A compound laminate containing a diffraction element which, for the purpose of rendering the falsification of a document, for example, more difficult, is glued to a substrate by means of an adhesive layer, using heat. The compound laminate includes a transparent stabilizing layer which uniformly distributes the heat, during the gluing process in the compound laminate, until the adhesive layer softens. Upon cooling, the adhesive layer forms a firm joint with the substrate. By means of an intermediate layer, the stabilizing layer is joined to a first layer of lacquer having engraved diffraction elements. A second layer of lacquer masks the diffraction elements and serves as a carrier for the adhesive layer. Tags in which the diffraction elements have a conspicuous, optically variable composition may be stamped or cut from the compound laminate. |
