| titleOfInvention | Optical element having high refractive index, optical lens and resin composition |
| abstract | PROBLEM TO BE SOLVED: To provide a high refractive index of nd1.55 or more, low residual birefringence, and excellent optical basic characteristics of high light transmittance, and Provided is an optical element having high thermal stability, low water absorption, and excellent moldability. SOLUTION: An optical element, an optical lens and a resin composition comprising a silicon-based resin represented by the following average composition formula [I]. Average composition formula [I] (R 1 ) a (R 2 ) b SiO (4-ab) / 2 [wherein R 1 may be the same or different, and each represents a hydrogen atom, a hydroxyl group, an amino group, or a substituent. Or a group selected from an unsubstituted aliphatic group, an alicyclic group, an aryl group, a heterocyclic group, or a group in which these groups are bonded to a silicon atom via oxygen. R 2 represents a biaryl group having a bond axis capable of imparting internal rotational isomerism or an organic group substituted by the biaryl group. However, 0 ≦ a <1.5, 0.3 <b < 1.8, 0.8 <a + b <1.8. ] |
