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.
