    • A pressure-sensitive adhesive composition curable with actinic energy rays which comprises a copolymer comprising 0.1 to 30 wt.%, preferably 0.1 to 3 wt.%, structural units derived from an imide (meth)acrylate represented by general formula (1) and 70 to 99.9 wt.%, preferably 97 to 99.9 wt.%, structural units derived from an ethylenic monomer such as an alkyl (meth)acrylate having a C4-12 alkyl group. In formula (1), R and R each independently is hydrogen or C1-4 alkyl, one of R and R is hydrogen and the other is C1-4 alkyl, or R and R are bonded to each other to form a carbon ring; R is C1-6 alkylene; R is hydrogen or methyl; and n is an integer of 1 to 6. The pressure-sensitive adhesive composition is usable as one-pack type, has excellent storage stability, and does not necessitate any step such as heating or aging when used. The cured article obtained therefrom is excellent in bonding strength and holding power, is substantially odorless, and is extremely suitable for use in pressure-sensitive adhesive sheets, etc.
    • 一种可用光化能射线固化的压敏粘合剂组合物,该组合物含有一种共聚物,该共聚物含有0.1至30重量%,优选0.1至3重量%由通式(1)表示的酰亚胺(甲基)丙烯酸酯衍生的结构单元和70 至99.9重量%,优选97至99.9重量%的衍生自具有C4-12烷基的(甲基)丙烯酸烷基酯的烯属单体的结构单元。 在式(1)中,R 1和R 2各自独立地为氢或C 1-4烷基,R 1和R 2中的一个为氢且另一个为C 1-4烷基, R 1和R 2彼此结合形成碳环; R 3是C 1-6亚烷基; R 4是氢或甲基; 并且n是1至6的整数。压敏粘合剂组合物可用作单组分型(one-pack type),具有优异的储存稳定性,并且在使用时不需要任何步骤如加热或老化。 由此获得的固化物品的粘合强度和保持力优异,基本上无臭,并且非常适合用于压敏粘合片等。
