Adhesive composition, adhesive film comprising same, back plate film comprising adhesive film and plastic organic light-emitting display comprising adhesive film

An adhesive composition comprising:

• a (meth)acrylate-based resin;
• and
• a polymer having a melting temperature (Tm) of 35° C. to 50° C.,
• wherein the (meth)acrylate-based resin comprising 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 includes a copolymer of a monofunctional polysiloxane and two monomers,
• wherein the monofunctional polysiloxane is included in an amount of greater than or equal to 10 parts by weight and less than or equal to 40 parts by weight, and the two monomers are included in a total amount of greater than or equal to 60 parts by weight and less than or equal to 90 parts by weight, based on 100 parts by weight of the polymer,
• 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 two monomers are each independently represented by Chemical Formula 1:
• wherein in Chemical Formula 1,
• X is N or O;
• R1 is hydrogen or a methyl group;
• and
• n is an integer of 10 to 30.
