Active energy ray curable composition, active energy ray curable printing ink using the same, and printed matter

摘要

An active energy ray-curable printing ink that exhibits high curability when used in a printing ink and has excellent offset printability, an active energy ray-curable printing ink that combines excellent curability and offset printability, and Provide the printed matter. The aromatic polyisocyanate (a), the hydroxyl group-containing mono (meth) acrylate (b), and the polyol (c) are essential reaction raw materials, and the number of moles of isocyanate groups contained in the aromatic polyisocyanate (a) (a ′ ) The ratio [(b ′) / (a ′)] of the number of moles of hydroxyl group (b ′) contained in the hydroxyl group-containing mono (meth) acrylate (b) to 0.99 to 0.40, Active energy ray curing comprising a urethane (meth) acrylate resin (A) having a (meth) acryloyl group concentration of 1.5 to 4.0 mmol / g and a polymerization initiator (B). Sex composition.
