    • Disclosed is an adhesive composition for optical use and, more particularly, an adhesive composition which includes; 30 to 80 wt. % of a mono-functional urethane acrylate oligomer having a weight average molecular weight of 10,000 and 35,000, 10 to 60 wt. % of an acrylate monomer; and 0.1 to 10 wt. % of a free radical photo-initiator, so as to retain physical properties of the adhesive composition such as coating property and adhesiveness and, in addition, reduce incurring of setting shrinkage during photo-polymerization, thereby exhibiting a uniform thickness and excellent surface appearance, durability such as heat resistance and moist heat resistance, and storage elasticity. Moreover, the inventive composition does not contain an alternative solvent, thus enabling manufacturing of a thick film type adhesive film.
    • 公开了一种用于光学用途的粘合剂组合物,更具体地,涉及一种粘合剂组合物,其包括: 30〜80重量% %的重均分子量为10,000和35,000的单官能聚氨酯丙烯酸酯低聚物,10至60重量% %的丙烯酸酯单体; 和0.1〜10wt。 %的自由基光引发剂,以保持粘合剂组合物的物理性能如涂布性能和粘合性,并且另外减少光聚合期间凝固收缩的发生,从而表现出均匀的厚度和优异的表面外观, 耐久性如耐热性和耐湿热性以及储存弹性。 此外,本发明的组合物不含有替代溶剂,因此能够制造厚膜型粘合剂膜。
