Publication number: 20230038961Abstract: A semi-finished product method with a liquid crystal security feature includes unrolling and transporting a continuous film in a transporting direction and providing on the film a liquid crystal layer containing a substance whose absorption of polarized light depends on its orientation. The method includes at least one of (A) arranging a lacquer layer on the film and embossing it for a first alignment structure, and at least partly covering it with the liquid crystal layer, the first alignment structure able to cause liquid crystal molecules of the liquid crystal layer to align only in a first direction in first regions and only in a second direction, in second regions, and (B) embossing the liquid crystal layer while the liquid crystal layer is uncured providing a second alignment structure to cause liquid crystal molecules to align only in a third direction in third regions and only in a fourth direction, in fourth regions.Type: ApplicationFiled: July 29, 2022Publication date: February 9, 2023Inventors: Carlos Carrasco, Beatriz Cerrolaza, Winfried Hoffmüller, Friedrich Kretschmar, Denise Schwab

Patent number: 11021001Abstract: The present invention is related to a manufacturing method of an optical feature for documental security which includes multiple latent images whose visualization depend on the mode the feature is observed. The method comprises the steps of defining the different regions present on the inner surface of a first confinement structure; inducing different alignment directions on the defined regions; defining a second alignment structure wherein the second structure is a polarizer with multiple patterns; placing the liquid crystal between the first and the second structures, and polymerizing the liquid crystal, forming a sheet. The images are visible by means of a polarized light source or a polarizing sheet.Type: GrantFiled: October 8, 2015Date of Patent: June 1, 2021Assignees: UNIVERSIDAD POLITECNICA DE MADRID, ALISE DEVICES, S.L.Inventors: Morten Andreas Geday, Patxi Xabier Quintana Arregui, Jose Manuel Otón Sánchez, Beatriz Cerrolaza Martínez, Carlos Carrasco Vela

Patent number: 10800202Abstract: The present invention relates to a production method and to a device for document security applications including various latent images on each side. The invention comprises: depositing, according to an established pattern, at least one layer of metallized material, forming a holographic element on at least one part of one of the surfaces of a confinement substrate; defining different regions on the surface of the substrate; inducing different alignment directions for orienting a liquid crystal according to the previously defined regions; doping the liquid crystal with at least one dichroic dye; placing the liquid crystal over at least one confinement substrate, covering the holographic element; adding a second confinement substrate, forming a sandwich-type structure; and polymerizing the liquid crystal, forming a sheet.Type: GrantFiled: July 10, 2015Date of Patent: October 13, 2020Assignees: UNIVERSIDAD POLITECNICA DE MADRID, ALISE DEVICES, S.L.Inventors: Patxi Xabier Quintana Arregui, Morten Andreas Geday, José Manuel Otón Sánchez, Beatriz Cerrolaza Martinez, Carlos Carrasco Vela

Patent number: 8885121Abstract: A novel document security and authentication system is based on a transparent element on which more than one image appears depending on the manner in which the element is viewed. The system is based on cells or sheets of liquid crystal doped with one or more dichroic dyes. The images obtained with the aid of a polarizer can be printed onto a very thin (?m or 10 tens of a ?m) sheet of polymer material; the images may also be in greyscale or in color. There is no need to apply electrical signals during the production or use thereof.Type: GrantFiled: November 12, 2010Date of Patent: November 11, 2014Assignee: Universidad Politecnica de MadridInventors: Xabier Quintana Arregui, Jose Manuel Oton Sanchez, Morten Andreas Geday, Carlos Carrasco Vela
