Abstract:
1. An ink jet recording process comprising: heating a non-ink-absorbing or low-ink-absorbing recording medium to a temperature range of 40 to 60° C. and discharging droplets of an aqueous ink composition with an ink jet recording apparatus; and heating the recording medium to a temperature range of 50 to 90° C. to dry the aqueous ink composition discharged on the recording medium, wherein the aqueous ink composition contains: water; at least one kind of water-insoluble coloring agent; water-insoluble thermoplastic resin particles; a surfactant; a first solvent composed of at least one selected from glycol diethers having a boiling point of 150 to 220° C.; a second solvent composed of at least one selected from 1,2-hexanediol and 1,2-pentanediol; and a third solvent composed of at least one selected from glycols having a boiling point of 170 to 220° C., and the content (W1) of the first solvent in the aqueous ink composition is 5 to 20 mass %; the content (W2) of the second solvent in the aqueous ink composition is 3 to 10 mass %; the content (W3) of the third solvent in the aqueous ink composition is 5 to 15 mass %; and the total content (W2+W3) of the second solvent and the third solvent is 22 mass % or less.
