The present invention relates to a method for the replication of a patterned surface relief microstructure, comprising the steps of generation of a first layer with a patterned surface relief microstructure, generation of a master, by copying the microstructure of the first layer into a second layer, thereby involving at least one dry or wet etching step, characterized by an additional step, in which the microstructure of the master is brought into contact with a replica material, such that the microstructure of the master is reproduced in the replica. The invention further relates to the elements made as a replica according to the method. The surface relief microstructures are suitable to display images with a positive- negative and/or color image flip. The elements according to the invention are particularly useful for securing documents and articles against counterfeiting and falsification.

La présente invention se rapporte à un procédé permettant la réplication d'une microstructure à relief de surface à motifs, comprenant les étapes consistant à générer une première couche ayant une microstructure à relief de surface à motifs, en copiant la microstructure de la première couche dans une seconde couche, ce qui implique au moins une étape de gravure par voie sèche ou humide. Ledit procédé est caractérisé par une étape supplémentaire consistant à mettre la microstructure de l'original en contact avec un matériau de réplique de telle sorte que la microstructure de l'original soit reproduite dans la réplique. L'invention se rapporte en outre aux éléments utilisés en tant que réplique selon le procédé. Les microstructures à relief de surface conviennent pour afficher des images ayant une réflexion d'image positive, négative et/ou en couleur. Les éléments selon l'invention sont particulièrement utiles pour protéger des documents et des articles contre la contrefaçon et la falsification.
