Abstract
A resin composition comprises a urethane (meth)acrylate oligomer. The resin composition has a storage modulus of about 2×103 Pa to about 2×104 Pa when irradiated with 200 mJ/cm2 of an ultraviolet light.
Claims11
An adhesive member comprising:
- a polymer, the polymer being derived from a resin composition containing a urethane (meth)acrylate oligomer, wherein
- the resin composition, before curing, has a viscosity of about 20 mPa·s or less at about 30° C. to about 50° C., wherein
- the resin composition of the adhesive member has a storage modulus of about 2×103 Pa to about 2×104 Pa at 25° C. and 1 Hz when irradiated with about 200 mJ/cm2 of ultraviolet light,
- the resin composition of the adhesive member has a storage modulus of about 1×104 Pa to about 1×105 Pa at 25° C. and 1 Hz when irradiated with about 4000 mJ/cm2 of ultraviolet light, and
- the adhesive member has a peel strength of about 1 kg/25 mm or greater when the resin composition is cured, and
- wherein the resin composition includes no organic solvent.
