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. |
