Abstract: A tamper-indicating printable sheet. A preferred embodiment of the invention provides a tamper-indicating printable sheet comprising a retroreflective layer comprising a plurality of microbeads partially embedded in an inkjet receptive beadbond layer; and a reflector layer between one of the microbeads and the inkjet receptive beadbond layer. The present invention provides a method of making a tamper-indicating printable sheet.

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: In one aspect, the invention provides a security laminate comprising a retroreflective layer comprising a plurality of retroreflective microbeads partially embedded in and protruding from a beadbond layer and having image receptive material disposed around the protruding microspheres. In another embodiment, the security laminate further comprises indicia patterns viewable in retroreflective light. In another embodiment, the security laminate is imaged on the image receptive material.

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.
