Aqueous ink for inkjet recording, ink set, inkjet recording device, and image forming method

An inkjet recording apparatus comprising:

• an ink storage section, an ink ejection unit, and an aqueous ink for inkjet recording stored in the ink storage section,
• wherein
• the ink ejection unit is configured to eject the aqueous ink for inkjet recording to form an image on a fabric, and
• the aqueous ink for inkjet recording comprises:
• a pigment, a binder, a crosslinking agent, and a wax particle, wherein
• the binder comprises an acrylic resin,
• the crosslinking agent comprises at least one selected from the group consisting of an oxazoline group-containing compound and a carbodiimide group-containing compound,
• a ratio of an amount of the crosslinking agent to a total amount of the binder, the crosslinking agent, and the wax particle is 0.05 or greater, and
• the wax particle forms aggregates when dropped into an aqueous calcium solution having a concentration of 0.05 wt %.

An image forming method for forming an image on a fabric by an inkjet recording method, comprising:

• a pretreatment step of applying a cationic pretreatment liquid to the fabric, wherein the pretreatment liquid is applied within an area where an image is to be formed using an aqueous ink for inkjet recording;
• an image forming step of forming an image on the pretreated fabric using the aqueous ink for inkjet recording;
• and
• a drying step of drying the aqueous ink for inkjet recording by heating the fabric on which the image has been formed,
• wherein the aqueous ink for inkjet recording comprises:
• a pigment, a binder, a crosslinking agent, and a wax particle, wherein
• the binder comprises an acrylic resin,
• the crosslinking agent comprises at least one selected from the group consisting of an oxazoline group-containing compound and a carbodiimide group-containing compound,
• a ratio of an amount of the crosslinking agent to a total amount of the binder, the crosslinking agent, and the wax particle is 0.05 or greater, and
• the wax particle forms aggregates when dropped into an aqueous calcium solution having a concentration of 0.05 wt %.
