Treatment liquid for plastic film, primer liquid for printing, ink composition, and method for ink jet recording using them

摘要

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.

主权项

1. An ink-jet ink composition for forming an image on a recording face formed of a plastic film by dissolving a surface of the plastic film, said ink composition comprising:
a cyclic ester compound selected from the group consisting of γ-butyrolactone, ε-caprolactone, δ-hexandolactone, propylene carbonate, ethylene carbonated, and 1,3-dioxin-2-one, a thermoplastic resin; a cyclic ether compound selected from the group consisting of oxirane, oxacyclobutane (oxetane), tetrahydrofuran (oxolane), 3-methyl-oxolane, oxane, 1,3-dioxolane, 1,3-dioxane, 1,4-dioxane, 2-methyltetrahydrofuran, and 1,3,5-trioxane, a colorant; and a main solvent, wherein the plastic film is selected from polyvinyl chloride, polyethylene terephthalate, polycarbonate, polystyrene and polyurethane, where when the ink-jet ink composition is deposited onto the plastic film, the ink-jet ink composition dissolves the plastic film, wherein the content of the cyclic ester compound is 0.1% to 10.0% by weight based on the total amount of the ink-jet composition, and wherein the content of the cycler ether compound is 0.1% to 10.0% by weight based on the total amount of the ink-jet ink composition.
