Treatment Liquid for Plastic Film, Primer Liquid for Printing, Ink Composition, and Method for Ink Jet Recording Using Them

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.

AI Technical Summary

Benefits of technology

[0014]The present inventors have now found that plastic recorded matters having significantly improved rubbing resistance, scratch resistance, and waterfastness can be produced by treating the surface of a plastic film on its recording face, that is, by previously coating a specific cyclic ester compound- or specific cyclic amide compound-containing treatment liquid having a specific composition onto the recording face, prior to the deposition, onto the recording face, of a thermoplastic resin-containing water-based ink composition which can be brought to a film upon heating.

Problems solved by technology

Solvent-type inks, however, emit odor of solvents, and, in some cases, harmful components are contained in the solvent volatile component.

Also for UV curable inks, two-component-type curable inks and the like, in some cases, the curable monomer used contains harmful components.

When ink jet recording is carried out using a conventional water-based ink on a non-surface-treated plastic film for ink jet recording, recorded images are unsatisfactory in adhesion, scratch resistance and waterfastness.

This recording method, however, aims to record high-quality and waterfast images on commonly used recording media but does not aim at printing on plastic films.

This publication, however, describes lactams and lactones only as an example of solvents for dissolving a colorant in an ink composition and does not suggest printing of the ink composition onto a recording medium having a recording face formed of a plastic film.

These publications, however, do not suggest advantageous printing of an ink composition onto a recording medium having a recording face formed of a plastic film.
