Abstract

Laminated documents such as I.D. cards using a phosphorescent material as a verification or validation pattern.

Claims

1. A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material having an adherent capability and a verification pattern of phosphorescent material integrated with said sheet material or said adherent capability.

2. A laminar assembly of claim 1 where said pattern is coated on said adherent capability.

3. A laminar assembly of claim 1 where said pattern comprises a phosphorescent zinc sulfide.

4. A laminar assembly of claim 1 where said phosphorescent material is dispersed in said plastic sheet material.

5. A laminar assembly of claim 1 where said plastic sheet material having said adherent capability comprises the front sheet member of an envelope comprising front and back sheet members having approximately the same dimensions and where said front sheet member is adapted to lamination to said information-bearing document.

6. A laminar assembly of claim 1 where said adherent capability comprises a layer of adhesive carried by said plastic sheet material.

7. A laminar assembly of claim 6 where said pattern is positioned between said plastic sheet material and said layer of adhesive.

8. A laminar assembly of claim 6 where said pattern is coated on said adhesive layer.

9. A laminar assembly of claim 8 where said pattern comprises said phosporescent material in a binder material which is water swellable.

10. A laminar assembly of claim 8 where said pattern comprises said phosphorescent material in a binder material which is water soluble.

11. A protective laminar assembly for lamination to an information-bearing document, said assembly comprising a plastic sheet material carrying a layer of adhesive and a pattern comprising a phosphorescent material coated on said adhesive layer said pattern comprising said phosphorescent material in a binder material which is water swellable or water soluble, said phosphorescent material having a particle size between about 2 to about 20 microns.

12. A laminar assembly of claim 11 where said plastic sheet material carrying said layer of adhesive and said light-transmissive pigment material coated on said adhesive layer comprises the front sheet member of an envelope comprising front and back sheet members having approximately the same dimensions and where said front sheet member is adapted to lamination to an information-bearing document.

13. A protective laminar assembly for lamination to an information-bearing document, said assembly comprising in order, a sheet of a cellulose triacetate having a hydrolyzed surface, an adhesive layer comprising a mixture of a low molecular weight polyvinyl acetate and a hydrolyzed polyvinyl alcohol coated on the hydrolyzed surface and a pattern of phosphorescent material having a particle size between about 2 to about 20 microns and comprising said phosphorescent material in a binder material which is water swellable or water soluble coated on said adhesive layer.

14. A protective laminar assembly for lamination to an information-bearing document, said assembly comprising in order, a polyester sheet material, an adhesive layer comprising an ethylene-ethyl acrylate copolymer, and a pattern of phosphorescent material having a particle size between about 2 to about 20 microns and comprising said phosphorescent material in a binder material which is water swellable or water soluble coated on said adhesive layer.

15. A protective laminar assembly for lamination to an information-bearing document, said assembly comprising, in order, a polyester sheet material, an adhesive system comprising a layer which comprises an ethylene-ethyl acrylate copolymer coated on the polyester sheet material and a layer of a mixture of a polyvinyl alcohol and a polyvinyl pyridine coated on the copolymer containing layer and a pattern of phosphorescent material having a particle size between about 2 to about 20 microns and comprising said phosphorescent material in a binder material which is water swellable or water soluble coated on the layer of the mixture.
