| titleOfInvention | Synthetic resin lens |
| abstract | PROBLEM TO BE SOLVED: To provide a synthetic resin lens having low specific gravity and good optical and mechanical characteristics. SOLUTION: 50 to 100% by weight of hydroxyl group of component A is reacted with isocyanate group of component B, 10 to 50% by weight of component C, 80 to 20% by weight of component D, and copolymerizable monomer A synthetic resin lens having a specific gravity of less than 1, which is a copolymer obtained by copolymerizing a composition comprising 10 to 50% by weight of a component E as a body. A component The weight ratio of the A1 component and the A2 component is A1: A2 = 90: 10 to 50: A mixture that is 50. Component A1 A diol containing at least one unsaturated group in a structure obtained by reducing a dimer or trimer of a C18 or higher higher unsaturated fatty acid. A2 component An alcohol compound containing a radically polymerizable unsaturated group. Component B A polyisocyanate compound having no cyclopolymerizable unsaturated group and having a cyclocyclic structure. D component Carbonic acid number 12 The above (meth) acrylate. |
