MULTILAYER OBJECT HAVING THREE-DIMENSIONAL HOLOGRAM Russian patent published in 2011 - IPC G03H1/28 B42D15/10 

Abstract RU 2438155 C2

FIELD: physics.

SUBSTANCE: method of making multilayer object having a three-dimensional hologram involves using a template which is brought into contact with a photosensitive layer of the multilayer object, exposure to a coherent light beam and fixing the three-dimensional hologram by hardening the photosensitive layer. The template has alternating regions with at least two different surface structures containing at least two different graphic information elements, wherein one of the surface structures has an asymmetric relief structure or a kinoform structure. The surface structures of the template which do not contain graphic information have the form of an antireflective structure based on micro-relief technology and/or the form of a mirror and/or the form of a dull structure and/or the form of a scattering array.

EFFECT: making a three-dimensional hologram which enables to reproduce two or more separate graphic information elements.
