<p>The present invention relates to an X-ray sensitized yarn, a method for manufacturing the same, and an anti-forgery product using the same. The X-ray sensitized yarn of the present invention is manufactured by containing an X-ray absorbing material in an external core type composite fiber which is designed such that the total specific gravity of the external core type composite fiber prepared by melt complex spinning is one or higher and an external fiber is made of a hydrophilic polymeric resin. According to the X-ray sensitized yarn of the present invention, depending on the specific design of the external core type composite fiber, the percentage of the X-ray sensitized yarn added to a paper raw material which is sunk at the time of a paper making process can be increased, and the X-ray sensitized yarn can be easily blended with the paper raw material due to high dispersibility of the external fiber in the external core type composite fiber. The anti-forgery product using the X-ray sensitized yarn of the present invention facilitates authenticity identification on an X-ray, and thus can be usefully applied for anti-forgery of bills, vouchers, securities, and passports, or for preventing imitation of expensive luxury.
