COATING COMPOSITIONS

摘要

Photocurable coating compositions useful for coating optical glass fibres comprising: (a) a polyethylenically unsaturated polyurethane derived from a polyol having pendent fluoroalkyl groups; (b) an ethylenically unsaturated monomer which is a liquid solvent for the polyethylenically unsaturated polyurethane and is copolymerisable therewith, and (c) a photo-initiator composition. s
