  • Method for producing polarizing lens with high refractive index
    Patent number: 9880402
    Abstract: A manufacturing method for a polyurethane based high refractive index polarizing lens comprising polyisocyanate and polythiol, that has no problems such as the generation of bubbles, and has excellent adhesiveness. A manufacturing method for high refractive index polarizing lenses including a process for forming lens layers comprising a polyurethane based polymer formed from polyisocyanate and polythiol on both surfaces of a polarizing film, characterized by using a polarizing film whereof the water content is 4.5 wt % or less as the aforementioned polarizing film.
    Type: Grant
    Filed: May 12, 2004
    Date of Patent: January 30, 2018
    Assignee: Hopnic Laboratory Co., Ltd
