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;
