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 (19)

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:

wherein

R 1 represents a straight chain or branched chain C 2 to C 12 saturated hydrocarbon chain, and

X 1 represents —CH 2 — or —O—; and

wherein

R 2 represents a straight chain or branched chain C 2 to C 12 saturated hydrocarbon chain, and

X 2 represents a hydrogen atom or a straight chain or branched chain C1 to C6 alkyl group, and said ink composition is a water-based pigment ink composition comprising at least a pigment, a second thermoplastic resin, and water.

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 .
