Provided are a photocurable composition a cured product of which does not cause yellowing when photocured and has good mechanical properties and such a cured product of the photocurable composition. A photocurable composition according to the present invention comprising
(A) a terminal-modified (hydrogenated) polybutadiene represented by formula [I]:
(wherein R 1 represents a hydrogen atom or a methyl group, R 2 and R 3 each independently represent a C1-C10 linear or branched alkylene group, a C3-C8 cycloalkylene group optionally substituted by a C1-C6 alkyl group, or a combination of the groups thereof, A represents a polymer chain obtained by polymerizing butadiene, or a polymer chain obtained by hydrogenating the former polymer chain thereof, and m represents 1 or 2)
(B) a (meth)acrylic acid ester monomer, and
(C) a photo-radical polymerization initiator. And a cured product of the photocurable composition can be obtained by photocuring the photocurable composition. |
