| titleOfInvention | Non-birefringent optical resin composition and optical element using the same |
| abstract | An optical resin composition having excellent non-birefringence, heat resistance, and transferability to a mold, and an optical element using the composition are provided. The methacrylate or acrylate having an alicyclic hydrocarbon group having 5 to 22 carbon atoms in the ester portion is 5 to 40 parts by weight, the methyl methacrylate is 50 to 80 parts by weight, the N-substituted maleimide is 5 to 40 parts by weight. Parts by weight, 0 to 30 parts by weight of benzyl methacrylate, and 1 to 10 parts by weight of an acrylate or an aromatic vinyl compound having a hydrocarbon group having 1 to 5 carbon atoms in the ester portion, with the total weight being 100 parts by weight A resin obtained by copolymerization at a composition ratio such that the obtained resin has an absolute value of orientation birefringence of less than 1 × 10 −6 , a melt flow rate of 15 g / 10 min or more, and a bending fracture strength of 50 MPa or more. A non-birefringent optical resin composition comprising: and an optical element using the composition. [Selection diagram] None |
