INKJET INK, INK CARTRIDGE, AND INKJET RECORDING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inkjet ink in which the generation of discharge kink can be controlled to satisfy a high level discharge property not existing in a conventional one, in an ink containing C. I. pigment violet 23; and to provide an ink cartridge and an inkjet recording method using the ink.

SOLUTION: The inkjet ink includes the C. I. pigment violet 23 made by being dispersed in a resin having an anionic group, and is characterized by including: polyoxyethylene alkyl ether in which the HLB value obtained by a Griffin method is at least 15.0, and which has a hydrophobic group having a carbon-carbon double bond; a polycarboxylic acid salt having a hydroxy group and at least three carboxy groups.
