Abstract:
1. An active-energy-ray-curable resin composition comprising: a urethane (meth)acrylate (A) prepared through a reaction in which a polyalkylene glycol (C) having a weight-average molecular weight (Mw) in a range of 5,000 to 30,000, a polyisocyanate (D), and a (meth)acrylate (E) intramolecularly including a hydroxyl group serve as essential raw-material components; and a polyfunctional (meth) acrylate (B), with a mass ratio [(A)/(B)] of (A) to (B) being in a range of 0.1/99.9 to 15/85, wherein the polyfunctional (meth)acrylate (B) includes both a monomeric (meth) acrylate (b1) having a functionality of 4 or more and an oligomeric polyfunctional (meth) acrylate (b2) that has a molecular weight in a range of 600 to 3,000.
