To provide a photopolymerizable coating agent or the like which is a novel photopolymerizable composition having excellent heat resistance or the like, can easily and rigidly be adhered irrespective of kinds of a variety of optical films by using a photopolymerizable adhesive or the like using the photopolymerizable composition when laminating a variety of the optical films, is excellent in hardenability by photopolymerization at a low-exposure light quantity, substantially does not include an organic solvent, and is low in viscosity.
A photopolymerizable composition has an oxirane compound (A) as a main component, contains, with respect to 100 pts.wt. of the oxirane compound (A), 0.5 to 10 pts.wt. of a photopolymerization initiator (B), and furthermore, contains a cyclic compound (C). The photopolymerizable composition is characterized in that the composition contains 0.05 to 3 pts.wt. of a water component (F) in 100 pts.wt. of the photopolymerizable composition, and substantially does not contain an organic solvent.
