<P>PROBLEM TO BE SOLVED: To provide an inkjet recording method that can suppress color change of a recording part in a secondary color under high-humidity environment even though a combination of water-based inks has a relatively large difference in migration levels. <P>SOLUTION: In the inkjet recording method, two or more types of the water-based ink for inkjet recording are overprinted and recorded in a recording medium. The water-based ink includes: a colorant; water; and a water-soluble organic solvent, in which two or more types of water-based ink are overprinted for satisfying one of conditions (I) and (II). The condition (I): in the two or more types of water-soluble ink to be overprinted, the water-soluble ink with the maximum migration level includes a cationic polymer. The condition (II): in the two or more types of water-soluble ink to be overprinted, the water-soluble ink which reaches the recording medium before or at the same time as the water-soluble ink with the maximum migration level includes a cationic polymer. <P>COPYRIGHT: (C)2013,JPO&INPIT |
