Claims20
An inkjet printing method comprising the step of:
- ejecting a heated aqueous ink from a printing head so as to print an image on a printing medium,
- wherein the aqueous ink comprises silver particles having a particle size of 60 nm or less at a cumulative volume of 90%,
- wherein the aqueous ink comprises a first water-soluble organic solvent having a boiling temperature of 180° C. or higher, and
- wherein a mass ratio of a content (% by mass) of the first water-soluble organic solvent to a content (% by mass) of the silver particles is 2.5 times or more.
