    • A method for interlaminating an embossed hologram, the embossed hologram comprising an optionally transparent 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 with the embossed side or embossed layer, comprising the steps of : a) conditioning the outermost surface of the layer of inorganic HRI- material with an alkaline solution or an acidic solution; 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 a layer of an adhesive composition to the conditioned outermost surface of the layer of inorganic HRI-material support; and d) laminating the outermost surface of the layer of HRI-material to a polymer film, 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. A laminate obtainable therewith, and a security document comprising the laminate are also disclosed.
