INFORMATION CARRIER WITH AN OPTICALLY VARIABLE STRUCTURE (VARIANT EMBODIMENTS)

摘要

The invention relates to information carriers with an optically variable structure. The information carrier comprises a coating which is in the form of a printed raster, and a three-dimensional raster. The three-dimensional raster is at least partially arranged on the coating. The width of the lines and distance between the lines of the printed and three-dimensional rasters and the mutual orientation of the rasters are selected so as to form a moiré image, and when the carrier is viewed at a direct angle to the surface, the coating is fully discernible while the moiré image is hidden. When the carrier is viewed at an acute angle, that part of the coating which is located on the surfaces of the three-dimensional raster, which surfaces are arranged parallel to the direction of observation or are shielded from the observer by elements of the three-dimensional raster, is not discernible. In this case, that part of the coating which is located on the surfaces of the three-dimensional raster, which surfaces face the observer and are not shielded from the observer by elements of the three-dimensional raster, is discernible, and, as a result thereof, the moiré image becomes visible. The two-colour border of the printed raster is primarily arranged on inclined sections of the three-dimensional raster. When the angle of inclination of the carrier is changed, the effect of movement of the borders of the coloured strips on the carrier is observed.
