Abstract: A resin composition includes at least one (meth)acrylate monomer, a plurality of bifunctional urethane (meth)acrylates, and at least one photoinitiator. The plurality of bifunctional urethane (meth)acrylates includes a first bifunctional urethane (meth)acrylate having a first weight average molecular weight, and a second bifunctional urethane (meth)acrylate having a second weight average molecular weight that is higher than the first weight average molecular weight. A first weight of the first bifunctional urethane (meth)acrylate is greater than or equal to a second weight of the second bifunctional urethane (meth)acrylate with respect to a total weight of the resin composition.
