<p>PROBLEM TO BE SOLVED: To prevent bright threads from separating from a base paper by a method wherein the bright threads are put in the base paper by paper making method under the condition that the glaring threads are intermittently exposed at bare parts are intermittently covered at covering parts between the bare parts. SOLUTION: Glaring threads 3 are put in a base paper 2 by paper making method so as to intermittently expose the threads 3 at bare parts and intermittently cover the threads 3 at covering parts 5 between the bare parts 4 so as to constitute an antifalsification paper 1. As a result, due to the intermittent exposure of the threads 3 at the base parts 4, when the paper is copied, no metallic color is represented, resulting in preventing the paper from being formed. At the same time, no confirmation of the edge face of the paper 1 is necessary for checking whether the paper is a forgery or not. Further, since the threads 3 are covered intermittently at the covering parts 5, no separation of the threads 3 from the base paper 2 develops. Furthermore, since both the ends of the threads are held in the base paper 2 by the covering parts 5, the separation of the threads 3 is surely prevented from developing.</p> |
