Abstract

An identification document which includes anti-counterfeiting features to provide tamper evidence in response to counterfeiting attempts includes an image receiving area having one or more fixed or variable items of information. In one embodiment, a pattern of material is embedded into the image receiving layer in the vicinity of the one or more fixed or variable items of information in a predetermined configuration. The embedded pattern is comprised of a solvent insoluble material such that attempted delamination of the document using solvents results in visually detectable tampering.

Claims (29)

1. 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.

2. The identification document of claim 1 , wherein the monomer material is a 100% monomer acrylate solution.

3. The identification document of claim 1 , wherein the polymerized embedded pattern of material is substantially clear.

4. The identification document of claim 1 , wherein curing is effected by UV curing of the monomer material to polymerize the embedded pattern of material.

5. An identification document comprising:

an inner core layer having an upper surface and a lower surface;

the inner core layer being substantially cut through from the upper surface through the lower surface to form a scored pattern in the inner core layer;

an image receiving layer disposed on at least the upper surface of the inner core layer and bonded to the inner core layer;

a laminate layer disposed on the image receiving layer and bonded to the image receiving layer; and

a release material layer disposed on the lower surface of the inner core layer and bonded to the inner core layer,

wherein:

the image receiving layer comprises one or more items of information, and the scored pattern in the inner core layer is located within at least one of the items of information,

the release material layer is located in alignment with the scored pattern in the inner core layer,

the bonding strength of the inner core layer to the image receiving layer and the laminate layer is greater than the bonding strength of the release material layer to the inner core layer, and

attempted delamination of the identification document results in the scored pattern in the inner core layer being adhered to the image receiving layer and the laminate layer, thereby providing visual evidence of tampering.

6. The identification document of claim 5 , wherein the release material layer comprises a print UV toner.

7. The identification document of claim 5 , wherein the scored pattern in the inner core layer is fully cut through from the upper surface to the lower surface of the inner core layer.

8. The identification document of claim 1 , wherein the one or more items of information is selected from the group consisting of:

an image of the identification document bearer,

a ghost image of the identifier document bearer, and

personal information of the bearer.
