PROCESS FOR MAKING AN OPTICAL FIBRE WITH A SYNTHETIC COATING

摘要

Method of manufacturing an optical fibre having a synthetic resin coating and optical fibre having a synthetic resin coating manufactured according to the method. The invention provides a method of rapidly coating an optical fibre with two layers of a synthetic resin, the first layer being formed from a reactive molten synthetic resin material. This molten synthetic resin material is solidified by cooling after which the second layer, which can be any customary curable synthetic resin composition, is applied. Next, both layers are cured together, for example, by exposure to UV-light. The reactive molten synthetic resin material comprises at least two acrylate ester groups per molecule.
