<P>PROBLEM TO BE SOLVED: To provide a card which can display variable information such as personal information and is highly secure with a high counterfeit prevention effect in media represented by cards. <P>SOLUTION: The card 1 includes on its substrate 2 an inkjet ink receiving layer 3. The receiving layer 3 contains two or more types of light emission materials that emit light by UV irradiation. The light emission materials emit light by UV irradiation of respectively different wavelengths, and characteristically, the emitted light beams differ in color. As the card has the receiving layer 3 on the substrate, print failure by inkjet printing such as bleeding is not caused, and clear inkjet print is enabled. Furthermore, when the receiving layer 3 of the card is irradiated with UV rays of different wavelengths, there is difference in emitted colors due to the difference in wavelengths, thereby achieving very high counterfeit prevention effects. <P>COPYRIGHT: (C)2013,JPO&INPIT |
