The present invention is related to a coating composition for the production of a magnetically induced image, consisting of volatile components (S) and non-volatile components, the latter consisting of an ink vehicle (I) and magnetically orientable optically variable interference pigment (P), to a process for manufacturing the coating composition, and to the use of the composition for the production of a magnetically induced image coating on a substrate with the help of applied magnetic fields. Said magnetically induced image coating may be used as a security device on value- or identity documents, brand protection labels and the like.
La présente invention concerne une composition de revêtement pour la production d'une image magnétiquement induite, comprenant des composants volatils (S) et des composants non volatils, ces derniers consistant en un véhicule d'encre (I) et un pigment d'interférence optiquement variable magnétiquement orientable (P); un procédé de fabrication de la composition de revêtement; et l'utilisation de la composition pour la production d'un revêtement d'images induites magnétiquement sur un substrat à l'aide de champs magnétiques appliqués. Ledit revêtement d'images induites magnétiquement peut être utilisé comme dispositif de sécurité sur des documents de valeur ou d'identité, des étiquettes de protection de marques et similaires.
