| titleOfInvention |
Polythiourethane polymerization compositions having high impact resistance and preparation method of optical resin using them |
| abstract |
The present invention relates to a resin composition for a urethane-based optical lens and an optical lens cured by using the resin composition for a urethane-based optical lens, which overcomes the problem of the impact resistance, which is a disadvantage of the conventional plastic optical lens. The resin composition of the present invention is constituted as a polythiol compound and a polyisocyanate compound, and the urethane-based optical lens obtained by reacting therewith has a low specific gravity and is excellent in heat resistance, workability such as moldability and dyeability, ultraviolet barrier property, It has excellent optical properties. Especially, it solves the problem of low impact resistance after hard-multi coating. |
