| 发明名称 | Security elements exhibiting a dynamic visual motion | ||
| 摘要 | 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. | ||
