HIGH REFRACTIVE INDEX RESIN FOR OPTICAL MATERIAL, HIGH REFRACTIVE INDEX RESIN COMPOSITION FOR OPTICAL MATERIAL, AND CURED PRODUCT USING THE SAME

Document Type and Number:

Japanese Patent JP2009191159

Kind Code:

A

Abstract:

To provide a high refractive index resin for an optical material and a high refractive index resin composition for an optical material, having a refractive index higher than that of a resin or a composition having PMMA resin or fluorene skeleton, and high transparency, with which a product in any aimed figure can be formed.

The high refractive index resin composition for an optical material contains (A) a resin produced by copolymerization of a monomer expressed by formula (I) and a vinyl monomer copolymerizable with the above monomer, (B) a polymerizable compound having at least one unsaturated bonding group in one molecule, and (C) a photopolymerization initiator or thermal polymerization initiator.
