Production method and resin composition of thiourethane-based optical material resin using general-purpose polyisocyanate compound, and produced optical material |
| abstract |
A method for producing a high-quality thiourethane-based optical material using a general-purpose polyisocyanate compound, a resin composition therefor, and a produced optical material. In order to solve the whitening caused by the elution of the adhesive from the adhesive tape during lens casting, the reaction rate is increased by adjusting the polythiol compound obtained in the production process to pH 3.1-7. A thiourethane-based optical material with no whitening on the edge of the lens and no uneven polymerization. [Selection figure] None |
