CURABLE LIQUID COMPOSITION, CURED LAYERAND COATED OPTICAL FIBER

摘要

A curable liquid resin optical fiber coating composition comprising 0.1 to 10 wt%, relative to the total weight of the composition, of an alkoxysilane compound (A) which does not contain a radically polymerizable functional group, and 0.01 to 1 wt%, relative to the total weight of the composition, of a hindered amine compound. (B). This curable liquid resin composition produces a cured product that ensures a high n- value of the coated optical fiber and an excellent fiber strength after coating removal.
