The present invention is directed toward a tamper evident informational article such as a temporary vehicle registration which may be made of paper or paperboard. The informational article has a zone for inserting information and a pattern within said zone which will resist effective counterfeiting. A transparent tape which preferably has a silicone resin coating which contains a wax is adhesively secured over information contained within the zone. In other embodiments, an alteration resistant article contains variable data and includes an outer film having an upper surface and a lower surface with an adhesive secured to the lower surface. A hologram for receiving at least a portion of the variable data on the upper surface is secured to the outer film lower surface and, in one embodiment, the hologram has portions which have release properties and portions which have greater adhesive bonding properties than the release containing portions. These respective portions may be established by providing a release material on certain portions of the upper surface of the hologram and providing adhesive enhancing materials on other portions of the hologram upper surface. The hologram may be embossed and have a metallized upper surface. A plurality of relatively small hologram particles may be provided in the outer layer and/or the adhesive layer. The hologram is secured to a substrate which, in one embodiment, has an upper surface printed with pattern means which are printed to a lesser depth than the variable data. In another embodiment, the hologram is provided as a unit with the outer film and overlies the variable data. Associated methods are provided. The invention may be employed in vehicle temporary registration permits, as well as in other uses. |

DETAILED DESCRIPTION The present invention has met the above-described need by providing a means for an informational article, such as a temporary license plate as supplied by the state, to inherently resist counterfeiting by photocopying and also further means to resist any alteration of the information inserted by the vehicle dealer.
The informational article has a preprinted side containing basic information, such as the state in which it is effective and a zone on such side for insertion of the expiration date by the dealer.
It is obvious that such temporary plates must be sufficiently large as to be viewable from a substantial distance such that a law enforcement officer, for example, could without getting out of his or her vehicle, quickly determine whether the temporary vehicle registration has expired.
The present invention provides a pattern within the zone which preferably is a refractive image, such as a hologram so as to resist reproduction by a form of photocopying.
Efforts to photocopy, even on paper of identical color as the original form would fail to reproduce the refractive image and thereby preclude photocopying as a means of counterfeiting the temporary registration plate.
Also, the invention contemplates the dealer after applying the date of expiration within the zone placing an adhesively bonded transparent tape which might be made of a polyester or polyolefin, for example, over that area.
The tape preferably is covered with a write-resistant coating which is preferably a silicone resin to which a wax, such as polytetrafluoroethylene, has been added.
The method of the present invention involves providing such an informational article, inserting the information within the zone with at least a portion of it being on the pattern to resist reproduction and thereafter applying the write-resistant protective tape thereover to adhesively bond the same.
In one embodiment of the present invention, an alteration resistant article containing variable data includes an outer film having an upper surface and a lower surface and adhesive means secured to the lower surface
