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.
Claims14
An identification document comprising:
- an inner core layer of material having upper and lower surfaces;
- an image receiving layer disposed on at least one of the upper and lower surfaces of the inner core layer;
- the image receiving layer having one or more fixed or variable items of information thereon;
- a pattern of material embedded into the image receiving layer in the vicinity of the one or more fixed or variable items of information and in a predetermined configuration;
- the embedded pattern further intruding into the inner core layer;
- a laminate layer disposed over the image receiving layer and embedded pattern;
- and
- wherein, attempted delamination of the document using solvents results in visually detectable tampering.
An identification document comprising:
- an inner core layer of material having upper and lower surfaces;
- the inner core layer being substantially cut through from the upper surface through the lower surface to form a scored pattern;
- an image receiving layer disposed on at least the upper surface of the core layer and bonded to the core layer;
- a laminate layer disposed on the image receiving layer and bonded to the image receiving layer;
- a release material layer disposed on the lower surface of the inner core layer and bonded to the core layer;
- the bonding strength of the core layer to the image receiving layer and the laminate layer being greater than the bonding strength of the release material layer to the core layer;
- and,
- wherein, attempted delamination of the document results in the scored pattern in the core layer being adhered to the image receiving and laminate layers to visually evidence tempering.
An identification document comprising:
- an inner core layer of material having upper and lower surfaces;
- an image receiving layer disposed on at least one of the upper and lower surfaces of the inner core layer;
- the image receiving layer having one or more fixed or variable items of information thereon;
- the one or more fixed or variable information items including a ghost image;
- the ghost image being printed on the image receiving layer using a monochromatic ink jet ink;
- the ink jet ink including a dye which is soluable in solvents;
- and, wherein, attempted delamination of the document using solvents results in the ink forming the ghost image bleeding to evidence tampering of the document.
