Abstract: A transparent tamper-indicating data sheet is provided wherein a transparent durable layer (a first major component), such as polyester or a multilayer optical film (MOF), is adhered to a fragile layer (a second major component), such as a holographic foil or a security laminate, such as Confirm™ Security Laminate, either the fragile sheet or film or the durable layer being printed with identification and/or verification information. The components of the transparent data sheet are laminated together with or without an adhesive layer between the two major components. The two major components have the same outside dimensions and are congruent. Evidence of tampering with the identification or verification information is easily viewed from either side of the transparent data sheet.

Abstract: A multilayer polymer film has an optical stack including a plurality of alternating polymer layers with skin layers having mechanical, optical, or chemical properties differing from those of the layers in the optical stack. In one embodiment, the multilayer polymeric film has one or more holograms that provide attractive and useful optical effects.

The components of the transparent data sheet are laminated together with or without an adhesive layer between the two major components, such that the printed information or image is sandwiched between the two films. The two major components have the same outside dimensions and are congruent.

Abstract: A security laminate comprising (1) a protective layer having a first and a second surface, (2) a pattern of low adhesion coating bonded to a portion of the second surface of the protective layer, (3) at least one emblem bonded to a portion of the low adhesion coating/protective layer composite, (4) an adhesive bonded to the emblem layer/low adhesion coating/protective layer composite, and (5) a primer is not included between the low adhesion coating and emblem layers; wherein the bond between the emblem and the protective layer and the bond between the adhesive layer and protective layer are the most tenacious bonds, and the bond between the low adhesion coating and the protective layer is the least tenacious, whereby the emblems and adhesive layers are damaged in the pattern of the low adhesion coating during delamination. Also, secured documents comprising such security laminates and a method for securing documents utilizing such security laminates.
