<P>PROBLEM TO BE SOLVED: To provide an inkjet ink which yields a printed recording material excellent in curling characteristics, forms a stable image which is excellent in image quality and prevents transfer of a coloring material even when overwritten with a marker and offers a uniform gloss when printed on a glossy paper. <P>SOLUTION: The inkjet ink contains at least water, water-soluble organic solvents and a pigment, wherein water accounts for 10 mass% or larger but smaller than 50 mass% of the entire ink. Among the water-soluble organic solvents, a water-soluble organic solvent having an SP value of 16.5 or larger but smaller than 24.6 accounts for ≥30 mass% of the entire ink. The pigment is dispersed in the ink by an alkali-soluble polymer dispersant that is neutralized with an organic base. <P>COPYRIGHT: (C)2007,JPO&INPIT |
