20120170124 | Thin-Layer Element Having an Interference Layer Structure - The present invention relates to a thin-film element ( | 07-05-2012 |
20120228860 | SECURITY ELEMENT HAVING A MICROSTRUCTURE - The invention relates to a security element for security papers, value documents and the like with at least one microstructure which has a visual appearance that is viewing angle-dependent in transmission, whereby the at least one microstructure is formed from an arrangement of a multiplicity of structure elements with a characteristic structure spacing of 1 μm or more. According to the invention it is provided that the security element contains at least one motif image which, through the viewing angle-dependent visual appearance of the microstructure, is visible in transmission from certain viewing angles, and invisible in transmission from other viewing angles, and that the microstructure and the motif image together have a thickness of 50 μm or less. | 09-13-2012 |
20120319395 | SECURITY ELEMENT, VALUE DOCUMENT COMPRISING SUCH A SECURITY ELEMENT AND METHOD FOR PRODUCING SUCH A SECURITY ELEMENT - A security element for a security paper, value document or the like, having a carrier which has a reflective areal region which is divided into a multiplicity of reflective pixels. 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 |
20130093172 | SECURITY ELEMENT, VALUE DOCUMENT COMPRISING SUCH A SECURITY ELEMENT, AND METHOD FOR PRODUCING SUCH A SECURITY ELEMENT - A security element ( | 04-18-2013 |
20130099474 | SECURITY ELEMENT AS WELL AS VALUE DOCUMENT HAVING SUCH A SECURITY ELEMENT - A security element for a security paper, value document or the like, having a carrier which has a motif region that includes a visually perceptible motif with a first and a second motif part, wherein the motif region includes a first micro-optic representation arrangement which presents at least two different images in viewing angle-dependent fashion as a first motif part, and a second micro-optic representation arrangement which presents a reflective surface as a second motif part, which surface appears bulged relative to the actual macroscopic spatial form of the second micro-optic representation arrangement. | 04-25-2013 |
20130193679 | OPTICALLY VARIABLE SECURITY ELEMENT WITH TILT IMAGE - (EN) The invention relates to an optically variable security element ( | 08-01-2013 |
20130270813 | MICRO-OPTIC VIEWING ARRANGEMENT - A micro-optical inspection arrangement comprises micro-focusing elements which are composite bodies consisting of a main part and an additional part and which have a reference focal length. The main parts are provided as micro-focusing element preforms, and the additional parts are formed from one or more functional coatings. The invention also relates to a method for producing such a micro-optical inspection arrangement and to a micro-optical displaying arrangement comprising the micro-optical inspection arrangement according to the invention and a microstructure arrangement, in particular a moiré magnification arrangement and a modulo magnification arrangement. The invention also relates to security elements and data carriers that have the micro-optical inspection arrangement according to the invention. | 10-17-2013 |
20140238628 | Method for Manufacturing a Security Paper and Microlens Thread - A method for manufacturing a security paper includes an endless microlens thread having a top and an opposing bottom with the top provided at least in fractional regions with microlenses. A paper web having a predetermined ridge pattern is produced and defines ridge regions in which the microlens is embedded in the interior of the paper, and that exhibits, lying between the ridge regions, window regions in which the microlens thread emerges at the surface of the paper web. The microlens thread is introduced into the paper web and, at the same time, is joined on its bottom and, in the ridge regions, also on its top with the paper web. The paper web with the microlens thread forms the security paper. | 08-28-2014 |
