Ultraviolet-curable Resin Composition, Cured Product, and Optical Member

摘要

The present invention relates to an optical member fabricated by laminating together at least two substrates by means of a cured product layer of an ultraviolet-curable resin composition containing (A) a (meth)acrylic polymer having a weight average molecule weight of 1,500 to 30,000, (B) a (meth)acrylate compound having a (meth)acrylic equivalent of 200 g/eq. or more and having at least two (meth)acryloyl groups, and (C) a photopolymerization initiator, and an ultraviolet-curable resin composition for laminating together at least two substrates, and is useful as an optical transparent adhesive exhibiting high curability, allowing for lesser shrinkage during curing, and being excellent in the transparency of the cured product as well as in the adhesiveness to a substrate and the flexibility.
