ABSTRACT This process produces light diffracting patterns, such as holograms, which may be incorporated into a printed doc- ument and which are visible in non-coherent light so that a person inspecting the document may readily determine whether the light diffracting pattern is present and thus whether the document is genuine. A laminated sheet material is prepared for receiving an embossment of the light interference pattern. The laminated sheet includes a support layer, a release coat, at least one layer of thin transparent material over the release coat, and a reflective layer less than 1,000 Angstrom units thick, bonded to the surface of the transparent layer farthest from the support layer. A die carrying the light interference pattern in relief is impressed into the reflective layer and the adjacent transparent layer to form an embossed light diffracting pattern. The laminated material then has its reflective layer covered with adhesive and pressed against a flexible substrate such as paper, with heat and pressure. The reflective layer adheres to the sub- strate and the support layer separates from the transparent material by melting of the release coat.
