An ink-jet printing method for printing images or characters on a recording medium using a water-based ink for ink-jet printing, in which the water-based ink comprises pigment-containing water-insoluble polymer particles A, water-insoluble polymer particles B, an organic solvent C and water; the water-insoluble polymer particles A comprises a water-insoluble polymer (a) containing a constitutional unit derived from an ionic monomer (a-1), a constitutional unit derived from an aromatic ring-containing hydrophobic monomer (a-2) and a constitutional unit derived from a hydrophilic monomer (a-3) represented by the formula: wherein R 1 is a hydrogen atom or a methyl group; R 2 is a hydrogen atom, an alkyl group having not less than 1 and not more than 20 carbon atoms or a phenyl group whose hydrogen atom may be substituted with an alkyl group having not less than 1 and not more than 9 carbon atoms; and m represents an average molar number of addition of ethyleneoxy groups and is a number of not less than 7 and not more than 100, the constitutional unit derived from the hydrophilic monomer (a-3) being present in an amount of not less than 13% by mass and not more than 45% by mass on the basis of whole constitutional units in the water-insoluble polymer (a); the organic solvent C comprises one or more organic solvents having a boiling point of 90°C or higher, and has an average boiling point of 250°C or lower as a weighted mean value of boiling points that are weighted by a content (% by mass) of respective organic solvents in the organic solvent C; and the recording medium has a water absorption of not less than 0 g/m 2 and not more than 10 g/m 2 as measured in a pure water contact time of 100 ms. the water-based ink comprises pigment-containing water-insoluble polymer particles A, water-insoluble polymer particles B, an organic solvent C and water; the water-insoluble polymer particles A comprises a water-insoluble polymer (a) containing a constitutional unit derived from an ionic monomer (a-1), a constitutional unit derived from an aromatic ring-containing hydrophobic monomer (a-2) and a constitutional unit derived from a hydrophilic monomer (a-3) represented by the formula: wherein R 1 is a hydrogen atom or a methyl group; R 2 is a hydrogen atom, an alkyl group having not less than 1 and not more than 20 carbon atoms or a phenyl group whose hydrogen atom may be substituted with an alkyl group having not less than 1 and not more than 9 carbon atoms; and m represents an average molar number of addition of ethyleneoxy groups and is a number of not less than 7 and not more than 100, the constitutional unit derived from the hydrophilic monomer (a-3) being present in an amount of not less than 13% by mass and not more than 45% by mass on the basis of whole constitutional units in the water-insoluble polymer (a); the organic solvent C comprises one or more organic solvents having a boiling point of 90°C or higher, and has an average boiling point of 250°C or lower as a weighted mean value of boiling points that are weighted by a content (% by mass) of respective organic solvents in the organic solvent C; and the recording medium has a water absorption of not less than 0 g/m 2 and not more than 10 g/m 2 as measured in a pure water contact time of 100 ms. wherein R 1 is a hydrogen atom or a methyl group; R 2 is a hydrogen atom, an alkyl group having not less than 1 and not more than 20 carbon atoms or a phenyl group whose hydrogen atom may be substituted with an alkyl group having not less than 1 and not more than 9 carbon atoms; and m represents an average molar number of addition of ethyleneoxy groups and is a number of not less than 7 and not more than 100, the constitutional unit derived from the hydrophilic monomer (a-3) being present in an amount of not less than 13% by mass and not more than 45% by mass on the basis of whole constitutional units in the water-insoluble polymer (a); the organic solvent C comprises one or more organic solvents having a boiling point of 90°C or higher, and has an average boiling point of 250°C or lower as a weighted mean value of boiling points that are weighted by a content (% by mass) of respective organic solvents in the organic solvent C; and the recording medium has a water absorption of not less than 0 g/m 2 and not more than 10 g/m 2 as measured in a pure water contact time of 100 ms.
