Abstract: Provided is a biocompatible material capable of forming a gel having excellent retention and scratch resistance. The biocompatible material according to the embodiment of the present invention includes an alginate having a weight-average molecular weight of 1 million or more, an aluminum compound, a carboxyvinyl polymer, and an oil-based base material. However, the biocompatible material is substantially free of water.

Abstract: Provided are the following compound represented by General Formula (A) or (B), a curable resin composition including the compound, a cured product thereof, an optical member, and a lens:




A ring Ar1 and a ring Ar2 represent an aromatic ring represented by a specific formula or a fused ring thereof, R1 and R2 represent a specific substituent, and v and w are a specific integer. R3 and R4 represent a hydrogen atom or a monovalent substituent, L1 and L2 represent an alkylene group having 1 to 6 carbon atoms, and Spa to Spd represent a single bond or a divalent linking group. Pol1 and Pol2 represent a hydrogen atom or a polymerizable group, in which at least one of Pol1 or Pol2 is a polymerizable group. Further, in the formulae, a structure represented by (R1)v—Ar1/cyclopentadiene skeleton/Ar2—(R2)w is not line-symmetrical.
