    • A data carrier with an optically variable structure having an embossed structure with raised areas and a first coating contrasting with the surface of the data carrier. The embossed structure and the first coating are so combined that at least parts of the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and oblique viewing. The first coating is provided only in certain areas. Additionally, the optically variable structure has at least in partial areas a second coating likewise contrasting with the data carrier surface and disposed in overlap with the first coating at least in partial areas.
    • 具有光学可变结构的数据载体,具有凸起区域的压纹结构和与数据载体表面对比的第一涂层。 压花结构和第一涂层组合使得至少部分涂层在垂直观察时是完全可见的,但在倾斜观察时隐藏,使得在交替垂直和倾斜观察时产生倾斜效应。 第一涂层仅在某些区域提供。 另外,光学可变结构至少在部分区域中具有与数据载体表面对比的第二涂层,并且至少在部分区域中与第一涂层重叠设置。
