PHOTOCHROMIC CURABLE COMPOSITION |
摘要 |
<p>A photochromic cured product exhibiting favorable photochromic properties such as a high color density and a large fading rate, and excellent base member properties such as a high hardness, a high heat resistance and a high impact resistance. A curable composition contains a polymerizable monomer which exhibits the L-scale Rockwell hardness of not larger than 40, a bifunctional polymerizable monomer which exhibits the L-scale Rockwell hardness of not smaller than 60, a polyfunctional polymerizable monomer which exhibits the L-scale Rockwell hardness of not smaller than 60, and a photochromic compound.</p> |
