<P>PROBLEM TO BE SOLVED: To provide a regenerable information holding body, a printing label layer of which can be easily removed without being left on a base material, its regenerating method, and its regenerating device. <P>SOLUTION: A card 10A is formed by pasting a bonding label 16 serving as a signature column on a base material 12 serving as an IC card. A water swelling layer 14 is provided between the bonding label 16 and the base material 12. The water swelling layer 14 is fixed through an intermediate bonding layer 19 onto the base material 12. By giving the water to the bonding label 16, the water swelling layer 14 swells and the bonding force of the bonding label 16 becomes weak, resulting in allowing to realize the easy separation of the bonding label. By pasting a bonding label anew to the water swelling layer after being separated, a card 10A is regenerated. <P>COPYRIGHT: (C)2003,JPO |
