Title:
RESIN COMPOSITION, SECONDARY COATING MATERIAL FOR OPTICAL FIBER, AND OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2019/194198
Kind Code:
A1
Abstract:
This resin composition includes: a base resin, which contains a urethane (meth)acrylate oligomer, a monomer having a phenoxy group, and a photopolymerization initiator; and hydrophobic inorganic oxide particles. The viscosity at 45°C is 300-4200 mPa∙s. The contained amount of the monomer having a phenoxy group is 1-30% by mass in terms of the total amount of base resin.
