| titleOfInvention | Casting polymerization manufacturing method for plastic lens |
| abstract | (57) [Abstract] [Purpose] An object of the present invention is to discover and develop a resin having not only a high refractive index but also good processability for cast polymerization, and to provide a novel lens with high productivity by the resin. And [Constitution] The following formula (I) [Chemical formula 1] (In the above formula, X represents hydrogen, chlorine, bromine, a methyl group, or an ethyl group, Z represents hydrogen, or a methyl group, and a and b Satisfying the relations of 2 ≦ b ≦ 4, 1 ≦ a ≦ 4, and a + b ≦ 6), and at least one monomer compound selected from the benzene ring-containing polyisocyanates represented by the following formula (II): [Chemical 2] (In the above formula, R 1 represents a phenol group, a hydroxyl group, or an amino group) is mixed with at least one monomer compound selected from allyl group-containing compounds, and then cast polymerization is performed. A method of manufacturing a plastic lens, comprising: [Effect] Good transparency and hardness, high refractive index, In addition, a lens having excellent processability, impact resistance, solvent resistance, etc. can be obtained. |
