More Information
Summary:The invention relates to a visibly variable security element (12) for securing valuable objects, wherein a relief structure (22) and a two-layer color mirror (30) are arranged one over the other and,in interaction, produce a visually variable and colored appearance in reflection, wherein the two-layer color mirror (30) consists of a reflective metal layer (32) and an ultra-thin absorber layer (34), which is arranged on the metal layer (32) and consists of silicon, a silicon alloy, or SiOx with x < 1. 本发明涉及种用于为有价物品提供安全保障的光学可变的防伪元件(12)，其中，凸纹结构(22)和双层的有色镜面(30)相叠地布置，并且在共同作用下形成在反射中光学可变且有色的外观，其中，双层的有色镜面(30)由反射式金属层(32)和布置在该金属层(32)上的超薄吸收层(34)组成，所述超薄吸收层由硅、硅合金或者x＜1的SiO制成。
