A PIGMENT HAVING A COLOR SHIFT, DEPENDING ON AN ANGLE OF VISION, A METHOD OF PRODUCING THE MENTIONED PIGMENTS, AN APPLICATION SHOULD BE RESPONSIBLE FOR AN INDIVIDUAL RESPONSE, IS RESISTANTLY RESISTANT, RESISTANTLY OPEN

摘要

The invention describes luminescent optically variable pigments (OVP), methods for obtaining such pigments, as well as the use of such pigments as security elements in inks, coatings and articles. The luminescence centers are preferably incorporated into the dielectric material of the OVP's opticaliFabry-Perot/i resonance cavity, allowing for the machine-discrimination of luminescent OVP from simple mixtures of luminescents and non-luminescent OVP.
