A polymer coated fiber, a polymer-coated web, and a method of coating a fiber or a web. The fiber or web is coated with a composition comprising an admixture of unsaturated polymerizable material and a photoreactor, and the composition on the fiber or web is irradiated with an amount of radiation sufficient to cure the composition and form a coating on the fiber or web. The photoreactor comprises a wavelength-specific sensitizer covalently bonded to a reactive species-generating photoinitiator. Suitable wavelength-specific sensitizers have a molar extinction coefficient greater than about 5000 liters per mole per cm at an absorption maximum and resulting photoreactors have a quantum yield of greater than about 0.5 at an absorption maximum. Suitable photoreactors include 2-p-(2-methyllactoyl)phenoxy!ethyl-1,3-dioxo-2-isoindolineacetate, 2-hydr oxy-2-methyl-4'-2-p-(3-oxobutyl)phenoxy!ethoxy!propiophenone, 4-p-(4-benzoylcyclohexyl)oxy!phenyl!-2-butanone, and 1,3-dioxo-2-isoindolineacetic acid diester with 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylpropiophenone.
