Patent ID: 8754167

Claim:
An active energy ray-curing composition comprising: an active energy ray-curing prepolymer (A) obtained by a reaction of an acrylic-based prepolymer having a hydroxyl group and an acrylic monomer (a4) having an isocyanate group and a (meth)acryloyl group; an active energy ray-curing compound (B) having a benzotriazole group and a (meth)acryloyl group; another active energy ray-curing compound (C) having a (meth)acryloyl group and being different from the (A) component and the (B) component; and inorganic oxide particles (D), the acrylic-based prepolymer having the hydroxyl group being a copolymer including as monomer units: an acrylic monomer (a1) having a piperidinyl group and a (meth)acryloyl group; an acrylic monomer (a2) having a hydroxyl group and a (meth)acryloyl group; and another monomer (a3).
