Title:

METHOD FOR PRODUCING A PROTECTIVE HOLOGRAM

Document Type and Number:

WIPO Patent Application WO/2002/103457

Kind Code:

A1

Abstract:

The invention relates to data carriers marking by means of protective holograms using a hologram property to modify the spatial position and the colour of a restored image when the orientation of said hologram is modified in relation to a light source. The inventive method consists in producing a required image, recording a hologram therefrom, producing a metallic matrix based on said hologram and in successively replicating the protective hologram along the surface of a polymeric film by embossing the matrix thereon. Prior to producing the matrix for replicating holographic images of the required image which consists of a range of holographic images, an operation for producing a common metallic matrix from each individual holographic image is carried out, thereby reconstructing the mirror image of the required image. The aim of the invention is to develop a technologically simplest method by creating conditions for a mechanical, and not optical, printing of individual holographic images which form the required image on the surface of a conductive polymer or a polymer layer provided with a conductive coating.
