Claim Text:
1. A method for ink jet recording, comprising: depositing a treatment liquid onto a recording medium having a recording face formed of a plastic film, said treatment liquid comprising at least a main solvent, a cyclic ester compound selected from the group consisting of γ-butyrolactone and ε-caprolactone, a surfactant, and an organic solvent having low surface tension; evaporating water from the deposited treatment liquid to evaporate a part of the cyclic ester compound; and ejecting and depositing droplets of an ink composition onto the recording face while the deposited treatment liquid is not in a fully dried state and a surface of the plastic film is in a dissolved state, wherein the organic solvent having low surface tension is diethylene glycol monobutyl ether or triethylene glycol monobutyl ether, the content of the cyclic ester compound is 0.1 to 50.0% by weight of the treatment liquid, and the content of the surfactant is 0.01 to 5.0% by weight of the treatment liquid, and when the treatment liquid is deposited on the plastic film, the surface of the plastic film is dissolved by the cyclic ester compound, and then the plastic film and the treatment liquid are mixed.
