Patent ID: 8551387

Claim:
A process for recording a predetermined identification image and an electromagnetic signature on a secure personalized laser markable laminated RF identification document comprising: a. providing a laminated identification document having a plurality of laminate layers, comprising: a compatibilising layer, and an adjoining laminate layer bonded on each surface of the compatibilising layer at least one of which is an image receiving laminate layer, the compatibilising 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; b. laser marking the identification document with laser radiation at power densities less than about 1 watt/micron to thereby form the predetermined identification image and an antennae on the image receiving laminate layer with an electromagnetic signature which is RF readable.
