PROBLEM TO BE SOLVED: To easily display the use time limit of a card or the like in an IC chip mounting body. SOLUTION: Second electrostatic antennas 12a and 12b are formed on a card base material 10 by a thermal transfer system, a 2-color thermosensitive recording layer is provided as a recording layer 16 and an IC chip mounting label 14 is joined onto the second electrostatic antennas 12a and 12b. The 2-color thermosensitive recording layer contains a black color developing leuco dye, a red color developing leuco dye, a developer and a sensitizer, polyvinyl alcohol is added further and UV setting OP varnish is printed by an offset printer on it and set. After performing segmentation in a card shape, when printing is performed to the thermosensitive recording layer 16 by using a thermosensitive printing testing device, red color is developed by low applied energy, black color is developed by high applied energy and printing quality is excellent. |
