  • Patent number: 5725947
    Abstract: The invention relates to a film composite comprising a thin flexible backing bearing a first layer of adhesive comprising a blend of from 10-99 wt. % of an acrylic latex and from 1 to 90 wt. % of heat-activatable urethane latex, and a second adhesive layer applied on top of said first adhesive layer comprising a pressure-sensitive adhesive exhibiting an initial adhesion as to allow reliable positioning and initial removability of said film composite on a substrate and an adhesion build-up to permanently bond the film composite to the substrate after a prolonged dwell time. The invention further-more relates to the use of a film composite comprising a thin flexible backing bearing a first adhesive layer comprising a blend of from 10-99 wt. % of an acrylic latex from 1 to 90 wt.

  • Patent number: 5229207
    Abstract: A film composite has a thin flexible decorative backing bearing a layer of adhesive which affords good repositionability and yet can become permanently bonded to highly plasticized substrates such as vinyl films containing migratable monomeric plasticizers. Such substrates include wall coverings and vinyl coated fabrics. The adhesive is a blend of an acrylic latex adhesive and a heat-activatable urethane latex adhesive, which blend has been coated onto the backing from an aqueous emulsion. Useful backings include vinyl, polyurethane, and polyolefin films.
