  • Publication number: 20170267014
    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.

  • Patent number: 9289962
    Abstract: Laser-personalizable security articles include a multi-layer security document and an optically transparent processing tape. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser. The optically transparent processing tape sufficiently wets out on the misconstructured surface to render the microstructured surface invisible to a writing laser.
