<p>PROBLEM TO BE SOLVED: To provide a method for storing image information wherein entry of information, input of record or the like can be performed simply and easily, and the information and record is hard to imitate, while the entered information or stored record cannot be read with the naked eyes but can be read by specific means only, so that secrecy can be protected. SOLUTION: Image information is recorded on a base body having reflectivity by using a recording material comprising an infrared ray transmittable pigment (R-1), a pigment (A-1) having absorbing capacity in an infrared ray region, and a near infrared ray absorbing pigment (A-2), whereby it makes difficult to imitate information in a visible ray region, and at the same time information can be read in both of the visible ray region and near infrared ray region.</p> |
