Photocurable resin composition, method of fabricating optical film using the same, and optical film including the same

摘要

A photocurable resin composition includes an ester (meth)acrylate, an antistatic agent, a silicone additive, an initiator, and at least one UV-curable unsaturated compound. The at least one UV-curable unsaturated compound may include a monofunctional or multifunctional UV-curable monomer, and a (meth)acrylate containing about 10 mol % or more of an ethylene oxide group.

1. A photocurable resin composition for an optical film, comprising:
(a) a UV-curable unsaturated compound including a (meth)acrylate containing about 10 mol % to about 50 mol % of an ethylene oxide group; (b) a monofunctional or multifunctional monomer and a phosphagen acrylate; (c) an ester (meth)acrylate; (d) an antistatic agent; (e) a silicone additive; and (f) an initiator, wherein: the monofunctional or multifunctional monomer includes one or more of phenoxybenzyl (meth)acrylate, bisphenol F (meth)acrylate, novolac epoxy (meth)acrylate, phenyl phenoxyethyl (meth)acrylate, bisphenol A epoxy (meth)acrylate, ethoxylated thiodiphenyl di(meth)acrylate, fluorene (meth)acrylate or phenylthioethyl (meth)acrylate, the phosphagen acrylate is represented by Formula 2: where R is represented by Formula 3: where R1 represents hydrogen, a C1 to C10 linear or branched alkyl group, or a C6 to C30 aryl, aryl alkyl, or alkyl aryl group, and n represents an integer from 1 to 5, and (a) and (b) combined include:
about 30 to about 45 wt % of the (meth)acrylate containing the ethylene oxide group,about 30 to about 60 wt % of the monofunctional or multifunctional monomer, andabout 10 to about 25 wt % of the phosphagen acrylate.
