20110091665 | SECURITY ELEMENT HAVING A SCREENED LAYER COMPOSED OF GRID ELEMENTS - 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. | 04-21-2011 |

The area of each pixel is smaller than the area of the reflective areal region by at least one order of magnitude. Each pixel has at least one reflective facet which is formed in a surface of the carrier, and the at least one reflective facet reflects light incident along a predetermined direction on the areal region directionally in a reflection direction predefined by the orientation of the facet. The orientations of the facets of different pixels have a substantially random variation over the reflective areal region. | 12-20-2012 |
20130063826 | METHOD FOR PRODUCING A MICROSTRUCTURE ON A CARRIER - A method for producing a microstructure on a carrier by: (a) manufacturing a donor foil by forming an embossed structure with elevations and depressions in a first foil material and applying a transfer layer to the embossed structure, (b) manufacturing an acceptor foil by applying an adhesive layer to a second foil material, (c) laminating the donor foil and the acceptor foil by means of the adhesive layer, the transfer layer on the elevations of the embossed structure bonding to the adhesive layer, and (d) transferring the bonded regions of the transfer layer to the acceptor foil by separating the donor foil and the acceptor foil from each other, thereby forming in the acceptor foil a first microstructure from the transferred regions of the transfer layer, and/or forming in the donor foil a second microstructure complementary to the first microstructure. | 03-14-2013 |
