    • PURPOSE: An adhesive composition for optical film is provided to remarkably improve production efficiency and productivity of an optical film because effective coating process is possible in state of a large amount of solid phase, and to accurately and uniformly control physical properties such as a thickness of an adhesive layer. CONSTITUTION: An adhesive composition for optical film comprises: 100.0 parts by weight of an acrylic polymer comprising a radically polymerizable group and a thermosetting function group, and has a weight average molecular weight is 1,000,000; and 0.01-1.0 parts by weight of a crosslinking agent capable of reacting with the thermosetting functional group. A coating solid content of the adhesive composition is 20 weight% or more. The absolute value of different between a peel strength after 4 days since attached to a glass substrate with an adhesive form and a peel strength after 15 days sine attached.
    • 目的:提供用于光学膜的粘合剂组合物,以显着提高光学膜的生产效率和生产率,因为在大量固相的状态下可以进行有效的涂布工艺,并且精确地和均匀地控制物理性能如 粘合剂层。 构成:用于光学膜的粘合剂组合物包括:100.0重量份包含自由基聚合性基团和热固性官能团的丙烯酸类聚合物,其重均分子量为1,000,000; 和0.01-1.0重量份能够与热固性官能团反应的交联剂。 粘合剂组合物的涂布固体成分为20重量%以上。 附着于粘合剂玻璃基板4天后的剥离强度与15天正电极附着后的剥离强度的绝对值不同。
