    • The present invention is related to a security element comprising a pattern of at least three layers, wherein a first layer comprises a first material which is capable of interacting with a first electromagnetic radiation but does not interact with a second and third electromagnetic radiation, a second layer comprises a second material which is capable of interacting with said second electromagnetic radiation but does not interact with a first and third electromagnetic radiation, and a third layer comprising a third material which is capable of interacting with a third electromagnetic radiation but does not interact with a first and second electromagnetic radiation, wherein said pattern provides a visual motion effect when exposed to a sequential illumination with a light source capable of separately emitting at least said first, second and third electromagnetic radiation. The present invention is furthermore related to the security element, the use of the security element for the protection of a security document against fraud or illegal reproduction, to a method for manufacturing the security element or security document, and to a method for creating a visual motion effect by sequential illumination of the security element.
    • 本发明涉及一种包括至少三层图案的安全元件,其中第一层包括能够与第一电磁辐射相互作用但不与第二和第三电磁辐射相互作用的第一材料,第二层 层包括能够与所述第二电磁辐射相互作用但不与第一和第三电磁辐射相互作用的第二材料,以及包括第三材料的第三层,所述第三材料能够与第三电磁辐射相互作用但不与 第一和第二电磁辐射,其中当暴露于具有能够分别发射至少所述第一,第二和第三电磁辐射的光源的顺序照明时,所述图案提供视觉运动效果。 本发明还涉及安全元件,安全元件用于保护安全文件以防止欺诈或非法再现的用途,用于制造安全元件或安全文档的方法以及用于创建视觉的方法 通过连续照明安全元件的运动效果。
