Abstract

L'invention concerne une structure et un procédé de fabrication d'éléments de protection destinés à protéger contre la contrefaçon des documents de valeurs comme des billets de banque, des documents d'identité, des chèques, des cartes de crédits et autres. L'élément de protection pour documents de valeur se présente sous forme d'une couche d'une pellicule transparente et d'une couche d'un matériau métallique comportant une section sur laquelle est formé un hologramme qui consiste en un microrelief comprenant des protubérances et des gorges alternantes. L'hologramme dans la section de la couche de matériau métallique se compose de fragments faits de différents matériaux métalliques ayant des couleurs différentes, et les sections adjacentes à l'hologramme sont transparentes. Le procédé consiste à recouvrir un fragment d'hologramme d'un masque de protection, à traiter la surface du matériau métallique à l'aide d'un réactif chimique, à le laisser reposer jusqu'à ce que la couleur du fragment de l'hologramme change librement par rapport au masque de protection, et à éliminer le masque de manière à obtenir ainsi un élément de protection comportant une image d'hologramme bicolore. L'invention permet d'accroître la protection contre les contrefaçons et les reproductions non autorisées de documents de valeur comportant cet élément de protection du fait de la formation d'un hologramme possédant une gamme de couleurs complexe.
