Abstract
Disclosed herein is a coating composition comprising a silsesquioxane component having one or more reactive functional groups that render it curable using ultraviolet radiation; where the one or more reactive functional groups are selected from the group consisting of an acrylate, a vinyl ether, or an epoxy; and optionally, a co-reactive non-silsesquioxane monomer and/or an oligomer having one or more reactive functional groups that are curable using ultraviolet radiation and are selected from the group consisting of free radically curable acrylates, cationically curable epoxies, and cationically curable vinyl ethers; where the coating composition is disposed and cured on an optical article; where the optical article is at least one of an optical fiber or an optical planar waveguide; and where the average functionality of the composition is greater than one.
