12 Claims

1. An adhesive composition comprising:

a (meth)acrylate-based resin; and

a polymer having a melting temperature (Tm) of 45° C. or higher,

wherein the (meth)acrylate-based resin comprises 50 parts by weight to 70 parts by weight of an alkyl acrylate, 5 parts by weight to 40 parts by weight of an alkyl methacrylate, 0.1 parts by weight to 10 parts by weight of a nitrogen-containing monomer, and 1 part by weight to 30 parts by weight of a hydroxyalkyl acrylate,

wherein the polymer is included in an amount of 1 part by weight to 10 parts by weight, based on 100 parts by weight of the (meth)acrylate-based resin, and

wherein the monomer is represented by Chemical Formula 1:

wherein, in Chemical Formula 1,

X is N or O;

R₁is hydrogen or a methyl group; and

n is an integer of 16 to 20.
