    摘要： A data carrier having at least one optically variable element, at least one surface element, and at least one security element comprising at least part of the at least one optically variable element and at least part of the at least one surface element. The at least one surface element is configured to guide impinging electromagnetic radiation towards the at least one optically variable element. The data carrier is configured such, that electromagnetic radiation is impinging on the at least one surface element under at least a first arrival angle when the data carrier is seen under a first observation angle, and such, that electromagnetic radiation is impinging on the at least one surface element under at least a second arrival angle being different from the first arrival angle when the data carrier is seen under a second observation angle being different from the first observation angle. The at least one optically variable element is configured to reflect at least a first reflection spectrum upon impingement of the electromagnetic radiation being impinging on the at least one surface element under the first arrival angle, whereby the at least one security element appears according to at least a first appearance, and is further configured to reflect at least a second reflection spectrum upon impingement of the electromagnetic radiation being impinging on the at least one surface element under the second arrival angle, whereby the at least one security element appears according to at least a second appearance being different from the first appearance.

    摘要： Provided is a data carrier comprising a card body, wherein the card body is configured to interact with impinging electromagnetic radiation (R) such, that a laser marking (M1) having a first appearance (A1) is generated in the card body in the region of impingement. The data carrier further comprises at least one protection element that is configured to interact with impinging electromagnetic radiation (R) such, that a laser marking (M2) having a second appearance (A2) is generated in the card body, wherein said second appearance (A2) differs from the first appearance (A1).

    摘要： A see-through security element (2), a security document (1) and a method for producing a see-through security element (2). The see-through security element has a first element with one or more transparent first partial areas and at least one reflective second partial area. The see-through security element has a second element with one or more first partial areas, which in each case in transmission form a color filter matched to a respectively assigned color, and has at least one second partial area, which is formed colorless, in particular colorless transparent, or in transmission and/or reflection forms a color filter which is matched to a color which is not assigned to any of the one or more first partial area of the second element. The first partial areas of the first element and the first partial areas of the second element at least partially overlap.

    摘要： Composite cards formed include a security layer comprising a hologram or diffraction grating formed at, or in, the center, or core layer, of the card. The hologram may be formed by embossing a designated area of the core layer with a diffraction pattern and depositing a thin layer of metal on the embossed layer. Additional layers may be selectively and symmetrically attached to the top and bottom surfaces of the core layer. A laser may be used to remove selected portions of the metal formed on the embossed layer, at selected stages of forming the card, to impart a selected pattern or information to the holographic region. The cards may be ‘lasered’ when the cards being processed are attached to, and part of, a large sheet of material, whereby the “lasering” of all the cards on the sheet can be done at the same time and relatively inexpensively.
