摘要: A security element with a substrate and at least one micro-image arrangement, as well as at least one focusing layer interacting with the micro-image arrangement having an arrangement of focusing elements, wherein the at least one micro-image arrangement comprises at least one relief structure, wherein the micro-image arrangement generates a visible optical effect when viewed through the focusing layer, wherein the at least one micro-image arrangement comprises at least one color-shifting layer arranged on the at least one relief structure with a color-shifting effect discernible through the focusing layer.

摘要: A security element for securities or security papers has an embossing with, in particular diffractive, embossed structures, wherein the embossed structures are at least partially coated with a partial, metallic layer forming a tessellated image. The embossed structures may be designed as achromatic embossed structures and may form a relief adapted to the tessellated image.

摘要: A security element for securities or security papers has at least one first region having first structures, which first structures reflect a first piece of information into different spatial regions, so that a movement image is created for a viewer with corresponding movement of a light source and/or a change in the viewing angle. When the light source and/or when the viewing angle is changed, a movement of the first piece of information is simultaneously created. The security element is thereby formed with at least one second region having second structures, which second structures reproduce a static and/or viewing angle-independent second piece of information. In addition, a process manufactures a security element.

摘要: A security element with increased protection against forgery includes at least one first region with structures that reflect an image motif in different spatial regions, such that a moving image is produced for an observer when a light source is moved correspondingly and/or when the viewing angle is changed. When the light source is moved and/or the viewing angle is changed, a movement of the image motif occurs at the same time. Furthermore, an optical effect layer is provided which defines a second region. The structures are covered by the optical effect layer over their entire surface or partially.
