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.

Abstract: A security laminate comprising a protective layer having first and second surfaces, an embossing layer bonded to at least a portion of the second surface of the protective layer, a reflective layer bonded to at least a portion of the embossed layer/protective layer composite, an adhesion enhancing layer bonded to a portion of the reflective layer/embossed layer/protective layer composite, an adhesive bonded to at least a portion of the adhesion enhancing layer/reflective layer/embossed layer/protective layer composite wherein the bond between the reflective layer and the adhesion enhancing layer and the bond between the adhesion enhancing layer and the adhesive are each more tenacious than the bond between the reflective layer and the embossed layer and further wherein the bond between the adhesive and the adhesion enhancing layer is more tenacious than the bond between the adhesive and the reflective layer.

Abstract: The invention provides a transparent multilayer film comprising a cover layer, a destructible or irreversibly deformable layer, respectively, a pattern of adhesion-regulating material between the cover layer and the damagable layer, and an adhesive layer for bonding with a substrate. The damagable layer has a thickness of at least 10 .mu.m. The following relationship applies to the cohesive strength as well as the adhesion between the layers:a and d>c>bwherebya is the adhesive strength between cover layer (1) and layer (3) in the areas where no adhesion-regulating material (2) is present,b is the adhesive strength between cover layer (1) and layer (3), in the areas where adhesion-regulating material (2) is present,c is the cohesive strength of layer (3), andd is the adhesive strength between layer (3) and adhesive layer (5).The invention also provides for the use of the transparent multilayer film for protection of data on documents, as well as its use as a tamper-proof label.

Abstract: A retroreflective security laminate, designed to be applied to the surface of a document over information thereon, providing dual levels of verification. The laminates have primary legends which are viewable under both ordinary diffuse lighting conditions and retroreflective viewing conditions and may also have retro-legends which are viewable only under retroreflective viewing conditions.

Abstract: A retroreflective security laminate, designed to be applied to the surface of a document over information thereon, and having a protective cover sheet comprising an abrasion-resistant outer layer and a support layer which is resistant to deformation under localized pressure. Also methods for making such laminates.
