どが用いられているが、光フアイバとの密着性に
劣り、吸湿した場合光フアイバの強度を劣化させ
る欠点がある。 Optical glass fibers (hereinafter referred to as optical fibers) used for optical transmission are fragile, easily damaged, and have poor flexibility. Destroy. Therefore, conventionally, optical fibers have been coated with a resin on their surfaces immediately after being spun from a glass base material. Such resin coating materials include:
Epoxy resins, urethane resins, silicone resins, and the like are used, but they have the drawback of poor adhesion to optical fibers and deterioration of the strength of optical fibers when they absorb moisture.
この発明は上記の問題点を解決するためになさ

のである。 This invention was made to solve the above problems, and is based on the following general formula: (R 1 is an alkylene group, R 2 is an alkyl group) It is characterized by containing as a main component an unsaturated polyester using a diol having a siloxane bond in the molecule as part or all of the glycol component. This invention relates to coating materials for optical fibers.

のとなる。 The coating material of the present invention can be easily cured by applying light or heating after being applied to the surface of an optical fiber, and as a result, it adheres well to the surface of the optical fiber and also Even when exposed to the atmosphere, the above adhesion is not significantly impaired. Therefore, the coated optical fiber exhibits great strength not only under normal conditions but also under high humidity conditions, and has greatly improved optical transmission characteristics compared to those using conventional coating materials.
