| titleOfInvention | Composition for plastic lens |
| abstract | (57) [Summary] [Structure] Component (A) represented by formula (I), component (B) which is a urethane poly (meth) acrylate compound having two or more (meth) acrylate groups in one molecule. And the component (C) represented by the general formula (II) has a molar ratio of an isopropenylphenyl group of (A): a (meth) acrylate group of (B): a (meth) acrylate group of (C). Is 1.0: 0.1-0.8: 1.0-2.0, and (A) has an isopropenylphenyl group: (B) And a composition for a plastic lens containing (C) in a total molar ratio of (meth) acrylate groups of 1.0: 1.2 to 2.5. [Effect] It is possible to obtain a lens that can be polymerized in a short time, has a small optical distortion, a low specific gravity, and is excellent in transparency, impact resistance, and dyeability. |
