<p><P>PROBLEM TO BE SOLVED: To provide a printed matter with a releasable opacifying layer in which secret information data can not be visually confirmed even under a strong light, and whose manufacturing cost is inexpensive, and in which an image of the opacifying layer of the outermost surface has sharp characteristics and the opacifying layer can be formed by an in-line processing by an offset printer, and which is constituted of the opacifying layer with a freedom in its design. <P>SOLUTION: The printed matter 1 with the releasable opacifying layer is prepared by applying a colorless highly adhesive anchor vanish layer 16 consisting of an image of the secret information data on a surface of a polypropylene film layer 18 and applying the deep-colored whole surface solid releasable opacifying layer 22 comprising a printing ink using a styrene-acrylic resin and a urethane resin as a binder. In the printed matter 1 with the releasable opacifying layer, the secret information data are formed of the releasable opacifying layer 22 on the highly adhesive anchor vanish layer 16 which is not releasable by pressing a pressure-sensitive adhesive tape thereon. <P>COPYRIGHT: (C)2003,JPO</p> |
