| titleOfInvention | Radiation curable resin composition and optical member |
| abstract | A radiation curable resin composition having an appropriate viscosity before curing and having a high refractive index and a high Abbe number after curing is provided. The composition of the present invention is obtained by reacting (A) (a) polythiol with (b) a compound having an alicyclic structure and two or more (meth) acryloyl groups. A compound having the above (meth) acryloyl group, (B) a compound other than the component (A) having an alicyclic structure and an ethylenically unsaturated group, and (D) a photopolymerization initiator. In the composition of the present invention, (C) the Abbe number of the cured product obtained by polymerizing alone is 40 or more and having an ethylenically unsaturated group, other than (A) component and (B) component And / or (E) a compound having a brominated aryl group and a (meth) acryloyl group. The cured product of the composition of the present invention has a refractive index (n D 25 ) of 1.555 or more and an Abbe number of 48 or more. [Selection figure] None |
