154など。(Prior art) Optical fibers are fragile and easily damaged, and easily break due to the slightest external force, and when mechanical lateral pressure is applied, the light transmitted by microbending weakens. Therefore, to minimize microbending, the glass surface is first coated with a material that has an extremely low modulus of elasticity, and then coated with a material that has a flexible and high modulus of elasticity. Secondary coating has been carried out with materials that have

成物を提供しようとするもである。Although microbending can be suppressed by coating with a locustide material having a low elastic modulus, the hydrogen problem has not been satisfactorily resolved. Even with conventional UV-curable coating materials, large amounts of UV rays are generated when exposed to high temperatures, stored under fluorescent lights for long periods of time, and exposed to high temperatures, causing transmission loss. look. This invention aims to provide a resin composition suitable for a coating material for optical glass fibers, which generates a small amount of hydrogen even when stored under a fluorescent lamp for a long period of time, and has excellent hardness and arsenic properties. .
