Title:
RESIN COMPOSITION, SECONDARY COATING MATERIAL FOR OPTICAL FIBER, OPTICAL FIBER, AND METHOD FOR MANUFACTURING OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2022/130855
Kind Code:
A1
Abstract:
The resin composition includes a base resin containing a photopolymerizable compound and a photopolymerization initiator and surface-modified silica particles. The surface-modified silica particles have a T unit in which three oxygen atoms are bonded to a silicon atom as a structural unit of silicone, and the proportion of T1 units included in the T unit is 29 mol% or less.
