AI Technical Summary

Benefits of technology

The solution significantly enhances the adhesion and durability of printed matter on plastic films, preventing separation from external forces and water ingress, while ensuring safety and stability of the printing process.

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.
