SUPER-HIGH REFRACTIVE INDEX OPTICAL RESIN COMPOSITION HAVING HIGH HEAT DEFLECTION TEMPERATURE AND EXCELLENT THERMAL STABILITY, OPTICAL LENS USING SAME AND METHOD FOR MANUFACTURING THE OPTICAL LENS |
摘要 |
<p>The present invention relates to a urethane-based optical resin composition having a high heat deflection temperature and a method for manufacturing an optical lens using the composition. A monomer composition for a plastic optical lens according to the present invention is lightweight and has excellent plasticity, dyeability, transparency, shock resistance, etc., and especially has a high initial heat deflection temperature, thereby reducing central deformation of the lens and cracking of the multi-film of the lens due to heat. Further, the monomer composition has excellent thermal stability to reduce discoloration of the lens due to heat.</p> |
