In relation to a polymerizable composition for forming a transparent optical resin layer to be interposed between an image display section of an image display device and a light-transmissive protective section thereof, the present invention provides a polymerizable composition that does not give rise to display defects caused by the deformation of the image display section, enables high-luminance, high-contrast image displaying, has excellent heat resistance, and also has a low dielectric constant. This polymerizable composition comprises: (1) a urethane (meth)acrylate obtained by reacting a hydrogenated polyolefin polyol and a compound having an isocyanato group and a (meth)acryloyl group; (2) a (meth)acryloyl-group-containing compound having a hydrocarbon group with a carbon number of 6 or greater; and (3) a photopolymerization initiator.
Provided are a polymerizable compound, a photocurable composition, and a photocurable moisture-proof insulating coating material for mounting circuit boards, which reduce environmental impact, excel in surface curability at low irradiation dose, and have high adhesion to substrate materials. The compound according to the present invention has a structural unit derived from a dimerdiol and has, as an end group, a group represented by formula (1):
wherein R
1
represents H or CH
3
and R
2
represents a hydrocarbon group having 2 to 12 carbon atoms, at an end thereof. Preferably, the compound has, as end groups, the group represented by formula (1) and a group represented by formula (2):
wherein R
