1. A resin composition comprising:
a (meth)acrylate (A) comprising a hydroxy group and having a molecular weight of about 500 or less;
a polymer (B) comprising polyisoprene or polybutadiene as a main skeleton, having at least one radical reactive group in one molecule, and having a molecular weight in a range of about 2,000 to about 35,000;
a monofunctional (meth)acrylate (C) different from the (meth)acrylate (A); and
a urethane (meth)acrylate oligomer (D) having a molecular weight of about 6,000 or greater, wherein
the resin composition has a glass transition temperature in a range of about −50° C. to about 0° ° C. after the resin composition is cured,
the resin composition has a viscosity in a range of about 5 mPa·s to about 50 mPa·s at a temperature in a range of about 30° C. to about 50° C., and
with respect to a total amount of the resin composition, the resin composition comprises:
the (meth)acrylate (A) in an amount in a range of about 5 wt % to about 30 wt %;
the polymer (B) in an amount in a range of about 0.1 wt % to about 5 wt %;
the monofunctional (meth)acrylate (C) in an amount in a range of about 50 wt % to about 88 wt %; and
the urethane (meth)acrylate oligomer (D) in an amount in a range of about 1 wt % to about 15 wt %.
