A polymerizable composition for an optical material and a method for producing the same, a method for producing a transparent resin, and a method for producing a lens base material. |
| abstract |
PROBLEM TO BE SOLVED: To provide a polymerizable composition for an optical material and a method for producing the same, which can stably prepare a thiourethane-based optical material in which coloring is suppressed while using a polyene compound and an aromatic polyisocyanate with good reproducibility. Etc. are provided. A method for producing a polymerizable composition for an optical material, which comprises an aromatic polyisocyanate, a polyene compound having two or more ethylenically unsaturated double bonds and a halogen concentration of 1 ppm or more and less than 150 ppm, and polythiol. [Selection diagram] None |
