A multi-layer sheet material comprises a film, and adhesive layer and an optional release liner. The film is a polyester blend comprising first and second polyesters that are substantially amorphous and possess certain physical properties including softening temperature, E-modulus, elongation and residual stress.

Composite film and use thereof in the presence of solvents

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.
