<P>PROBLEM TO BE SOLVED: To provide an inkjet recording method which prevents an ink from penetrating and provides high character printing quality in a mixed color portion especially in a line printer during printing in recording on standard papers. <P>SOLUTION: The inkjet recording method performs printing on the standard papers by using inks of two or more colors containing at least color materials, organic solvents, and water. The content of water in each of the inks represents 10% or higher by mass and less than 50% by mass of a total ink mass. At least one kind of the organic solvents is a water soluble organic solvent having an SP value ((MPa)<SP>1/2</SP>) of 16.5 or higher and less than 24.6 and the content of the water soluble organic solvent having an SP value ((MPa)<SP>1/2</SP>) of 16.5 or higher and less than 24.6 is 30% or higher by mass of a total ink mass, and the lower the density of the color material in the ink, the earlier the ink is printed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
