发明名称 Tamper resistant vehicular validation tab and associated method
摘要 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. The bond between the outer film tie coat portions and the adhesive is stronger than the bond between the adhesive and the license plate or other substrate, and the bond between the release coat portions and the adhesive is less than the bond between the adhesive and the license plate or other substrate. As a result, an effort to remove the vehicular validation tab will result in fracturing of the identifying material. The outer film is preferably transparent to facilitate viewing of the identifying material. The adhesive layer is also preferably transparent. In another embodiment the tab is securable to the inside of the window by an adhesive upper layer so as to be viewable therethrough.
