Pressure-sensitive adhesive composition

A pressure-sensitive adhesive composition comprising:

• (A) a block copolymer comprising a first block having a glass transition temperature of 50° C. or higher and a second block having a glass transition temperature of −10° C. or less, wherein a hydroxyl group is present in the first or second block;
• (B) a multifunctional isocyanate compound;
• (C) a multifunctional epoxy compound or a multifunctional aziridine compound;
• and
• (D) at least one compound selected from the group consisting of an imidazole compound, a phosphine compound, an amine compound, and a phenolic compound, wherein the amine compound is a compound represented by the following Formula 3:
• wherein L1 and L2 are each independently an alkylene group,
• wherein the (B) multifunctional isocyanate compound is included at a content of 0.1 to 10 parts by weight, based on 100 parts by weight of the (A) block copolymer,
• wherein the (C) multifunctional epoxy compound or multifunctional aziridine compound is included at a content of 0.01 to 10 parts by weight, based on 100 parts by weight of the (A) block copolymer, and
• wherein the (D) compound is included at a content of 0.001 to 0.1 parts by weight, based on 100 parts by weight of the (A) block copolymer.
