Abstract
An ink jet recording method includes recording with an aqueous ink composition on a non-ink-absorbing or low-ink-absorbing recording medium. The aqueous ink composition contains a water-insoluble colorant, water-insoluble thermoplastic resin particles, a surfactant, a first solvent including at least one selected from 2-pyrrolidone and N,N′-dimethylpropylene urea, a second solvent including 1,2-hexanediol, and a third solvent including at least one selected from glycol diethers having a boiling point of 240° C. or more and 280° C. or less.
Claims6
An ink jet recording method comprising:
- heating a non-ink-absorbing or low-ink-absorbing recording medium to a temperature range of 50° C. or more and 80° C. or less and ejecting ink droplets of an aqueous ink composition on the recording medium with an ink jet recording apparatus;
- and
- heating the recording medium to a temperature range of 60° C. or more and 90° C. or less to dry the aqueous ink composition ejected on the recording medium,
- wherein the aqueous ink composition contains water, at least one water-insoluble colorant, water-insoluble thermoplastic resin particles, a surfactant, a first solvent including at least one selected from 2-pyrrolidone and N,N′-dimethylpropylene urea, a second solvent including 1,2-hexanediol, and a third solvent including at least one selected from glycol diethers having a boiling point of 240° C. or more and 280° C. or less;
- the content (W1) of the first solvent in the aqueous ink composition is 4% to 14% by mass;
- the content (W2) of the second solvent in the aqueous ink composition is 3% to 8% by mass;
- the content (W3) of the third solvent in the aqueous ink composition is 4% to 10% by mass;
- and
- the total (W1+W2+W3) of the contents of the first, second, and third solvents is 22% by mass or less.
