Patent number: 10391807Abstract: In order to create novel security features in secure and/or valuable documents, a polymer layer composite, which has at least two polymer layers that are bonded to each other in a material fit is provided. At least one surface is printed with an absorbing printed layer within a visible region in and/or on the composite located on a polymer layer of the composite. The absorbing printed layer forms at least one printed region, and all printed regions of the printed surface of the polymer layer have a total surface area of at least 50% and not more than 95%.Type: GrantFiled: October 31, 2008Date of Patent: August 27, 2019Assignees: Bundesdruckerei GmbH, Bayer MaterialScience AGInventors: Oliver Muth, Manfred Paeschke, Arthur Mathea, André Leopold, Jörg Fischer, Malte Pflughoefft, Heinz Pudleiner
