Method for producing resin for optical material having excellent color tone and transparency |
| abstract |
(57) [Problem] To prevent coloring and fogging of a resin for an optical material obtained by curing and polymerizing an epithio compound blended with an ultraviolet absorber. When curing and polymerizing an epithio compound using a catalyst, the amount of the ultraviolet absorber and the catalyst satisfying the following relational expressions at the same time with respect to 100 parts by weight of the total of the epithio compound, the ultraviolet absorber and the catalyst. Added. 0.001 part by weight ≤ ultraviolet absorber ≤ 1.000 parts by weight 0.001 part by weight ≤ catalyst ≤ 1.000 parts by weight |
