ACTIVE ENERGY RAY-CURABLE INK COMPOSITION FOR INKJET RECORDING AND PRINTED ARTICLE

摘要

Disclosed is an active energy ray-curable ink composition for inkjet recording, which contains 30-80% by mass of a monofunctional acrylate having a monocyclic alicyclic structure, 1-10% by mass of a urethane acrylate oligomer, 5-30% by mass of N-vinylcaprolactam, a polymerization initiator and a coloring agent. The active energy ray-curable ink composition for inkjet recording has a viscosity at 40°C of 5-20 mPa·s and a surface tension of 20-50 mN/m. The active energy ray-curable ink composition for inkjet recording has good ejectability, good curability, low odor and high safety, while exhibiting good adhesion to a wide range of bases.
