LIQUID CURABLE RESIN COMPOSITION AND CURED MATERIAL THEREOF

摘要

PROBLEM TO BE SOLVED: To obtain a liquid curable resin composition which can be made into a cured material having a surface with reduced frictional force and adhesion and is suitable as a coating material for an optical fiber and a cured material thereof. SOLUTION: This liquid curable resin composition comprises a polymerizable oligomer (A) and a polymerizable monomer (B). The liquid curable resin composition has 0.006μm-2μm arithmetical mean roughness of unevenness on the surface of a cured material and <=5 structures/mm<3> having >=5μm length existing in the cured material.
