PROBLEM TO BE SOLVED : To provide a recording medium 10 having so high security properties that a latent image 105 is printed by using ink containing a fluorescent rare earth complex and using an ink-jet system without using an ink ribbon on which traces such as private information are left.
SOLUTION : The recording medium 10 is obtained by laminating at least a receptive layer 21 and a protective layer 15 on one surface of a base material 11. The receptive layer 21 comprises at least a cationic urethane resin, a cationic fixing agent and a filler. The latent image 105 is formed on the receptive layer 21 by using the ink containing the fluorescent rare earth complex and using the ink-jet system. The receptive layer 21 comprises the cationic urethane resin, the cationic fixing agent and the filler and the latent image 105 is a color image.
