Abstract
A radiation-curable composition having a reduced surface energy and including a reactive dye containing at least one radiation-curable substituent and at least one fluorine-containing substituent. The reactive dye may include any anthraquinone, methine, azo, azine, or xanthene dye adapted to contain at least one radiation-curable substituent and at least one fluorine-containing substituent. The radiation-curable substituent may include (meth)acrylate, styrene, vinyl ether, vinyl ester, N-substituted acrylamide, N-vinyl amide, maleate ester, and fumarate ester.

A radiation-curable composition, comprising a reactive dye comprising at least one radiation-curable substituent and at least one fluorine-containing substituent.
A method for reducing the surface energy of a radiation-curable composition, comprising the step of incorporating a reactive dye comprising at least one radiation-curable substituent and at least one fluorine-containing substituent into a composition comprising one or more of an oligomer, a photoinitiator, a reactive diluent and one or more process additives selected from the group consisting of adhesion promoter, antioxidant, flow control agent, sensitizer, stabilizer, lubricant, and wetting agent.
A method of coating an optical fiber, comprising the steps of:
- heating a preformed glass rod in a draw tower in order to produce a fiber of glass;
- and
- coating the fiber of glass with a radiation-curable composition, comprising a reactive dye comprising at least one radiation-curable substituent and at least one fluorine-containing substituent.
