Document Type and Number:
Japanese Patent JP2022103952
Kind Code:
A
Abstract:
To provide: an aqueous ink jet ink composition capable of achieving both a suitable optical density and high light fastness in a recording section formed with the aqueous ink jet ink composition, the aqueous ink jet ink composition being also excellent in the stability in discharge by an ink jet method and the clogging recovery of an ink jet nozzle; and a recording method based on the aqueous ink jet ink composition.SOLUTION: An aqueous ink jet ink composition of the present disclosure contains a color material represented by formula (1) in the figure, a water-soluble organic solvent, and water. The color material represented by formula (1) contains two or more kinds of alkali metal ions as counterions, and the counterions include at least a sodium ion.
