A concealed area is formed by a concealment ink layer on a surface on the polyolefin-based resin layer side of the base film layer. Moreover, a pattern printing layer is formed in order. The print information layer registered to the concealed area and formed by an inkjet system is formed on a surface on the heat adhesive resin layer side of the intermediate layer. The print information of the print information layer is visualized only from the heat adhesive resin layer side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
