Abstract
The invention pertains in a first aspect to a multilayer film that includes a frangible holographic image layer and an adhesive layer adjacent to a side of the holographic image layer; and, an additional temporary support layer that is adjacent a side of the holographic image layer that is opposite the adhesive layer, and provides integrity to the multilayer film. The additional temporary support layer can be a polyester film that is removable from the multilayer film at ≦10 gram per inch peel strength; or, can be a heat-shrinkable film that is removable from the multilayer film with the application of heat. After application of the multilayer film to a substrate, the holographic image layer forms an exterior surface of the multilayer film. In a second aspect, the invention pertains to an authentication label of the multilayer film for attachment to a substrate, wherein a side of the adhesive layer that is opposite the holographic image layer contacts the substrate, and the holographic image layer forms an exterior surface of the label.
