Abstract:
An aqueous ink jet ink composition is for use in an ink jet recording method. The method includes ejecting ink from an ink jet head including nozzles. The nozzles are configured such that a shape of a side wall surface is a scalloped shape in which a scallop width S1 and a notch depth S2 satisfy S1/S2≥4. The aqueous ink jet ink composition includes a pigment and a solvent that contains a specific compound.
