DATA SUPPORT WITH AN OPTICALLY VARIABLE ELEMENT |
摘要 |
The invention relates to a data carrier with an optically variable structure having an embossed structure and a coating contrasting with the surface of the data carrier. The embossed structure and the coating are so combined that at least parts o f the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and obliqu e viewing. The coating is executed uniformly and the embossed structure is divided into partial areas where different partial embossed structures are provided. |
