Abstract (en)
[origin: EP0486065A1] The invention relates to a security document having an integral security element, preferably an optically variable element in the form of hologram, diffraction or interference structures applied to the paper surface, and to a process for making such a security document. The security document is characterised in that the optically variable element is embedded in the security document, the paper surface forming one plane with the surface of the optically variable element.
