A photopolymerizable composition comprising:
(I) a photopolymerizable oligomer of formula (1), or of formula (2),
wherein R1 is a hydrogen atom or a methyl group,
R2 and R3 are organic groups, X is oxygen or sulfur, n is a number not smaller than 1, and m is a number not smaller than 2,
or a combination of the above photopolymerizable oligomer and other ethylenically unsaturated monomer which is copolymerizable therewith; and
(II) a catalytic amount of a photo-initiator, may be cured to produce a transparent cured product by irradiation. The product obtained exhibits excellent properties and, particularly, excellent surface precision.
