Coating material for optical glass fiber

Abstract

Abstract PURPOSE:To prevent the thermal decomposition or stripping of a primary coating material for an underlayer by blending a prescribed percentage of an acrylic oligomer or monomer with a prescribed percentage of a prescribed compound having a fluoroalkyl group. CONSTITUTION:The titled material which is cured under radiation and used to form a secondary coating consists of 1-30wt% compound such as fluoroalkyl (meth)acrylate and 70-99wt% acrylic oligomer or monomer. The compound has a fluoroalkyl group contg. at least one hydrogen atom and a (meth)acrylic group in one molecule. When the secondary coating material is used, the thermal decomposition or stripping of a primary coating material is prevented.
