Abstract:
1. A solvent-free photocurable resin composition consisting of: a hexafunctional urethane(meth)acrylate oligomer in an amount of from 10 to 45 wt% of the total resin composition, a trifunctional (meth)acrylic acid ester monomer selected from the group consisting of glycerol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol penta(meth)acrylate, and dipentaerythritol hexa(meth)acrylate in an amount of from 5 to 40 wt% of the total resin composition, a photopolymerization initiator, and a dilution monomer, wherein the dilution monomer consists of a fluorine-based (meth)acrylic acid ester monomer having three or more and less than seventeen fluorine atoms in its molecule and a monofunctional or difunctional (meth)acrylic acid ester monomer in amounts of from 10 to 40 wt% and from 10 to 30 wt% of the total resin composition, respectively, and wherein the photocurable resin composition, when photocured, forms a scratch-resistant film.
