| 摘要 |
The invention provides a composition containing (A) one or more (meth)acrylate compounds selected from among a (meth)acryl-modified silicone fluid, a long-chain alkyl (meth)acrylate, and a polyalkylene glycol (meth)acrylate having a number average molecular weight of 400 or more; (B) a (meth)acrylate compound having an alicyclic hydrocarbon group which has six or more carbon atoms and which is bonded to the compound via an ester bond; (C) (meth)acrylic acid or a (meth)acrylate compound having a polar group; and (D) a radical polymerization initiator. The composition is suitably employed as a raw material for, for example, an encapsulating material or a lens, exhibits transparency and heat resistance comparable to conventional levels, and provides a cured product exhibiting excellent adhesion to a base member surrounding the cured product. |
