An adhesive composition includes an acryl copolymer having a hydroxyl group and a weight average molecular weight of 800,000 to 1,500,000 g/mol; an isocyanate-based cross-linking agent, an aliphatic hydrocarbon solvent having 6 to 10 carbon atoms, and an acid additive having a molecular weight of 40 to 100 g/mol, thus low viscosity characteristics may be maintained for a long period of time, and thereby stirring and coating may be easily performed while it does not require an excess of diluted solvent. |
