Title:
CURABLE LIQUID RESIN COMPOSITION
Document Type and Number:
Japanese Patent JP2007119705
Kind Code:
A
Abstract:
To provide a curable liquid resin composition having quick curability and good storage stability and giving an optical fiber element having high immersion resistance in hot water.
The curable liquid resin composition contains (A) 35-85 mass% urethane (meth)acrylate having a structure derived from a polyether polyol, (B) 1-60 mass% compound containing ethylenic unsaturated group other than the compound A, (C) 0.01-1 mass% amine-based photosensitizer and (D) 0.01-10 mass% photopolymerization initiator (based on 100 mass% of the total composition), and the sum of zinc and cobalt elements in the composition is 0.5-10 ppm determined by inductively coupled plasma mass spectrometry (ICP-MS).
