The present invention relates to a radiation-curable solvent-free coating composition for optical fiber having a radiation-curable urethane (meth)acrylate oligomer comprising an alkyd backbone,a reactive diluent, and a photoinitiator, and optionally an additive.

Radiation-curable coating composition

The present invention relates to a radiation-curable solvent-free coating composition for optical fiber having a radiation-curable urethane (meth)acrylate oligomer comprising an alkyd backbone, a reactive diluent, a photoinitiator and, optionally, an additive.

Radiation-curable compositions comprising oligomers having an alkyd backbone

A radiation-curable fiber optic coating composition for an inner primary coating includes a coloring agent, preferably a dye or a dye precursor, compatible with the fiber of the fiber optic and capable of imparting a pre-selected color to the inner primary coating, or another coating. The coloring agent can be a reactive dye. Any of the dyes preferably is stabilized by a stabiliser in the colored coating layer, or, preferably, in a more exterior layer.

Radiation-curable composition with simultaneous color formation during cure

A radiation-curable coating composition for an optical fiber comprising a reactive functionality-terminated urethane oligomer, wherein said oligomer comprises the reaction product of (i) a semi-crystalline polyol, and (ii) a non-crystalline polyol in the mole ratio of semi-crystalline polyol to non-crystalline polyol of at least about 1:1, (iii) at least one isocyanate, and (iv) an endcapping compound capable of supplying the functionality terminus.

Non-crystal-forming oligomers for use in radiation-curable fiber optice coatings

Radiation-curable oligomers radiation-curable compositions, coated optical glass fibers, and ribbon assemblies

Provided is a ribbon assembly having the functional capability of providing mid-span access without the use of additives, monomers or oligomers containing fluorine or silicone. The ribbon assembly is formulated from an oligomer which reduces the surface energy of the ink coating and/or the matrix material.
