Abstract: The present invention provides a method of forming a relief pattern as part of a layered structure and comprising, forming a relief pattern on the surface of a layer of the said structure and subsequently forming a protective fixing layer on at least part of the said relief pattern and serving to protect the underlying relief pattern during any subsequent processing of the said structure, and thereby also provides for a layered structure, generally comprising a substrate having a relief pattern formed on a surface of the substrate and wherein at least a portion of the said relief has been provided with a protective fixing layer serving to retain the characteristics of the relief pattern during any subsequent processing of the structure such as, for example, when forming a laminate structure with the relief pattern provided therein.

Abstract: The present invention provides for a device package comprising an element secured to a plastic body, the element having at least one opening into which material of the plastic body extends to at least assist with securing the element to the body.

Abstract: A metal identification platelet equipped with an identification code, while the identification code comprises a hologram. A method of producing the identification platelet with the identification code, including the following steps: A shield from an electro-insulation material is formed on a shim with a holographic motif. Then, the shim is galvanized in the places not covered by the shield from the electro-insulation material. And the completed metal identification platelets are removed from the shim.

Abstract: The present invention provides for a security article for anti-counterfeit (21, 31), authentication and/or tracking purposes, comprising a substrate material (25, 32) including at least one, but preferably several encoded metal holographic platelets, wherein each platelet (22, 33) carries a surface relief diffractive structure and can be authenticated by inspection of both a holo-graphic device by illumination and visual, eyeglass and magnifier inspection and which can also be authenticated by inspection under magnification of an aperture in the metal platelet carrying an authenticating code.
