| titleOfInvention | Curable composition and cured product |
| abstract | Provided are a curable composition and a cured product capable of obtaining a cured product having a high Abbe number, excellent transparency and crack resistance, and capable of suppressing a decrease in transparency for a long period of time. It has a solid silica fine particle A having an organic content of 5% by mass or less and a median diameter of 5 to 20 nm, and an alicyclic fused ring, and the glass transition temperature of the homopolymer is 90 to 350 ° C. Meta) acrylate B and epoxy (meth) acrylate C having no aromatic ring and having an ethylenically unsaturated group having an amount of 0.1 to 3.0 mmol / g (provided that the (meth) acrylate B is used. (Excluding), urethane (meth) acrylate D having no aromatic ring (excluding the (meth) acrylate B and the epoxy (meth) acrylate C), an antioxidant, and a polymerization initiator. , Including The antioxidant contains an antioxidant having a phenol moiety and an antioxidant having a sulfide moiety (excluding the antioxidant having the phenol moiety). Of the total of the solid silica fine particles A, the (meth) acrylate B, the epoxy (meth) acrylate C, and the urethane (meth) acrylate D, the solid silica fine particles A account for 3 to 55% by mass. The (meth) acrylate B is 3 to 70% by mass, the epoxy (meth) acrylate C is 10 to 80% by mass, and the urethane (meth) acrylate D is 0 to 60% by mass. The amount of the antioxidant is 0.1 to 10 parts by mass with respect to 100 parts by mass of the solid silica fine particles A, the (meth) acrylate B, the epoxy (meth) acrylate C and the urethane (meth) acrylate D. A curable composition in which the polymerization initiator is 0.1 to 10 parts by mass. |
