The present invention concerns an optical fibre comprising: an optical waveguide comprising a glass core surrounded by a glass cladding; a coating surrounding said optical waveguide comprising a cured polymer material comprising a polyester obtained by polymerization of a monomer selected from an acid, a triglyceride, or a mixture of triglycerides having a C.sub.16-C.sub.24 aliphatic chain comprising at least two conjugated double bonds. The present invention concerns also a method for coating an optical fibre with said polyester coating. The cured polymer material forming the coating can be prepared by curing the polyester of the invention either thermally or by radiation.

A method for manufacturing an optical fiber includes: drawing an optical fiber from an optical fiber preform in a drawing furnace; and cooling the optical fiber in an annealing furnace. When the optical fiber enters the annealing furnace, a temperature difference between a temperature of the optical fiber and a fictive temperature of glass in a core of the optical fiber is 300 C. or less. The optical fiber is cooled for 0.01 seconds or more in the annealing furnace so that the temperature of the optical fiber becomes 1300 C. or more and 1800 C. or less.

The present invention is directed to a glass container having an outer glass surface with an inkjet printed image provided on said surface, characterized in that a CEC with a thickness between 0 to 20 nm is present between the outer glass surface and the inkjet printed image. Such glass container is preferably a one-way beverage bottle. In addition, the present invention is directed to a method of inkjet printing an image on a glass container comprising the steps of: a) manufacturing a glass container having a CEC layer; b) removing at least part of the CEC layer to a level wherein the remaining CEC layer has a thickness of 0 to 20 nm; c) inkjet printing an image on the glass container
