The secrets of the design of security holograms for marking products against counterfeiting and falsification hide in visual color effects. The use of plasmon diffraction gratings in the production of holograms creates color volumetric images, color microtext, color hidden image, horizontal and vertical flip-flop effects (colored and imaging). The review briefly presents the possibilities of creating new optical security elements and security holograms with unusual color effects based on plasmon diffraction gratings and three-dimensional holograms in a thick-layer photosensitive recording medium.
