Paper Abstract

A multiple-level technique suitable to obtain high efficient Optically Variable Device is presented. The target is the realization of a very complex holographic images with various kinetic and dynamic effects, of interest for the application in the security market. The technique, involving the use of a positive and a negative photoresist process, and its application for the fabrication of complex diffraction gratings are described.
