    Abstract: Aqueous coating compositions include dispersed polyurethane-vinyl polymer hybrid particles obtained by free-radical polymerization of at least one vinyl monomer in the presence of a polyurethane. The polyurethane and the vinyl polymer in the hybrid particles are present in a weight ratio of polyurethane to vinyl polymer ranging from 1:1 to 20:1, and the polyurethane is the reaction product of at least the following components: (a) from 5 to 40 wt. % of at least one organic difunctional isocyanate, (b) from 0.5 to 4 wt. % of an isocyanate-reactive compound containing ionic or potentially ionic water-dispersing groups having a molecular weight of from 100 to 500 g/mol, (c) from 40 to 80 wt. % of at least one diol having a molecular weight from 500 to 5000, (d) from 0 to 10 wt. % of at least one active-hydrogen chain extending compound with a functionality of at least 2 other than water, (e) from 0 to 10 wt. % of at least one diol having a molecular weight below 500 g/mol. The isocyanate and hydroxy groups on the components used are present in a respective mole ratio (NCO to OH) in the range of from 0.8:1 to 5:1.

    Abstract: Radiation curable compositions for coating optical fibers are disclosed herein. In an embodiment, a radiation curable composition includes a reactive oligomer component, wherein a portion of the polymerizable groups of the reactive oligomer component include methacrylate groups; a reactive diluent monomer component, wherein a portion of the polymerizable groups of the reactive diluent monomer component include acrylate groups, acrylamide groups, or N-vinyl amide groups, or combinations thereof; a photoinitiator component, and an optional additive component. Also described are methods of coating the radiation curable compositions elsewhere described, and the fiber optic coatings and cables resulting therefrom.
