Inkjet recording method

摘要

The inkjet recording method includes ejecting an inkjet ink toward a recording medium to form an ink image on the recording medium. The inkjet ink includes a pigment, water, a surfactant, and a compound having a formula (1) CH3OCH2CH2CON(CH3)2, and optionally includes a compound having a formula (2) CH3CH2CH2CH2OCH2CH2CON(CH3)2. The inkjet recording method satisfies a relation, 16≦γ cos θ≦26, wherein γ represents the surface tension of the inkjet ink in units of mN/m, and θ represents the angle of contact of the inkjet ink with the recording medium in units of degree measured 0.1 seconds after dropping an droplet of the inkjet ink with a volume of 2.5 μl on the recording medium.
