AQUEOUS INK, INK EJECTION DEVICE, IMAGE RECORDING DEVICE, AND PRINTING METHOD

An aqueous ink includes water, a solvent group A having a vapor pressure of 0.07 Pa or more at 25° C., a thickener, and a binder polymer. The solvent group A is present in the aqueous ink in a weight percent of 31.0 wt % to 55.0 wt % with respect to a total amount of the aqueous ink. The thickener i...

More Information
Summary:An aqueous ink includes water, a solvent group A having a vapor pressure of 0.07 Pa or more at 25° C., a thickener, and a binder polymer. The solvent group A is present in the aqueous ink in a weight percent of 31.0 wt % to 55.0 wt % with respect to a total amount of the aqueous ink. The thickener is present in the aqueous ink in a weight percent of 13.0 wt % or less with respect to the total amount of the aqueous ink. The aqueous ink has a viscosity of 10 mPa·s to 14 mPa·s at 25° C.
