Data medium with optically variable structure (versions) // 2440248
FIELD: physics.SUBSTANCE: invention relates to multilayer articles - data media with an optically variable structure. The data medium which characterises its authenticity has a coating in form of a printed bitmap, and three-dimensional bitmap. The three-dimensional bitmap lies relative to the coating such that it at least partially lies on the coating. The width of the lines and the distance between the lines of the printed and three-dimensional bitmaps and relative orientation of the bitmaps is selected such that they form a moire pattern; when the medium is viewed at right angles to the surface, the coating is completely distinguishable, and the moire pattern is hidden. When viewing at an acute angle, part of the coating lying on the surfaces of the three-dimensional bitmap, lying parallel to the direction of viewing or closed from the viewer by elements of the three-dimensional bitmap, is not distinguishable, but part of the coating lying on surfaces of the three-dimensional bitmap facing the viewer and not closed from the viewer by elements of the three dimensional bitmap, is distinguishable, as a result of which the moire pattern becomes visible, where the boundary of two colours of the printed bitmap mainly lies on inclined areas of the three-dimensional bitmap. The effect of movement of boundaries of colour bars on the medium is observed when the angle of inclination of the medium is changed.EFFECT: invention improves the protective feature with a moire effect by obtaining a dynamic effect which simplifies authentication of the medium by an unskilled user.13 cl, 11 dwg
