Abstract
A composition having at least about 10 percent perfluoroalkylsulfonamideoethyl acrylate; at least about 5 percent aliphatic urethane acrylate oligomer; at least about 1 percent acrylate monomer; and less than about 84 percent other reactive and non-reactive components. The composition, with the addiction of a light absorbing pigment, is particularly useful as a light absorbing adhesive in an optical element such as a rear projection screen that incorporates totally internally reflecting structures to disperse the light passing through the screen.
