SYSTEMS AND METHODS FOR USING MICROSCOPIC CAPSULES CONTAINING ORIENTABLE MATERIALS FOR DOCUMENT SECURITY AND PROCESSING APPLICATIONS |
摘要 |
Systems and methods for using microscopic capsules containing orientable materials for document security and processing applications are presented. A security application comprising a medium having a substrate and a plurality of microcapsules is disclosed. The microcapsules contain magnetically orientable material and a liquid. The magnetically orientable material is oriented in a first alignment. Application of a magnetic field to the medium orients the magnetically orientable material to a second alignment, thereby altering the opacity of the medium. Magnetic material may also be dragged into a concentrated arrangement by a magnetic field, thereby altering the opacity of the medium. |
