Abstract:
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.
Abstract:
Provided is a photocurable moisture-proof insulating coating material which places little burden on the environment and has excellent surface curability with low irradiation. In addition, this photocurable moisture-proof insulating coating material is hydrophobic and exhibits high adhesion to a substrate material. Also provided is a novel urethane (meth)acrylate which is used for this moisture-proof insulating coating material. A urethane (meth)acrylate of the present invention is obtained by reacting (a) a polyester polyol that has a structural unit derived from a hydrogenated dimer acid and a structural unit derived from a hydrogenated dimer diol, (b) a polyisocyanate compound and (c) a hydroxyl group-containing (meth)acrylate. A moisture-proof insulating coating material of the present invention contains this urethane (meth)acrylate and a (meth)acryloyl group-containing compound that does not contain a silicon atom.
