Inkjet recording method and inkjet recording device

摘要

An inkjet recording method including applying stimuli to inkjet recording ink to make the ink jet onto recording medium, wherein the recording medium includes support, and surface layer provided on at least one surface of the support, where transfer amount of pure water with contact time of 100 ms determined by measuring the surface of the recording medium to which the surface layer is provided by dynamic scanning absorptometer is 1 to 10 mL/m2, the recording medium is surface-treated through corona discharge or plasma treatment, the ink contains water-dispersible colorant, organic solvent, surfactant, and water, the organic solvent contains at least one polyhydric alcohol having equilibrium moisture content of 30% by mass or greater at 23° C. and 80% RH, and dynamic surface tension of the ink, as measured by maximum bubble pressure method with surface lifetime of 15 ms, is 35 mN/m or lower at 25° C.

1. An inkjet recording method, comprising:
applying stimuli to an inkjet recording ink to make the inkjet recording ink jet onto a recording medium to thereby form an image, wherein the recording medium contains a support, and a surface layer provided on at least one surface of the support, where a transfer amount of pure water with contact time of 100 ms determined by measuring the surface of the recording medium to which the surface layer is provided by means of a dynamic scanning absorptometer is 1 mL/m2 to 10 mL/m2, wherein the recording medium is surface treated through a corona discharge treatment, or a plasma treatment, wherein the inkjet recording ink contains a water-dispersible colorant, an organic solvent, a surfactant, and water, wherein the organic solvent contains at least one polyhydric alcohol, which has an equilibrium moisture content of 30% by mass or greater at temperature of 23° C. and relative humidity of 80%, and wherein a dynamic surface tension of the inkjet recording ink, as measured by a maximum bubble pressure method with surface lifetime of 15 ms, is 35 mN/m or lower at 25° C.
