METHOD FOR PRODUCING OPTICAL MATERIAL |
摘要 |
The present invention provides a method for producing an optical material comprising a predetermined (a) compound (b) compound (c) compound (d) compound and (e) compound wherein the compounding method minimizes the occurrence of a defect where peeling traces on a lens linger. Going through a first step to fifth step minimizes the defect where peeling traces linger. First step: a step for dissolving the (b) compound into the (a) compound to obtain a first solution. Second step: a step for adding the (e) compound to the first solution obtained in the first step and then mixing to obtain a second solution not comprising the (d) compound. Third step: a step for adding the (c) compound to the second solution obtained in the second step to obtain a reaction mixture. Fourth step: a step for adding the (d) compound to the reaction mixture obtained in the third step and then mixing to obtain a resin composition for an optical material. Fifth step: a step for cast molding the resin composition for an optical material obtained in the fourth step and then polymerizing to obtain the optical material. |
