Abstract: Processing tapes have special properties to permit them to be used to prepare laminate articles, such as security articles. The processing tapes include a backing, a pressure sensitive adhesive layer and a release surface covering the pressure sensitive adhesive layer. The backing is a dimensionally stable transparent polymeric film, and the surface on which the pressure sensitive is coated may be a treated surface. The pressure sensitive adhesive is a transparent pressure sensitive adhesive that includes a crosslinked (meth)acrylate-based polymer and has a refractive index in the range of 1.45-1.55. The (meth)acrylate-based polymer includes alkyl (meth)acrylate monomers and may include acidic monomers.
