Abstract
The invention relates to an optical glass fibre 1 having a synthetic resin coating which consists of at least two layers 2 and 3 in which the first layer 2 is formed from an elastomer forming material which can be cured by exposure to actinic radiation, and in which the optical glass fibre exhibits a great tensile strength, a small risk of static fatigue fracture and a low ageing rate, owing to the fact that the synthetic resin composition comprises between 0.1 and 5% by weight of one or more phosphorus compounds of the following structural formula: ##STR1## wherein n has a value of 1 or 2 and wherein R represents an organic group, preferably an organic group which co-reacts during curing of the elastomer forming material and is built into the polymeric network thus formed.
