Abstract:
1. A method for interlaminating a transparent embossed hologram, said transparent embossed hologram comprising a support having two sides, at least one of the two sides either itself being embossed or having a layer thereon which is embossed and a layer of a HRI-material contiguous and coextensive with the embossed side or embossed layer, the method comprising the steps of: a) solvent conditioning the outermost surface of the layer of inorganic HRI-material with a solution consisting of at least one organic liquid; b) drying the outermost surface of the layer of the inorganic HRI-material thereby providing a conditioned outermost surface of the layer of inorganic HRI-material; c) applying an adhesive layer to the conditioned outermost surface; and d) laminating the outermost surface of inorganic HRI-material to an optionally transparent polymer film, wherein the at least one organic liquid is a solvent selected from the group consisting of ketones, ethers, heterocyclic ethers, lactams, amides, halo-aliphatic compounds, nitriles and esters; wherein at least one of the support and the polymer film is transparent; and wherein the HRI material is a material with a refractive index of at least 0.3 higher than that of the embossed material.
