Abstract
An inkjet ink containing a colorant, where an amine compound is added as a pH adjuster. The ink is capable of preventing the pH of the ink from being shifted to the acidity side due to corrosive substances (e.g., acid substances) generated by deterioration of ink, adverse effects due to water absorption and moisture absorption, or degradation of resin (e.g., degradation of vinyl chloride-vinyl acetate copolymer resin), thus preventing erosion of a head nozzle member.
