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.
