本発明は樹脂組成物で被覆した光伝送用ガラスフ−ｆイ
バに係り、特に生産性を向上するのに好適な披涜光伝送
用ガラスファイバに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glass fiber for optical transmission coated with a resin composition, and more particularly to a glass fiber for optical transmission that is suitable for improving productivity.
一般に光、ファイバの材質としては主として石英ガラス

する方法が提案されている。Generally, quartz glass is mainly used as the material for optical fibers. However, even if there are minute defects on this glass surface, 14! The mechanical strength is significantly reduced, making it impractical. Therefore, a method has been proposed in which a liquid rubber or resin composition is applied to the surface of a glass fiber and baked using an electric furnace or the like.
しかしながら、このような方法では硬化速度が遅いため

ァイ・く表面に被覆する前に硬化する可能性があり、長
尺の光ファイバの連続被覆が困難になる。However, such a method has a slow curing speed and requires large equipment to increase productivity. In addition, in order to increase the curing speed, there is a method of using a highly reactive composition, but in this case, it hardens as soon as it comes into contact with the optical fiber that has residual heat from drawing, so it does not affect the surface of the optical fiber. It may harden before coating, making continuous coating of long optical fibers difficult.
本発明は斯かる状況に鑑み、製造面における生産性の高
い被覆光ファイバを提供することを目的とする。In view of this situation, the present invention aims to provide a coated optical fiber with high productivity in terms of manufacturing.

成のものとした点にある。A feature of the present invention is that the surface of a glass fiber for optical transmission is coated with a photocurable composition mainly composed of polysiloxane containing at least one carbon-carbon double bond in the molecule,
This photocurable composition has a structure that is cured by ultraviolet irradiation.

In general, addition-polymerized liquid silicone rubber such as RT/Licone rubber and LPS (Licone product) are usually composed of two components, one of which is carbon-carbon. It is borinorokidunes with carbon double bonds. However, it is not necessarily limited to this. In addition,
These components may be used alone or in combination of two or more. Further, it may be diluted with a plasticizer, a reactive diluent, an organic solvent, or the like.

This may be done in two steps, but it may also be done by semi-curing the surface to the extent that it will not stick even if it is soaked with solid matter, and then completely curing it with a culm.

か、押出被覆も可能であり、製造方法に多様性がある。As described above, according to an embodiment of the present invention, a glass fiber for optical transmission is coated with a photocurable composition mainly composed of polysiloxane having a carbon-carbon-1-Jj bond, and is cured by ultraviolet irradiation. This structure increases production speed, has a long pot life, and
Good flexibility and good adhesion can be obtained. It should be noted that in addition to being able to be coated by coating in the same manner as conventional liquid liquor, extrusion coating is also possible, and there is a wide variety of manufacturing methods.
