Abstract

A method for manufacturing the security element transfer material, a method for the register-accurate transfer of security elements from the security element transfer material to a value document substrate, and a value document which was equipped with a security element while employing the security element transfer material, wherein the security element transfer material has a temporary carrier material and a plurality of security elements and a plurality of register mark elements which are arranged on a main area of the temporary carrier material and have a layered composite structure. Each register mark element represents a register mark or contains a register mark, and each register mark is assigned to at least one security element. Apart from the security elements and the register mark elements, the temporary carrier material is free from layered composite material.

First claim

The invention claimed is:

1. A security element transfer material for the register-accurate transfer of security elements with a layered composite structure onto a value document substrate, having:
a temporary carrier material with a first main area,
a plurality of security elements with a layered composite structure of a layered composite material and with a first main area and an opposite second main area,
wherein each security element is detachably connected on its first main area to the first main area of the temporary carrier material, and
wherein the second main area of each security element has adhesive properties for application to the value document substrate,
a plurality of register mark elements which have a layered composite structure and which are connected with their first main areas to the first main area of the temporary carrier material,
each register mark element represents a register mark or contains a register mark and has a second main area that is anti-adhesive,
a security element or a group of at least two security elements is assigned at least one register mark in each case, and
the temporary carrier material has no layered composite material on its first main area, apart from the security elements and the register mark elements.

2. The security element transfer material according to claim 1 , wherein the register mark elements themselves respectively represent register marks due to their outline shape or are carriers of register marks, the position and dimensions of which determine the position of the register marks.

3. The security element transfer material according to claim 1 , wherein the register marks can be detected by means of a light transmission detector or by means of a light reflection detector.

4. The security element transfer material according to claim 1 , wherein the security-element layered composite structure has a foil layer and/or a lacquer layer.

5. The security element transfer material according to claim 1 , wherein the temporary carrier material is a carrier composite material which has at least one first carrier substrate and one second carrier substrate which are inseparably interconnected by means of an adhesive layer.

6. The security element transfer material according to claim 1 , wherein the security element transfer material is an endless belt on which the security elements are arranged one behind the other in the longitudinal direction and optionally also next to one another in the transverse direction,
wherein the distance of the security elements from one another in the longitudinal direction is the same as or smaller than the distance that the security elements have after their application to a value-document substrate, and optionally the distance of the security elements from one another in the transverse direction is the same as the distance that the security elements have after their application to a value-document substrate.

7. A method for manufacturing a security element transfer material with a plurality of security elements of a layered composite material and with a plurality of register marks which allow a register-accurate transfer of the security elements to a value document substrate, having the following steps of:
supplying a temporary carrier material with a first main area,
building up a layered composite material on the first main area of the temporary carrier material to manufacture a starting material layered composite,
incising outline shapes of the security elements and outline shapes of register mark elements into the starting material layered composite,
wherein the register mark elements represent register marks or contain register marks and have a main area that is anti-adhesive, and
removing the layered composite material outside the outline shapes of the security elements and the register mark elements, so that the security elements and the register mark elements are the only regions on the first main area of the temporary carrier material to which layered composite material adheres.

8. The method according to claim 7 , wherein register marks are produced in the register mark elements prior to removing the layered composite material outside the outline shapes of the security elements and the register mark elements, and prior to incising the outline shapes of the security elements and the register mark elements into the starting material layered composite.

9. The method according to claim 7 , wherein to remove the layered composite material outside the outline shapes of the security elements and the register mark elements, the layered composite material is adhesively bonded to a release foil in the regions to be removed on its main area that is not connected to the temporary carrier material, and the regions of the layered composite material to be removed are pulled off the temporary carrier material together with the release foil.

10. The method according to claim 7 , wherein the temporary carrier material is a temporary carrier composite material, and the supplying of the temporary carrier material comprises manufacturing the temporary carrier material,
wherein the temporary carrier material is manufactured by inseparably connecting at least one first carrier substrate and one second carrier substrate by means of an adhesive layer to form the temporary carrier composite material.

11. A method for manufacturing a security element transfer material with a plurality of security elements of a layered composite material and with a plurality of register marks which allow a register-accurate transfer of the security elements to a value document substrate, having the following steps of:
supplying a temporary carrier material with a first main area, manufacturing a layered composite material, wherein one of the layers of the layered composite material is a foil layer,
connecting the layered composite material to the first main area of the temporary carrier material to manufacture a starting material layered composite,
incising outline shapes of the security elements and outline shapes of register mark elements into the starting material layered composite,
wherein the register mark elements represent register marks or contain register marks and have a main area that is anti-adhesive and
removing the layered composite material outside the outline shapes of the security elements and the register mark elements, so that the security elements and the register mark elements are the only regions on the first main area of the temporary carrier material to which layered composite material adheres.

12. The method according to claim 11 , wherein register marks are produced in the register mark elements prior to removing the layered composite material outside the outline shapes of the security elements and the register mark elements, and prior to incising the outline shapes of the security elements and the register mark elements into the starting material layered composite.

13. The method according to claim 11 , wherein to remove the layered composite material outside the outline shapes of the security elements and the register mark elements, the layered composite material is adhesively bonded to a release foil in the regions to be removed on its main area that is not connected to the temporary carrier material, and the regions of the layered composite material to be removed are pulled off the temporary carrier material together with the release foil.

14. The method according to claim 11 , wherein the temporary carrier material is a temporary carrier composite material, and the supplying of the temporary carrier material comprises manufacturing the temporary car
