12 Claims

1. An adhesive composition comprising: a (meth)acrylate-based resin; and

a polymer having a melting temperature (Tm) of 60° 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 a copolymer of a monofunctional polysiloxane and a monomer,
