摘要:
An inkjet recording ink is used for an inkjet recording device that includes a silicone rubber having a solubility parameter at 25°C of 6 to 8 as a member with which an ink comes in contact, the inkjet recording ink including water, a disperse dye, and an anionic surfactant, the content X (mass%) of the disperse dye and the content Y (mass%) of the anionic surfactant in the inkjet recording ink satisfying the relationship "Y/X≥0.7".
摘要:
An ink composition is held in an ink container that is provided with an ink inlet through which the ink container can be refilled with the ink composition, and is used in a state in which the ink container is fitted into an inkjet recording device that includes a recording head having a nozzle hole that ejects the ink composition, the ink composition including a disperse dye, and at least one of a silicon-based surfactant and a fluorine-based surfactant, the ink composition having a surface tension of 22 to 30 mN/m.
