Abstract
An inkjet ink set includes a first ink and a second ink. The first ink contains first pigment particles, a first binder, and a first aqueous medium. The second ink contains second pigment particles, a second binder, and a second aqueous medium. The first pigment particles each include a titanium pigment particle in a flat shape. The first binder has a Young's modulus of at least 600 N/mm2 and no greater than 1600 N/mm2.
