Abstract

Procédé de fabrication d'une structure à deux couches magnétiquement et visuellement détectable. Le procédé consiste à appliquer sur un support une première couche 21 comportant un liant contenant une matière colorée et à la laisser sécher puis à appliquer, sur cette première couche, une seconde couche 23 comportant un liant contenant une matière magnétique visuellement distincte de la matière colorée et dispersée avec le liant dans un solvant qui constitue un solvant partiel pour le liant de la première couche et à appliquer sélectivement (au moyen de la tête magnétique 25) un champ magnétique qui provoque la migration de la matière magnétique dans la première couche. Application à l'établissement de documents de sécurité.
