A cured matter obtained by polymerizing and curing a polymerizable composition comprising a compound having at least one episulfide in a molecule is reduced in an odor by adding a perfume to the polymerizable composition comprising the compound having at least one episulfide in a molecule.
A cloudiness of the lens is removed by raising a purity of sulfur to 98 % or more.
A reduction in a chlorine content of the sulfur compound described above to 0.1 % by weight or less elevates an oxidation resistance and a light fastness of the high refractive index optical material and improves a color tone thereof.
An optical product having a high refractive index and a high-degree transparency is provided by subjecting the composition in advance to deaerating treatment at 0 to 100°C for one minute to 24 hours under a reduced pressure of 0.001 to 50 torr.
通过聚合和固化包含分子中至少含有一种表硫化物的化合物的可聚合组合物而获得的固化物,可通过向包含分子中至少含有一种表硫化物的化合物的可聚合组合物中添加香料来减少气味。
将硫的纯度提高到 98% 或更高,可消除镜片的浑浊度。
将上述硫化合物的氯含量降低到 0.1%(重量百分比)或更低,可提高高折射率光学材料的抗氧化性和耐光性,并改善其色调。
在 0.001 至 50 托的减压条件下,将组合物预先在 0 至 100°C 的温度下进行 1 分钟至 24 小时的脱气处理,可获得具有高折射率和高透明度的光学产品。
