<p>A composition (86) 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 (86), with the addition of a light absorbing pigment, is particularly useful as a light absorbing adhesive (86) in an optical element such as a rear projection screen (88, 90) that incorporates totally internally reflecting structures (24) to disperse the light passing through the screen (88, 90).</p> |
