Laminated identification document
First Claim
1. A secure personalized laser markable laminated RF identification document for recording a predetermined identification image and an electromagnetic signature thereon, the identification document comprising a compatibilising layer, bonded on each surface of the compatibilizing layer to an adjoining laminate layer, at least one of which is an image receiving laminate layer, the compatibilizing layer including on at least one surface an imaging material that can be laser marked with laser radiation at power densities less than about 1 watt/micron to form the predetermined identification image and maintain cohesive bonding with the adjoining laminate layers, wherein the adjoining image receiving laminate layer overlaying the surface that includes the imaging material is a conducting or a semiconducting material that is opaque or partially opaque, and is absorbent to the laser radiation and after exposure to the laser radiation the image receiving laminate layer becomes transparent and the laser radiation forms an antennae on the image receiving laminate layer with an electromagnetic signature which is RF readable.

Abstract
A laminated identification document having a plurality of laminate layers and an identification image thereon. The document has a core laminate layer having an upper surface and lower surface, at least one surface of which is printed with a dot matrix pattern and at least one visually opaque or reflective laminate layer bonded to and overlaying the printed surface. Upon pitting the laminate layer portions, the dot matrix pattern printed on the core laminate is expopsed to thereby form the identifying image.
A laser markable laminated identification document having a plurality of laminate layers wherein a compatibilizing layer is bonded to adjoining laminate layers, the compatibilizing layer includes an imaging material that can be laser marked.
A laminated identification document having a plurality of laminate layers and an identification image thereon, wherein at least one laminate layer is a compatibilizing layer.

6. A secure personalized laminated RF identification document for recording a predetermined identification image and electromagnetic signature thereon, comprising:
-
a core laminate layer having an upper surface and lower surface, at least one surface of which is printed with a dot matrix pattern wherein the dots have non-imaged are adjacent the dots, wherein the core laminate includes at least one compatibilizing layer bonded on each surface of the compatibilizing layer to an adjoining laminate layer, the compatibilizing layer including on at least one surface an imaging material that can be laser marked with the laser radiation at power densities less than about 1 watt/micron to form the identification indicia image while maintaining cohesive bonding with the adjoining laminate layers, wherein the adjoining laminate layer overlaying the surface including the imaging material is laser transparent to the laser radiation; and at least one visually opaque or reflective image receiving laminate layer that is a conducting or semiconducting material that can be pitted with laser radiation, bonded to and overlaying the at least one surface printed with the dot matrix pattern;
wherein upon pitting the image receiving laminate layer with the laser radiation, portions of the dot matrix pattern, printed on the core laminate are exposed to thereby form the predetermined identification image and the remaining land areas of the laminate form an antennae with an electromagnetic signature which is RF readable. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)
