Ink-jet ink and recording method utilizing the same

摘要

An ink-jet ink containing: (i) a colorant; (ii) Solution A containing water, a water miscible organic solvent and an amphiphilic polymer, wherein Solution A satisfies all of the following requirements: Scheme (1) A1>A2; Scheme (2) B1>B2 Scheme (3) A1/B1>1 provided that A1 is a Stokes diameter of the amphiphilic polymer in Solution A; B1 is an optical scattering diameter of the amphiphilic polymer in Solution A; A2 is a Stokes diameter of the amphiphilic polymer in Solution A after a content of water in Solution A is evaporated by an amount of 10 to 30 wt % from an initial Solution A; and B2 is an optical scattering diameter of the amphiphilic polymer in Solution A after a content of water in Solution A is evaporated by an amount of 10 to 30 wt % from an initial Solution A.
