An adhesive composition, a laminated structure, and a method of laminating a structure. The adhesive composition comprises an admixture of unsaturated polymerizable material and a photoreactor, the photoreactor comprising 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-hydroxy-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. The laminated structure includes at least two layers bonded together with the adhesive composition, in which at least one layer is a cellulosic or polyolefin nonwoven web or film. The laminated structure is made by irradiating the adhesive composition to cure the adhesive composition.
