Adhesive-backed film composite which can become permanently bonded to a plasticized substrate.

摘要

A film composite has a thin flexible polymeric backing bearing a layer of adhesive which is an acrylic emulsion polymer that is resistant to migratable monomeric plasticizer. A preferred adhesive is a copolymer of ethyl acrylate, n-butyl acrylate, and acrylic acid. Even though it may be nontacky or lightly tacky, it adheres under fingertip pressure to, and can remain permanently bonded to, highly plasticized substrates such as vinyl films containing migratable monomeric plasticizers. Such substrates include vinyl coated papers, fabrics, and scrims. Useful backings include vinyl, polyurethane, and polyester films.
