Abstract: An optical disc for data storage includes a layer of color-shifting material. Light passing through the color-shifting layer will have a color determined by the various constructive and destructive interference of the various wavelengths after they have passed through the material, diffracted while passing through the material, and are reflected off of various portions of the material, resulting in a color change when the viewing angle is changed. Additionally, an optical variable device may be defined within the disc, and may include the color-shifting layer.

Abstract: A vehicular validation tab has an outer film provided with an outer surface and an inner surface. Adhesive enhancing tie coat means are secured to the inner surface in some, but not all portions thereof. A layer of adhesive is secured to an inner surface of the outer film with identifying information interposed therebetween. A strippable film may be secured over the adhesive which may be pressure-sensitive adhesive and a write-resistant material may be secured to the outer surface of the outer film. Portions of the inner surface of the outer film not having the tie coat are provided with a release material to provide for differential bonding of the identifying information. The tie coat and release coat portions facilitate destruction of portions of the identifying material when the outer film is separated from the adhesive.

Abstract: 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.

Abstract: An informational article having a separation control material disposed on a portion of the surface of the article and an information receiving layer overlying at least a portion of the separation control material and a portion of the surface. The information receiving layer is adapted to receive information thereon. A transparent tape is adhesively bonded to the information receiving layer containing the information. The transparent tape is more strongly adhered to the information receiving layer than the information receiving layer is adhered to the separation control material. In this way, removal of the transparent tape from the article removes both (i) the information receiving layer and (ii) the information overlying the separation control material from the remainder of the information receiving layer and the information. Because of this, evidence of tampering is easily, visually, detectable. An associated method is also disclosed.

Abstract: A method of protecting an informational article, on which variable information is inserted, from photocopy duplication and alteration. The method comprises providing an informational article substrate having a zone for inserting the variable information and a refractive image disposed within the zone. The variable information is inserted in the zone, and transparent tape is secured over the variable information. The transparent tape has a write-resistant exposed surface. The refractive image will resist photocopy duplication of the variable information article, and the write-resistant exposed surface will resist alteration of the inserted variable information.
