| 摘要 |
The present invention provides an active energy ray-curable composition for an optical material, which is excellent in terms of low viscosity, storage stability, low foaming properties, low-temperature curing, less warpage, depth curability, heat-resistant and light-resistant transparency, rubber properties, crack resistance, resistance to moisture penetration, and designability; a cured product thereof; and a method for producing the same. The present invention relates to an active energy ray-curable composition for an optical material, including: (A) a vinyl polymer that has per molecule at least one (meth) acryloyl group represented by formula (1), is produced by living radical polymerization, and has a color difference ”E* of 10 or less; (B) a photo-radical polymerization initiator; and (C) at least one antioxidant selected from the group consisting of hindered phenol antioxidants, hindered amine antioxidants, and phosphorus antioxidants, the formula (1) being
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ-OC(O)C(R a )=CH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein R a represents a hydrogen atom or a C1-20 organic group. |
