Abstract

A credential with one or more security features is disclosed. The disclosed credential includes a windowed security feature. The windowed security feature is taught to include a mirror element positioned in proximity with a transparent window and a first photo-luminescent feature positioned relative to the transparent window and the mirror element such that the mirror element enhances a luminescence of the first photo-luminescent feature when viewed and illuminated through the transparent window.

Claims (38)

1. A secure document comprising:

a first clear layer;

an opaque layer beneath the first clear layer and having an opening formed therein;

a second clear layer beneath the opaque layer and having a first photo-luminescent feature on a first surface thereof;

a third clear layer beneath the second clear layer and having a second photo-luminescent feature on a first surface thereof; and

a mirror element between the second and third clear layers;

wherein at least a portion of the first photo-luminescent feature and at least a portion of the second photo-luminescent feature are aligned with the opening in the opaque layer.

2. The secure document of claim 1 , wherein at least portions of the opening in the opaque layer, the first photo-luminescent feature, the mirror element, and the second photo-luminescent feature are aligned.

3. The secure document of claim 1 , wherein the first photo-luminescent feature and second photo-luminescent feature comprise at least one of an ultraviolet ink or an infrared ink.

4. The secure document of claim 3 , further comprising a layer between the second and third clear layers.

5. The secure document of claim 4 , wherein the mirror element is provided on a surface of the layer between the second and third clear layers.

6. The secure document of claim 5 , wherein at least portions of the opening in the opaque layer, the first photo-luminescent feature, the mirror element, and the second photo-luminescent feature are aligned.

7. The secure document of claim 5 , wherein the first photo-luminescent feature comprises an ultraviolet ink of a first color and the second photo-luminescent feature comprises an ultraviolet ink of a second color, different than the first color.

8. The secure document of claim 5 , wherein the mirror element comprises at least one of a printed reflective ink or an antenna.

9. The secure document of claim 8 , wherein the first, second, and third clear layers are clear laserable polycarbonate (PC).

10. The secure document of claim 3 , wherein the first surfaces of the second and third clear layers are each outward facing surfaces.

11. The secure document of claim 1 , wherein there is at least a 150 micron separation between the mirror element and at least one of the first or second photo-luminescent features.

12. The secure document of claim 1 , wherein there is at least one of:

at least a 300 micron separation between the first photo-luminescent feature and an outer surface of the secure document; or

at least a 300 micron separation between the second photo-luminescent feature and an outer surface of the secure document.

13. A laminated secure document formed by laminating, by the application of at least one of heat or pressure, the secure document of claim 1 .

14. A secure document comprising a laminated structure made from:

a first clear layer of polycarbonate (PC);

an opaque layer of PC beneath the first clear layer and having an opening formed therein;

a second clear layer of PC beneath the opaque layer and having a first photo-luminescent feature on a first surface thereof at least partially aligned with the opening in the opaque layer;

a mirror element beneath the second clear layer and at least partially aligned with the opening in the opaque layer and the first photo-luminescent feature, wherein there is at least a 150 micron separation between the mirror element and the first photo-luminescent feature; and

a third clear layer of PC beneath the mirror element.

15. The secure document of claim 14 , wherein the mirror element is provided on a surface of a layer separate from the second clear layer.

16. The secure document of claim 14 , wherein the mirror element comprises at least one of a printed reflective ink or an antenna.

17. The secure document of claim 14 , wherein the first photo-luminescent feature comprises at least one of an ultraviolet ink or an infrared ink.

18. The secure document of claim 17 , wherein the laminated structure is further made of a second photo-luminescent feature between the mirror element and the third clear layer.

19. A secure document comprising a laminated structure made from:

a first clear layer of polycarbonate (PC);

an opaque layer of PC beneath the first clear layer and having an opening formed therein;

a second clear layer of PC beneath the opaque layer and having a first photo-luminescent feature on a first surface thereof at least partially aligned with the opening in the opaque layer;

a mirror element beneath the second clear layer and at least partially aligned with the opening in the opaque layer and the first photo-luminescent feature; and

a third clear layer of PC beneath the mirror element;

wherein there is at least a 300 micron separation between the first photo-luminescent feature and an outer surface of the laminated structure.
