Abstract
Abstract The invention relates to a data carrier, in particular bank note, paper of value, identity card or the like, having a security element disposed on the surface thereof. The data carrier is provided in at least one partial area with a background layer containing at least one authenticity feature. The optically variable element is applied to this background layer such that it overlaps the latter at least partly but does not completely cover it.

Claims Analysis
Total Claims: 28
Claim 1
Independent Claim
84 words
A data carrier with a surface, the surface being provided at least in a partial area with a background layer comprising at least one testable substance indicating authenticity of the data carrier, wherein the surface of the data carrier is provided with a security element and wherein the security element at least partially overlaps the background layer such that the background layer is not completely covered by the security element and the substance is still testable in the uncovered area of the background layer.
Claim 2
Dependent Claim
84 words
A data carrier with a surface, the surface being provided at least in a partial area with a background layer comprising at least one testable substance indicating authenticity of the data carrier, wherein the surface of the data carrier is provided with a security element and wherein the security element at least partially overlaps the background layer such that the background layer is not completely covered by the security element and the substance is still testable in the uncovered area of the background layer.
Claim 3
Dependent Claim
28 words
The data carrier of claim 1, wherein the security element is an optically variable element showing different optical images when viewed from at least two different viewing angles.
Claim 4
Dependent Claim
15 words
The data carrier of claim 1, wherein the security element entirely overlaps the background layer.
Claim 5
Dependent Claim
22 words
The data carrier of claim 1, wherein the background layer comprises at least two layers, each layer comprising a different testable substance.
Claim 6
Dependent Claim
14 words
The data carrier of claim 4, wherein the layers are disposed side by side.
Claim 7
Dependent Claim
15 words
The data carrier of claim 4, wherein the layers are disposed one over the other.
Claim 8
Dependent Claim
15 words
The data carrier of claim 4, wherein the layers are disposed partly overlapping each other.
Claim 9
Dependent Claim
18 words
The data carrier of claim 1, wherein at least one additional layer is disposed below the background layer.
Claim 10
Dependent Claim
27 words
The data carrier of claim 1, wherein the testable substance is selected from the group consisting of luminescent, metallic, magnetic, electrically conductive substances and optically variable pigments.
Claim 11
Dependent Claim
24 words
The data carrier of claim 1, wherein the quantity of the background layer per surface unit decreases with the distance from the security element.
Claim 12
Dependent Claim
41 words
The data carrier of claim 1, wherein the background layer comprises a predetermined concentration per surface unit of the testable substance and wherein the concentration per surface unit decreases as the distance of the background layer from the security element increases.
Claim 13
Dependent Claim
24 words
The data carrier of claim 1, wherein an information is provided in the area of the background layer not covered by the security element.
Claim 14
Dependent Claim
19 words
The data carrier of claim 12, wherein the information is provided in form of gaps in the background layer.
Claim 15
Dependent Claim
20 words
The data carrier of claim 12, wherein the information corresponds to an information on the document or the security element.
Claim 16
Dependent Claim
16 words
The data carrier of claim 12, wherein the information is provided in form of a code.
Claim 17
Dependent Claim
81 words
A method for producing a data carrier of claim 1, comprising the steps of: providing the data carrier at least in a partial area with a background layer comprising at least one testable substance indicating authenticity of the data carrier, and applying a security element to the background layer such that the security element at least partly overlaps the background layer but does not completely cover it and the substance is still testable in the uncovered area of the background layer.
Claim 18
Dependent Claim
22 words
The method of claim 16, including in the applying step, applying the security element entirely within the area of the background layer.
Claim 19
Dependent Claim
30 words
The method of claim 16, including forming the background layer of at least two layers, each layer comprising a different testable substance and applying the layers one over the other.
Claim 20
Dependent Claim
34 words
The method of claim 16, including forming the background layer of at least two layers, each layer comprising a different testable substance and applying the layers side by side or partly overlapping each other.
Claim 21
Dependent Claim
18 words
The method of claim 16, comprising applying the background layer by printing or doctoring on the background layer.
Claim 22
Dependent Claim
25 words
The method of claim 16, including applying the background layer by a process selected from the group consisting of screen printing, flexography and halftone photogravure.
Claim 23
Dependent Claim
18 words
The method of claim 16, including applying the security element to the data carrier by a transfer process.
Claim 24
Dependent Claim
49 words
The method of claim 16, including forming the security element on the data carrier by applying a lacquer layer to the surface of the data carrier, embossing the laquer layer with an embossing tool and curing the laquer layer during contact between the embossing tool and the laquer layer.
Claim 25
Dependent Claim
15 words
The method of claim 16, including forming the security element by embossing the data carrier.
Claim 26
Dependent Claim
23 words
The method of claim 16, including forming the security element by printing an optically variable ink on the surface of the data carrier.
Claim 27
Dependent Claim
84 words
A security paper with a surface, the surface being provided at least in a partial area with a background layer comprising at least one testable substance indicating authenticity of the security paper, wherein the surface of the security paper is provided with a security element and wherein the security element at least partially overlaps the background layer such that the background layer is not completely covered by the security element and the substance is still testable in the uncovered area of the background layer.
Claim 28
Dependent Claim
84 words
A security paper with a surface, the surface being provided at least in a partial area with a background layer comprising at least one testable substance indicating authenticity of the security paper, wherein the surface of the security paper is provided with a security element and wherein the security element at least partially overlaps the background layer such that the background layer is not completely covered by the security element and the substance is still testable in the uncovered area of the background layer.
