Abstract

Methods of creating tamper resistant informational articles and related products are disclosed. In one embodiment, a lens has a preformed transparent hologram, metallized portions are provided and may be altered through selective application of heat to predetermined parts thereof to create information which may be fixed or variable. Printing may be provided on the hologram before metallizing. A base portion underlies the metallized layer. In yet another embodiment of the invention, an opaque base portion has a hologram formed in the upper surface thereof with portions of the hologram being made readily visible by partial metallization covering only portions of the hologram with or without information provided as by printing overlying or underlying portions of the metallized sector or both. A transparent overlying lens is secured in overlying relationship. Metallizing may be such as to permit viewing underlying hologram portions or information or not. A corresponding method is provided.

Claims

1. A method of creating a tamper-resistant informational article comprising

providing an opaque resinous base member having a lower surface and an upper surface,

creating a hologram in the upper surface of said base member,

partially metallizing said upper surface, and

permanently securing a transparent lens overlying said base member upper surface.

2. The method of creating a tamper-resistant informational article of claim 1 including

creating a plurality of partially metallized portions within said partially metallized layer.

3. The method of creating a tamper-resistant informational article of claim 2 including

creating information at least partially overlying said partially metallized portions.

4. The method of creating a tamper-resistant informational article of claim 2 including

providing information at least partially underlying said partially metallized portions.

5. The method of creating a tamper-resistant informational article of claim 2 including

providing at least some of said partially metallized portions with portions of said hologram visible therethrough.

6. The method of creating a tamper-resistant informational article of claim 4 including

providing said underlying information such that it will be visible through said partially metallized portions.

7. The method of creating a tamper-resistant informational article of claim 1 including

creating said informational article as a card.

8. The method of creating a tamper-resistant informational article of claim 1 including

creating information between said opaque base member upper surface and said transparent lens.

9. The method of creating a tamper-resistant informational article of claim 8 including

creating said information with both fixed information and variable information.

10. The method of creating a tamper-resistant informational article of claim 3 including

creating said information at least partially underlying said partially metallized portions.

11. The method of creating a tamper-resistant informational article of claim 1 including

providing a photograph within and overlying a said partially metallized zone which in turn overlies a hologram.

12. The method of creating a tamper-resistant informational article of claim 4 including

creating said partially metallized portions such that underlying holograms or information can be viewed therethrough.

13. The method of creating a tamper-resistant informational article of claim 3 including

providing said information by printing.
