Abstract
The present invention relates to a thermal ink-jet printing method including the step of ejecting a water-based ink including pigment-containing polymer particles from a print head by an action of a thermal energy, in which the polymer constituting the polymer particles includes not less than 78% by mass and not more than 88% by mass of a constitutional unit derived from an acrylic acid ester containing a hydrocarbon group having not less than 3 and not more than 8 carbon atoms, and not more than 22% by mass and not less than 12% by mass of a constitutional unit derived from acrylic acid, on the basis of a total mass of whole constitutional units in the polymer constituting the polymer particles; [2] a water dispersion for thermal ink-jet printing used in the above method; [3] a water-based ink for thermal ink-jet printing including the above water dispersion; and [4] a use of the above ink in a thermal ink-jet printing method.
