ABSTRACT:
An optical material formed of a copolymer is disclosed. The copolymer is obtained by polymerizing a monomer composition composed of a particular N-substituted trifunctional monomer having a triazine ring structure and a monomer copolymerizable with the isocyanurate. Where the copolymerizable monomer is a specific aliphatic bifunctional monomer, the monomer composition additionally contains a further monomer which is copolymerizable with the aforementioned components and contains at least one ethylenically-unsaturated group.
