Patent ID: 8728613

Claim:
An identification document comprising: an inner core layer having an upper surface and a lower surface; an image receiving layer disposed on at least one of the upper surface and the lower surface of the inner core layer; the image receiving layer having one or more items of information thereon; a pattern of material embedded into the image receiving layer within at least a portion of the one or more items of information and in a predetermined configuration; the embedded pattern of material intruding into the inner core layer, wherein the embedded pattern of material is formed from a monomer material which, after contacting at least one of the one or more items of information, is cured to polymerize the monomer material, thereby yielding the embedded pattern of material; and a laminate layer disposed over the image receiving layer and the embedded pattern of material, wherein attempted delamination of the identification document using a solvent results in visually detectable tampering; and wherein the embedded pattern of material in the image receiving layer and intruding into the inner core layer substantially remains with the inner core layer upon delamination.
