Abstract

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.
