Xerox Self-Erasing Paper
Thursday, May 22, 2008
Some documents are so secret you’ve got to keep them safe from even yourself, and that’s why Xerox invented self-erasing paper. The info fades away after 24 hours, so only your photographic memory can keep the info locked in. This is all due to a molecule that creates the print under ultraviolet light and then readjusts after 24 hours or under heat to make it disappear.
This paper is still under-going research at Xerox’s Palo Alto Research Center.
