Title:
ACTINIC RAY-CURABLE INKJET INK COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/276290
Kind Code:
A1
Abstract:
There have been inkjet ink compositions for reducing migration. In addition to such a feature, the present invention addresses the problem of obtaining a sufficient ability to adhere to a resin film and excellent LED curability, and performing printing on a film that is for food packaging requiring stricter properties. As a solution to the problem, provided is an actinic ray-curable inkjet ink composition that satisfies all of requirements (A) to (F). (A) Containing 20.0-60.0 mass% of a hydroxy group-containing monofunctional (meth)acrylate with respect to the total amount of all polymerizable components. (B) Containing a polyfunctional monomer having an ether bond. (C) Containing 10.0-50.0 mass% of an amine-modified oligomer with respect to the total amount of all polymerizable components. (D) Containing, as a polymerization initiator, ethyl phenyl(2,4,6-trimethylbenzoyl)phosphinate. (E) Containing a polymer sensitizer.
