Document Type and Number:
Japanese Patent JP2009505155
Kind Code:
A
Abstract:
A toner for printing documents that are difficult to chemically or physically forge and that are readily easy to visually verify and methods of using and forming the toner are disclosed. The toner includes a colorant for printing an image on a surface of a document and a dye for forming a latent version of the image underneath a surface of a substrate. An image formed using the toner of the invention is readily verified by comparing the colorant-formed image and the dye-formed image. In addition, if a solvent is used in an attempt to alter the printed image on the substrate, the dye migrates or diffuses to indicate tampering with the document.
