Title:
RESIN COMPOSITION FOR OPTICAL MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/077219
Kind Code:
A1
Abstract:
Provided is a resin composition for an optical material. The resin composition has a low viscosity even if formulated having high quantities of zirconium oxide particles and an organic silicon compound, is capable of inhibiting yellowing, and forms a resin having a high refractive index and exhibiting excellent transparency and heat resistance. The resin composition for an optical material is characterized by including zirconium oxide particles having an average particle size in the range of 1-30nm, a dispersant comprising a compound represented by formula (1), an organic silicon compound, and a compound having polymerizable unsaturated groups. In formula (1), R is a branched-chain C3-24 alkyl and/or alkenyl group, AO is a C1-4 oxyalkylene group, n is a value in the range of 3-30 expressing the average number of moles of alkylene oxide added, and X is a linking group comprising carbon, hydrogen, and/or oxygen.
