  • Patent number: 9505235
    Abstract: A recording method includes ejecting an ink on an recording medium, wherein the ink includes a colorant, polymer particles, water, and an aqueous organic solvent, has a static surface tension of equal to or less than 30 mN/m, and has a fluctuation range of a dynamic surface tension from after 1 millisecond to after 1 second of from 0.2 mN/m to 2.0 mN/m when measuring the dynamic surface tension by a maximum bubble pressure method, and wherein the recording medium has a maximum liquid absorption amount of the ink within a contact time of 500 milliseconds measured by a dynamic scanning liquid absorption meter of equal to or greater than 5 ml/m2.
    Type: Grant
