6. The identification document of claim 4 , wherein the image is visible from the first side of the identification document in light reflected from the first side of the identification document and is visible from the first side of the identification document in light transmitted from the second side of the identification document through the dynamic window.

7. The identification document of claim 4 , wherein the image is invisible from the second side of the identification document in light reflected from the second side of the identification document and is visible from the second side of the identification document in light transmitted from the first side of the identification document through the dynamic window.

8. The identification document of claim 1 , wherein the dynamic window is laser engraved, and the laser engraving is visible when the identification document is viewed from the first side of the identification document with light transmitted from the second side of the identification document to the first side of the identification document through the dynamic window, and the laser engraving is not visible when the identification document is viewed from the first side of the identification document in reflected light.

9. The identification document of claim 1 , wherein the multilayer laminate is devoid of an adhesive composition.

10. The identification document of claim 1 , comprising a first tie layer laminated to a first side of the core layer and a second tie layer laminated to a second side of the core layer, wherein the second side of the core layer is opposite the first side of the core layer, and each tie layer comprises multiple sublayers of chemically modified resins.

11. The identification document of claim 10 , comprising a structural layer laminated to an outer side of each tie layer.

12. The identification document of claim 11 , comprising a receiver layer adjacent an outer side of each structural layer.

13. The identification document of claim 12 , wherein images identical to the image superimposed on the front of the dynamic window are printed on each receiver layer, wherein the identical images are superimposed such that the identical images appear to be a single image or three separate images based on an angle at which the dynamic window is viewed from the first side of the identification document in light transmitted through the dynamic window from the second side of the identification document toward the first side of the identification document.

14. The identification document of claim 10 , comprising a laser engraved image formed in at least one of the tie layers.

15. The identification document of claim 14 , wherein the laser engraved image is a hologram.

16. The identification document of claim 14 , wherein the optically variable coating is not altered by the laser engraved image.

17. The identification document of claim 1 , wherein the dynamic window comprises a clear plastic layer.

18. The identification document of claim 1 , wherein the optically variable coating is a first optically variable coating, and further comprising a second optically variable coating on the first side of the dynamic window.

19. The identification document of claim 18 , wherein the first optically variable coating is different from the second optically variable coating.

20. The identification document of claim 1 , wherein the optically variable coating completely covers the second side of the dynamic window.

21. The identification document of claim 1 , wherein the optically variable coating covers a portion of the second side of the dynamic window.

22. The identification document of claim 1 , wherein the optically variable coating comprises at least one of an optically variable pigment, an optically variable ink, an optically variable dye, and an optically variable colorant.

23. A method of fabricating an identification document, the method comprising:

forming an opening in a core layer;

positioning a dynamic window having a first side and a second side opposite the first side in the opening, the dynamic window comprising an optically variable coating on the second side of the dynamic window, wherein the first side of the dynamic window corresponds to a first side of the identification document and the second side of the dynamic window corresponds to a second side of the identification document opposite the first side of the identification document; and

superimposing an image on the first side of the dynamic window,

wherein the image is visible and the dynamic window provides a transparent background for the image when the image is viewed from the first side of the identification document in light transmitted through the dynamic window from the second side of the identification document toward the first side of the identification document, and the image is visible and the dynamic window provides a nontransparent background for the image when the image is viewed from the first side of the identification document in light reflected from the first side of the identification document; and
