Document Type and Number:
Japanese Patent JP6863800
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a cycloolefin-based resin composition that realizes an optical component having transparency and a high refractive index.SOLUTION: The cycloolefin-based resin composition includes (A) a polar group-containing cycloolefin-based copolymer and (B) inorganic fine particles finely dispersed in a matrix of the polar group-containing cycloolefin-based copolymer (A). The polar group includes at least one kind selected from a carboxyl group, a hydroxyl group, a sulfonic acid group, an acid anhydride group and an amino group and a constitutional unit derived from a monomer having the polar group is positioned inside the main chain or in the side chain of a polymer chain of the polar group-containing cycloolefin-based copolymer (A).SELECTED DRAWING: None
