Zusammenfassung:	Disclosed is security paper including a plurality of dyed security fibers having wavelength-dependent color changes embedded therein, in which each of the plurality of dyed security fibers is composed of fluorescent balls formed of a fluorescent substance producing a light-mission response at a predetermined wavelength, a security fiber containing the fluorescent balls, and a dyed layer formed on the outer surface of the security fiber using a material producing an light-mission response at a predetermined wavelength.
