Document Type and Number:
WIPO Patent Application WO/2018/135421
Kind Code:
A1
Abstract:
Provided is a contact lens monomer composition useful for manufacturing a contact lens having excellent surface hydrophilicity, oxygen permeability, mechanical strength, and wear comfort. Furthermore provided are a contact lens polymer obtained from the composition, and a contact lens. The composition contains specific amounts of: (A) a methacrylate monomer having a phosphorylcholine group; (B) one or more types of hydroxyl-group-containing monomers selected from the group consisting of hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, hydroxybutyl (meth)acrylate, hydroxyethyl acrylamide, ethylene glycol monovinyl ether, and diethylene glycol monovinyl ether; (C) an itaconic acid diester monomer containing a siloxanyl group; (D) a siloxanyl-group-containing (meth)acrylate; and (E) a crosslinking agent.
