FIELD: physics.
SUBSTANCE: disclosed is a multilayer polymer material with a raster structure, having a transparent polymer layer with a micro-raster relief structure in form of spherical lenses and a superimposed transparent polymer layer with printed raster. The layer with printed raster lies at a distance from the surface of the lens raster close to the focal distance of its lenses. The material is made with micro-image raster with resolution of 10-20 mcm. Regions are selected in the field of the printed raster, said regions forming latent images, inside of which the orientation of the raster grid differs from the orientation of the raster grid outside said regions by an angle ranging from 1 to 20 degrees. The latent images become visible upon superimposing the printed raster with the lens raster to form different visual effects.
EFFECT: improved security of articles.
