  • Publication number: 20050057036
    Abstract: The present invention relates to a security document and/or value document, in particular banknote, with security features and with a verification element for verifying the security feature.

  • Patent number: 6234537
    Abstract: A security document with optically excitable dyes for authenticity checking. Dyes are applied to or embedded in the security documents. The dyes are advantageously embedded in a carrier material which in conjunction with the dyes forms a laser-active element. Certain optically excitable dyes are incorporated in a security document in such a way that when the security and/or sensitive document is optically excited, the dyes embedded in the security and/or sensitive document resonate with the material of the securities and secure documents, so that a well-defined narrow spectrum of all excited materials is emitted.
