Abstract

This disclosure describes an identification document with optical recording media, as well as related methods for making identification documents and materials used to make identification documents. The identification document includes first and second layers. The second layer is cut to form wells for receiving patches of the optical recording media. The first and second layers are joined, and the patches are placed into the wells. The first and second layers and patches form a composite structure that is used to make identification documents. In particular, in one embodiment, the patches are placed into the wells, which are filled with a curable liquid. The composite laminate structure is then joined with a core layer. Other layers may be added, such as a laminate on the opposite side of the core from the composite laminate, and image receiving layers for printing variable information.

Claims

1. An identification document comprising:

a first layer;

a second layer cut to form a well;

an optical recording media fit into the well; and

a core layer, wherein the first, second and third layers are joined together, the second layer being positioned in between the first and core layers such that the optical media is incorporated in the identification document between the first and core layers.

2. The identification document of claim 1 wherein the first, second and optical recording media are joined together in a composite structure before the composite structure is joined to the core layer.

3. A method for making a web for constructing identification documents, the method comprising:

providing first and second web layers;

cutting the second web layer to form wells for receiving patches of optical recording media;

joining the first and second web layers; and

placing the patches of optical recording media into the wells of the second layer in the joined first and second layers, wherein the first and second layers and patches are combined to form a composite web structure.

4. The method of claim 3 wherein the composite web structure is joined with a core layer to form a web of identification document material.

5. The method of claim 4 wherein the core is printed with information.

6. The method of claim 5 wherein the information includes variable information associated with a bearer of an identification document.

7. A composite web structure comprising:

a first layer;

a second layer cut to form wells;

patches of an optical recording media fit into the wells;

wherein the first and second layers are joined together, and the patches are fixed into the wells to form a web laminating structure for laminating on a substrate to make objects with optical recording media incorporated in the objects.

8. The composite web structure of claim 7 wherein the patches are fixed in the wells with a curable liquid.

9. The composite web structure of claim 7 wherein the first and second layers are joined with a clear adhesive enabling a clear optical path through the first layer to the optical recording media.
