| titleOfInvention | Synthetic resin lens |
| abstract | PROBLEM TO BE SOLVED: To provide a synthetic resin lens made of a specific copolymer, which has a low specific gravity, a high refractive index, excellent dyeability and transparency. SOLUTION: The reaction product obtained by reacting the following A component, B component, and C component is a copolymer of D component, E component and F component, and has a refractive index of 1.58 or more and a specific gravity of 1 or more. .2 Less than synthetic resin lenses. Component A: Bisphenol A adduct of ethylene oxide or propylene oxide or a mixture thereof (the number of repeating units of the adduct: 1 to 1) 6). Component B: a compound having an unsaturated group capable of undergoing radical polymerization with a hydroxyl group. Component C: an aromatic isocyanate having two or more isocyanate groups in one molecule. D component; A A reaction product obtained by reacting component, component B, and component C. E component: aromatic vinyl compound copolymerizable with D component. F Component: an aliphatic polythiol having two or more mercapto groups in one molecule copolymerizable with the D component and the E component. |
