Title:
FAST-CURING UV-CURABLE COATING LAYER COMPOSITION FOR OPTICAL FIBER
Document Type and Number:
Japanese Patent JP2002060444
Kind Code:
A
Abstract:
To obtain a fast-curing low-viscosity composition for coating an optical waveguide, particularly an optical fiber, and to provide optical fibers coated with the composition.
The coating composition is a radiation-curable composition containing a radiation-curable oligomer, a free radical photoinitiator, and a mixture of reactive diluents including a low-molecular-weight (meth)acrylate having tri-, tetra-, penta- or higher functionality.
