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. An ink-jet ink composition for formulation of an image having a recording face formed of a plastic film, wherein said ink composition comprising at least

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

thermoplastic resin,

colorant, and

main solvent,

said thermoplastic resin being dispersed in said ink composition:

2. The ink-jet ink composition according to claim 1, wherein in formula (1), R¹ represents a straight chain or branched chain C2 to C5 saturated hydrocarbon group.

3. The ink jet ink composition according to claim 1, wherein said cyclic ester compound is selected from the group consisting of γ

-butyrolactone, ε

-caprolactone, propylene carbonate, and ethylene carbonate.

4. The ink-jet ink composition according to claim 1, wherein, in formula (2), R² represents a straight chain or branched chain C2 to C5 saturated hydrocarbon group and X² represents a hydrogen atom or a methyl group.

5. The ink-jet ink composition according to claim 1, wherein the cyclic amide compound is selected from the group consisting of 2-pyrrolidone, N-methyl-2-pyrrolidone, and ε

-caprolactoam.

6. The ink-jet ink composition according to claim 1, which further comprises a surfactant and wherein said surfactant is an acetylene glycol surfactant.

7. The ink-jet ink composition according to claim 1, which further comprises an organic solvent having low surface tension, and wherein said organic solvent having low surface tension is diethylene glycol monobutyl ether or triethylene glycol monobutyl ether.

8. A method for formulation of an image by ink jet recording, characterized by comprising ejecting and depositing droplets of an ink composition onto a recording medium having a recording face of a plastic film to perform printing, wherein said ink-jet ink composition is an ink composition according to claim 1.

9. The method according claim 8, which further comprises a heating step of heating the ink composition deposited onto the recording face to form a resin film.

10. The method according to claim 8, wherein the recording face is polyvinyl chloride film.

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