ADHESIVE COMPOSITIONS AND OPTICAL FILMS USING THE SAME

摘要

PURPOSE: An adhesive composition is provided to ensure excellent storage stability and adhesion while not degrading the transparency of an optical film without additional processes and facilities. CONSTITUTION: An adhesive composition comprises a compound having an azetidinium functional group, polyvinylalcohol-based resin and basic compound. The change of viscosity and pH for 7 days is less than 5%. A method for preparing the adhesive composition comprises a step for injecting a compound having an azetidinium functional group, polyvinyl alcohol-based resin and basic compound, and stirring the materials at 60-90°C for 3-24 hours.
