ABSTRACT:
An aqueous ink contains at least an aqueous medium, a surfactant, and a dye. The aqueous medium includes only water and at least one water-soluble organic compound(s) and the static surface tension of the aqueous medium is from 45 mN/m or more to 57 mN/m or less. The dynamic surface tension of the aqueous ink satisfies the following conditions: (1) The dynamic surface tension of the aqueous ink at a lifetime of 50 milliseconds is from 42 mN/m or more to less than 49 mN/m; (2) The dynamic surface tension of the aqueous ink at a lifetime of 500 milliseconds is from 28 mN/m or more to 38 mN/m or less; and (3) A difference between the dynamic surface tension of the aqueous ink at a lifetime of 50 milliseconds and the dynamic surface tension of the aqueous ink at a lifetime of 500 milliseconds is 7 mN/m or more.
