Abstract
Anti-falsification paper characterized in that thin fragments having brightness, which are obtained by fragmenting nacreous pigment coated paper coated with a nacreous pigment coating solution mainly comprising a nacreous pigment and a binder insoluble in cold water but soluble in hot water, are allowed to exist near the surface of a substrate sheet. Even when falsification is attempted by reproduction using a color copying machine, the colors of the thin fragments having brightness, which are mixed in paper, cannot be reproduced. Therefore, a genuine (original) can be easily distinguished from a forgery (copy). The thin fragments are firmly bonded to paper by the action of the binder, and fall-off of the thin fragments does not occur at the time of printing. Even when anti-falsification paper becomes spoilage or waste paper, thin fragment with brightness does not adversely affect recovery of the pulp.
