is in the form of a security document min the form of a card and in that the transparent plastic layer comprises said array of lenticular elements as an integral part of the transparent plastic layer.

14 . The data carrier according to claim 1 , wherein the first piece of authentication data is visible by a naked eye and is formed of a plurality of markings.

15 . The data carrier according to claim 1 , wherein the recording layer comprises a second piece of authentication data comprising personalized data, the array of lenticular elements being arranged to provide from a second predetermined angle of view ( 6 ) an image of said second piece of authentication data, said second angle of view ( 6 ) deviating from the first predetermined angle of view (a).
