Abstract

This invention provides a treatment liquid for an ink jet recording medium having a recording face of a plastic film, wherein the treatment liquid including at least a specific cyclic ester compound or a specific cyclic amide compound, a primer liquid for printing, and an ink composition. According to the present invention, a plastic recorded matter possessing excellent adhesion and waterfastness can be formed on a recording medium having a recording face of a plastic film.

Claims

1. A method for ink jet recording, comprising coating a primer liquid onto a recording face of a recording medium having the recording face of a plastic film to form a primer film and then ejecting and depositing droplets of an ink composition onto the primer film to perform printing, wherein

said primer liquid comprises at least

a heterocyclic ketone compound selected from the group consisting of cyclic ester compounds of formula (1), cyclic amide compound of formula (2), and a combination thereof,

a first thermoplastic resin, and

a main solvent,

said first thermoplastic resin being dispersed in said primer liquid:

2. The method according to claim 1, wherein the first thermoplastic resin forms a resin film by drying of the primer liquid.

3. The method according to claim 1, which further comprises before the deposition of the ink composition a drying step of evaporating the a main solvent in the primer liquid.

4. The method according to claim 2, wherein the mixed layer of the heterocyclic ketone compound with the plastic film dissolved by the heterocyclic ketone compound adheres to the resin film.

5. The method according to claim 2, which further comprises a heating step of heating the ink composition deposited onto the recording face to form a resin film.

6. The method according to claim 1, wherein the first thermoplastic resin has a composition identical to the second thermoplastic resin.

7. The method according to claim 1, wherein the plastic film is polyvinyl chloride film.

8. A recorded matter printed by a method according to claim 1.
