1. An ink jet recording process comprising:
- heating a recording medium of a polyvinyl chloride film 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 40 to 60°
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 2-pyrrolidone, 1,3-dimethyl-imidazolidinone, and N,N′
-dimethylpropylene urea;
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 glycol diethers having a boiling point of 150 to 220°
C., andthe content (W1) of the first solvent in the aqueous ink composition is 4 to 15 mass %;
the content (W2) of the second solvent in the aqueous ink composition is 3 to 8 mass %;
the total content (W1+W2) of the first solvent and the second solvent is 18 mass % or less; and
the content (W3) of the third solvent in the aqueous ink composition is 4 to 20 mass %.

Abstract
Recording onto a non-ink-absorbing recording medium is performed using an aqueous ink composition containing a first solvent composed of at least one selected from 2-pyrrolidone, 1,3-dimethyl-imidazolidinone, and N,N′-dimethylpropylene urea, 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 glycol diethers and heating the non-ink-absorbing recording medium at 40 to 60° C.
