(57) [Abstract] [Problem] It is possible to visually judge the authenticity, it is difficult to reproduce an image even in color copy, high security, high designability, it can be manufactured with existing equipment, and it is compatible with small lot production. Provide anti-counterfeiting paper and securities that are inexpensive and affordable. A release layer, a light diffraction layer, a high-brightness ink reflection layer, In a forgery prevention paper in which a transfer layer in which a thermal adhesive layer is sequentially laminated is provided on a base paper as a stripe, the high-brightness ink reflective layer is at least metal-deposited by surface treatment with an organic fatty acid, methylsilyl isocyanate, or a cellulose derivative. It contains film strips and is partially provided by a printing method, and is provided in synchronization with the pattern of the printing layer. Further, the high-brightness ink reflection layer is colored, and the transparent reflection layer or the transparent and / or transparent layer is formed. Alternatively, a printing layer made of opaque ink is provided. Also, the invention is characterized by securities using the forgery prevention paper. |
