<p>Provided is a radiation-curable pressure-sensitive adhesive composition for optical members. When being cured (crosslinked), the radiation-curable pressure-sensitive adhesive composition can attain sufficient progression of crosslinking reaction, without suffering from the inhibition of reaction caused by excessive scavenging of free radicals. When used in bonding adherends, the radiation-curable pressure-sensitive adhesive composition exhibits excellent durability and light leak resistance even under high-temperature conditions or high-temperature and -humidity conditions, and further is inhibited from photoaging and thus prevents the occurrence of faults associated therewith. A radiation-curable pressure-sensitive adhesive composition for optical members, which comprises (A) a specific (meth)acrylic copolymer, (B) a radiation-curable acrylic compound having two (meth)acryloyl groups in the molecule, (C) a radiation-curable acrylic compound having 3 to 10 (meth)acryloyl groups in the molecule, (D) a hydrogen-abstraction type photopolymerization initiator, (E) an isocyanate-type crosslinking agent having two or more isocyanate groups in the molecule, and (F) a specific light stabilizer in specific amounts respectively.</p> |
