Document Type and Number:
WIPO Patent Application WO/2013/161642
Kind Code:
A1
Abstract:
A photochromic curable composition of the present invention is characterized by containing, as (A) radically polymerizable monomer components, (A1) a (meth)acryl amide polymerizable monomer which has 2-6 (meth)acryloyloxy groups and 2-6 divalent amide groups (-NHCO-) and (A2) a non-amide polymerizable monomer which has at least three radically polymerizable groups and no amide bond. This photochromic curable composition is capable of providing a photochromic cured body that has excellent photochromic characteristics such as high developed color density and high fading speed, while exhibiting excellent mechanical strength.
