    • The invention relates to an optically variable element having a planar motif region (3) having a first motif (4), which contains a plurality of substructures (8) extending over the entire first motif (4) and each having bright and dark partial regions arranged alternately, wherein each substructure (8), upon variation of a first viewing angle (ax) - lying in a first plane - relative to a predetermined illumination direction (P1), is visible only at exactly one of the first viewing angles (ax) and all of the first viewing angles (ax) are different, with the result that the first motif (4) with the corresponding substructure (8) is perceptible in a manner dependent on the first viewing angle (ax).

    • The invention relates to an optically variable security element (12) for protecting valuable objects, said element comprising a substrate (28) with opposing first and second main surfaces and an optically variable structure (20) which is arranged on the first main surface and which has an embossed structure (22) and a coating (24). According to the invention: the coating (24) comprises at least one line pattern (30) and a background layer (26) that contrasts with the line pattern (30); the embossed structure (22) comprises a two-dimensional pattern of raised and/or recessed embossed elements (34); the coating (24) and the embossed structure (22) are combined such that at least one line segment (36) of a line (32) in the line pattern (30) lies substantially on each embossed element (34); and at least one of the parameters 'position of the line segment on the embossed element', 'orientation of the line segment on the embossed element' and 'form of the line segment' varies locally over the extent of the optically variable structure (20), such that when the security element (12) is tilted, the line pattern (30) creates the effect of motion, in particular a pumping or rotational effect.
    • 本发明涉及一种用于固定贵重物品,其包括基材的光学可变防伪元件(12)(28)具有相对的第一和第二主表面,并且布置在具有浮雕结构(22)的光学可变结构(20)的第一主表面和涂层 (24)。 根据本发明,它提供的是,涂层(24)包括至少一个印刷的线网格(30)和所述线网屏(30)对比的背景层(26),所述压花结构(22)在上升和/或凹陷的压花元件的二维网格(34) 包括将所述涂层(24)和压花结构(22)相结合,使得基本上每个压花元件(34)的线网格(30)的线(32)中的至少一个线段(36),并在参数中的至少一个 压花元素“压花元件上的线段的取向”和该线段上的位置“构成的线段”上的光学可变结构(20)的延伸部变化取决于位置,使得通过线网格(30)在所述安全元件的倾斜(12) 运动的影响,尤其是泵或旋转的效果。
