Patent ID: 11549031

Abstract:
Embodiments provide a coating material including (A) 100 parts by mass of an active-energy-ray-curable resin, (B) 5 to 200 parts by mass of aluminum oxide particles having an average particle diameter of 1 to 100 μm, (C) 0.1 to 20 parts by mass of aluminum oxide microparticles having an average particle diameter of 1 to 100 nm, and (D) 0.1 to 40 parts by mass of a compound having at least two isocyanate groups per molecule, where the active-energy-ray-curable resin (A) includes (a1) 70 to 99% by mass of a polyfunctional (meth)acrylate and (a2) 30 to 1% by mass of an acrylamide compound having at least one hydroxyl group per molecule, and the sum total of the amount of the polyfunctional (meth)acrylate (a1) and the amount of the acrylamide compound (a2) having at least one hydroxyl group per molecule is 100% by mass.
