Abstract
An UV-LED curable clear ink composition for ink jet printing including 44 to 80% by mass of a photo-polymerizable mono-functional monomer, 15 to 50% by mass of a photo-polymerizable poly-functional monomer and 5 to 15% by mass of an acylphosphine photo-polymerization initiator, and having a viscosity at 25° C. of 1 to 50 mPa·s, wherein the photo-polymerizable mono-functional monomer and the photo-polymerizable poly-functional monomer include a photo-polymerizable monomer having at least one of functional groups including an amide group and an amino group, and the photo-polymerizable monomer is contained in an amount of 5 to 20% by mass based on a total amount of photo-polymerizable mono-functional monomer and photo-polymerizable poly-functional monomer.
