FIELD: printing industry.
SUBSTANCE: microoptical film structure comprises one or more planar systems of focusing elements and one or more planar systems of primary graphic pictograms, every of which is arranged in the focal plane of the focusing elements. The planar systems are configured so that one or more first optical images are formed with the help of the film structure. One or more secondary graphic pictograms are imposed onto or are formed on the focusing elements and/or primary graphic pictograms so that each secondary graphic pictogram is located outside the focal plane of the focusing elements, and at the same time one or more secondary graphic pictograms develop as static images. The first static images are visually strengthened or suppressed with one or more static images as a result of their mutual spatial location.
EFFECT: increased efficiency of protection.
