Abstract
Provided is an aqueous inkjet ink with which sufficient setting properties and image fastness are achieved even in printing on a less-ink-absorbent or non-ink-absorbent recording medium. An aqueous ink composition for use in an inkjet recording method includes a color material, an aqueous medium, a binder resin, and a wax. The binder resin includes an acid-modified polypropylene resin. The wax includes an oxidized polyethylene wax.

An aqueous ink composition for use in an inkjet recording method, the aqueous ink composition comprising:
- a color material;
- an aqueous medium;
- a binder resin;
- a surfactant;
- and
- a wax, wherein
- the binder resin includes an acid-modified polypropylene resin, and
