PHOTOCHROMIC CURABLE COMPOSITION |
| 摘要 |
A photochromic curable composition containing, as a radically polymerizable monomer component (A), a (meth)acrylic-amide polymerizable monomer (A1) having 2 to 6 (meth)acryloyloxy groups and 2 to 6 divalent amide groups (—NHCO—), and a non-amide polymerizable monomer (A2) having at least 3 radically polymerizable groups but having no amide bond. From the photochromic composition, there can be obtained a photochromic cured body having excellent photochromic properties such as a high color density, a high fading rate, and excellent mechanical strength. |

1. A photochromic curable composition containing a radically polymerizable monomer component (A) and a photochromic compound (B), wherein said radically polymerizable monomer component (A) contains:
(A1) a (meth)acrylic-amide polymerizable monomer having 2 to 6 (meth)acryloyloxy groups and 2 to 6 divalent amide groups (—NHCO—); and (A2) a non-amide polymerizable monomer having at least 3 radically polymerizable groups but having no amide bond. |
