  • Patent number: 9987875
    Abstract: (EN) The invention relates to an optically variable security element (20) for securing data carriers, having a flip image comprising first and second identifiers (24, 26) which can be detected from different first and second viewing directions (40, 42). According to the invention, the first and second identifiers (24, 26) of the flip image are present in an optically variable recording layer (30), which has a reflective layer (52) produced by a vacuum deposition process, and the security element (20) contains a viewing element screen (32) which is spaced apart from the recording layer (30) and which, when viewed from the first or second viewing direction (40, 42), reveals the first or second identifiers (24, 26), respectively.

  • Patent number: 9911074
    Abstract: The invention concerns a security element having a magnetic coding consisting of magnetic coding elements. At least one of the magnetic coding elements has a grid-shaped magnetic region which is formed by a plurality of mutually parallel grid strips made of magnetic material which respectively have a magnetic anisotropy. The grid strips lead, through their magnetic anisotropy, to the magnetization direction of the coding element being able to differ from the direction of the applied magnetic field. Since the resultant magnetic signals that the grid-shaped magnetic regions deliver cannot be simulated by conventional magnetic regions, said coding elements increase the anti-forgery security of the security element.

  • Patent number: 9557461
    Abstract: A two-dimensionally periodic, color-filtering grating has a contiguous high-refractive. In an embodiment, the color-filtering grating includes a metallic ground layer defining a grating plane and above the ground layer a two-dimensionally regular pattern of individual high-refractive, such as metallic areal elements that respectively extend parallel to the grating plane and respectively are spaced apart from the ground layer through an intermediate dielectric by a distance that is greater than the thickness of the ground layer and of the areal elements. The regular pattern has in at least two directions, which run parallel to the grating plane, a periodicity between 100 nm and 800 nm, and preferably between 200 nm and 500 nm.

  • Patent number: 9415622
    Abstract: The invention relates to a security element of at least one thin layer element in form of a multi-layer composition, capable of interference. The multi-layer composition, capable of interference, consists of at least one reflecting layer, at least one partially transmitting layer and at least one dielectric layer arranged between these layers. According to the invention the security element comprises in a first region a multitude of gaps in the reflecting layer and in a second region at least one gap or a multitude of gaps in the partially transmitting layer. Herein the second region is arranged at least partially within the first region and the total area of the second region, which is at least partially arranged within the first region, is smaller than the total area of the first region. Therefore the security element displays, when viewed from the partially transmitting layer, a different appearance in top view than in transmission view.

  • Patent number: 9336640
    Abstract: The invention relates to a security element for securing documents of value. Along the security element a portion of a magnetic coding with first and second coding elements is arranged. The coding elements are arranged along a predetermined direction, wherein the first coding element continuously has along the predetermined direction a first magnetic region with a first coercive field strength and the second coding element has at least one first gap region and one second magnetic region with a second coercive field strength. At least one of the first magnetic regions is directly adjacent to at least one of the second magnetic regions. The sum of the lengths of the directly adjacent first and second magnetic regions amounts to a maximum of 8 mm.

  • Patent number: 9308774
    Abstract: The present invention relates to a security element composed of at least one light-transmitting substrate on which a substantially opaque, screened layer composed of grid elements is located. According to the present invention, within the substantially opaque, screened layer composed of grid elements, at least one thin, solid, substantially opaque line is arranged that exhibits the form of at least one alphanumeric character, a graphic or a pattern. Such lines have line widths of at least 0.1 mm to 5 mm, preferably of 0.2 mm to 0.7 mm, particularly preferably of about 0.5 mm. Instead of lines, also extensive regions without any gap may be used, such that the alphanumeric character, pattern or graphic formed is perceptible only in transmitted light, but not in reflected light. The security element thus displays, at least when viewed from the side of the substantially opaque, screened layer, in top view, a different appearance than when looked through.

  • Patent number: 9248689
    Abstract: The present invention relates to a method for producing a security element (1), to a security element (1) obtainable by the method according to the invention, to transfer materials having the security elements according to the invention, and to objects of value secured with the security elements according to the invention. The security element (1) according to the invention has two functional layers (12, 22) which are bonded together by means of a resist layer (30). The resist layer (30) has a pattern which is employed to generate a congruent pattern in the first functional layer (12). Then the pattern of the resist layer (30), and thus also of the first functional layer (12), is exactly reproduced in the second functional layer (22). This is achieved by bonding the second functional layer (22) in the form of the pattern of the resist layer (30). The non-bonded areas of the second functional layer (22) are removed, thereby forming negative writing.

  • Patent number: 9243366
    Abstract: A method includes manufacturing a sheet-type substrate having a security thread in which a security thread having features spaced apart from one another in the longitudinal direction of the security thread is inserted into the substrate in such a way that it is at least partially embedded in the substrate. At least one of the features is displayed as an image after the embedding of the security thread. The stretch of the embedded security thread in the longitudinal direction is calculated based on the image of the at least one feature, and the region of the substrate in which the calculated stretch of the security thread exceeds a specified maximum stretch is obliterated depending on the calculated stretch.
