Optical resin composition comprising a thiourethane prepolymer and use thereof |
摘要 |
Disclosed are: (1) an optical resin composition comprising Component A: a thiourethane prepolymer compound prepared by reacting a polythiol compound having at least 3 functional groups and an intramolecular sulfide bond, with a polyisocyanate compound in a molar ratio of -SH to -NCO ranging from 3.0 to 7.0 Component B: at least one (meth)acrylate compound having at least 2 functional groups; and Component C: a compound radically polymerizable with Components A and B, in 10 to 50% by weight, 35 to 70% by weight, and 5 to 30% by weight, respectively; (2) a preparation process for an optical resin by photopolymerization; (3) an optical resin; and (4) a prepolymer suitable for Component A. The composition is a novel, rapidly polymerizable composition for an optical resin. Furthermore, a resin prepared by curing the composition not only has a high refractive index and a high Abbe number, but also is excellent in transparency and optical homogeneity.
