Abstract
The present application relates to an adhesive composition and an adhesive film, wherein the adhesive composition includes a prepolymer and a third (meth)acrylate monomer, and the prepolymer is produced by polymerization of a mixture including a photopolymerizable functional group-containing first (meth)acrylate monomer and a second (meth)acrylate monomer.
Claims14
An adhesive composition comprising:
- a prepolymer and a third (meth)acrylate monomer,
- wherein the prepolymer is produced by polymerization of a monomer mixture including a first (meth)acrylate monomer containing a photopolymerizable functional group;
- and a second (meth)acrylate monomer, wherein the second (meth)acrylate monomer comprises an aliphatic functional group-containing (meth)acrylate monomer, an alicyclic functional group-containing (meth)acrylate monomer, and a polar functional group-containing (meth)acrylate monomer,
- wherein a weight average molecular weight of the prepolymer is 5,000 g/mol to 100,000 g/mol,
- wherein a content of the prepolymer is not less than a content of the third (meth)acrylate monomer, and
- wherein a content of the third (meth)acrylate monomer is 40 parts by weight to 50 parts by weight with respect to 100 parts by weight of the adhesive composition.
