Abstract
(EN)
The invention relates to the field of the protection of security documents such as for example banknotes and identity documents against counterfeit and illegal reproduction. In particular, the invention relates to a method for freezing the orientation of orientable magnetic or magnetizable pigment particles by irradiation hardening the coating layer comprising the orientable magnetic or magnetizable pigment particles through the substrate carrying the coating layer.
(FR)
L'invention se rapporte au domaine de la protection de documents de sécurité tels que, par exemple, des billets de banque et des pièces d'identité, contre la contrefaçon et la reproduction illégale. En particulier, l'invention se rapporte à un procédé permettant d'immobiliser l'orientation de particules de pigment magnétiques ou magnétisables orientables, en durcissant par irradiation la couche de revêtement comprenant les particules de pigment magnétiques ou magnétisables orientables, à travers le substrat supportant la couche de revêtement.
