Composition comprising fluorinated, radiation-curable dyes for surface energy control
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.
1. A telecommunication element coated with a radiation-curable composition, comprising a reactive dye comprising at least one radiation-curable substituent and at least one fluorine-containing substituent.
2. The telecommunication element of claim 1 , wherein the telecommunication element is selected from the group consisting of (i) an optical fiber having a core and a cladding surrounding the core, (ii) an optical fiber having a core, a cladding surrounding the core, and one or more polymeric coatings on the cladding, and (iii) an optical fiber ribbon.
3. The telecommunication element of claim 1 , wherein the dye is a derivative of an anthraquinone dye, a methine dye, an azo dye, an azine dye, or a xanthene dye, and the dye comprises at least one radiation-curable substituent and at least one fluorine-containing substituent.
4. The telecommunication element of claim 1 , wherein at least one radiation-curable substituent is selected from the group of substituents consisting of (meth)acrylate, styrene, vinyl ether, vinyl ester, N-substituted acrylamide, N-vinyl amide, maleate ester, and fumarate ester.
5. The telecommunication element of claim 1 , wherein the radiation-curable composition further comprises one or more of a (meth)acrylate urethane oligomer, a photoinitiator, and one or more process additives selected from the group consisting of adhesion promoter, antioxidant, flow control agent, sensitizer, stabilizer, lubricant, and wetting agent.
6. The telecommunication element of claim 1 , wherein the radiation-curable composition comprises from about 0.1 wt % to about 15 wt % of the reactive dye.
