Beschreibung
Zusammenfassung:	An inkjet ink contains an aqueous medium and pigment particles dispersed in the aqueous medium. The pigment particles contain a pigment and a specific resin. The specific resin includes an acid group and a first repeating unit derived from a specific monomer, and has a crosslinking structure derived from a carbodiimide crosslinking agent. The specific resin has a neutralization rate of at least 20% and no greater than 50%. The first repeating unit has a percentage content in the specific resin of at least 1.0% by mass and no greater than 20.0% by mass. The specific monomer has a morpholine structure or a pyrrolidone structure.
