POLYESTER RESIN, OPTICAL LENS, AND OPTICAL LENS SYSTEM |
| 摘要 |
The polyester resin according to the present invention is a polyester resin mainly including a diol structural unit and a dicarboxylic acid structural unit, wherein 10 to 84 mol % of the diol structural unit is a structural unit derived from ethylene glycol, 16 to 90 mol % of the diol structural unit is a structural unit derived from neopentyl glycol represented by a particular formula (i), and 50 to 100 mol % of the dicarboxylic acid structural unit is a structural unit derived from a naphthalenedicarboxylic acid. Further, the optical lens according to the present invention is obtained by molding the polyester resin. Furthermore, the optical lens system according to the present invention includes the optical lens and an additional optical lens. |
