Claim 16:
17. A method of forming a photo-cured layer on a substrate, comprising:
applying a layer of a photocurable composition on the substrate, wherein the photocurable composition comprises a photoinitiator and a polymerizable material, the polymerizable material comprising at least one first polymerizable monomer having a structure of formula (1): (R1)x—Ar—(R2)y (1), with Ar being one or more substituted or unsubstituted aromatic rings; R1 being a structure covalently bonded to Ar including at least one acrylate group; x being 1-4; R2 being —CH═CH2 or —CCH3═CH2 covalently bonded to Ar; y being 1-4, and wherein an amount of the at least one first polymerizable monomer is in a range from 50 wt % to 100 wt % based on the total weight of the polymerizable material;
bringing the photocurable composition into contact with a template or a superstrate;
irradiating the photocurable composition with light to form a photo-cured layer; and
removing the template or the superstrate from the photo-cured layer.
