Abstract:
An ink-media set, comprising an ink composition and a recording medium, wherein the ink composition comprises a polymer fine particle containing a dye and an inorganic pigment particle, a water-soluble solvent, and water, and has a surface tension of 20 mN/m to 35 mN/m at 25° C., and the recording medium comprises a support and a coating layer on at least one side of the support, and the amount of pure water transferred to the recording medium is no less than 2 ml/m2 and less than 35 ml/m2 at a contact period of 100 ms and the amount of pure water transferred to the recording medium is no less than 3 ml/m2 and less than 40 ml/m2 at a contact period of 400 ms by measurement of a dynamic scanning absorptometer.
