Patent

CA 2424655

Described is a laminate body, in particular a laminate foil, comprising a laser-sensitive layer and an identification element, for example a diffraction and/or hologram structure, a reflection layer, a printed image or the like, which is provided in a second layer and/or in the laser-sensitive layer, wherein the laser-sensitive layer has a marking produced by laser action, which is positioned in accurate register relationship relative to the identification element In addition the subject of the invention is a method of enhancing the forgery-proof nature of such a laminate body in which the laminate body is irradiated by means of a laser so that produced in the laser-sensitive layer is a laser-induced marking positioned in accurate register relationship with the position of the identification element.

La présente invention concerne un corps multicouche, notamment un film multicouche, comprenant une couche sensible au laser (4, 40) et un élément d'identification, tel qu'une structure de diffraction et/ou d'hologramme (5b, 5c, 50b), une couche de réflexion (5r, 50r), une impression (5d) ou un élément similaire, qui est pourvu dans une seconde couche (5, 50) et/ou dans ladite couche sensible au laser (4, 40). Cette couche sensible au laser (4, 40) présente un marquage (10, 10x, 10y) produit par laser, qui est placé conformément au repérage par rapport à l'élément d'identification (5b, 5c, 50b). La présente invention concerne également un procédé permettant d'assurer une meilleure protection d'un tel corps multicouche contre des contrefaçons. Selon ce procédé, le corps multicouche est irradié au moyen d'un laser, de façon à produire dans la couche sensible au laser (4, 40) un marquage(10, 10x, 10y) produit par laser, qui est placé conformément au repérage par rapport à l'élément d'identification (5b, 5c, 50b).
