Abstract
A resin composition includes a first (meth)acrylate monomer a second (meth)acrylate monomer containing an oxy group or a divalent alkyl group, a urethane (meth)acrylate oligomer, and at least one photoinitiator. A content of the first (meth)acrylate monomer is about 1.6 to about 4.7 times greater than a content of the urethane (meth)acrylate oligomer.
Claims20
A resin composition comprising:
- a first (meth)acrylate monomer represented by Formula 1;
- a second (meth)acrylate monomer containing a substituted or unsubstituted oxy group or a substituted or unsubstituted divalent alkyl group having 4 to 18 carbon atoms;
- a urethane (meth)acrylate oligomer;
- and
- at least one photoinitiator,
- wherein a content of the first (meth)acrylate monomer is about 1.6 to about 4.7 times greater than a content of the urethane (meth)acrylate oligomer,
- wherein, in Formula 1,
- R1 is a hydrogen atom, or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms,
- R2 is a substituted or unsubstituted divalent alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted divalent alkenyl group having 2 to 10 carbon atoms, a divalent alkenyl group including an ether bond and having 2 to 10 carbon atoms, or a substituted or unsubstituted divalent alkynyl group having 2 to 10 carbon atoms, and
- R3 and R4 are each independently a substituted or unsubstituted alkyl group having 1 to 10 carbon atoms, a substituted or unsubstituted alkenyl group having 2 to 10 carbon atoms, a substituted or unsubstituted alkynyl group having 2 to 10 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 20 ring-forming carbon atoms.
