The use of an internally plasticized vinyl chloride film and a fabric backing, preferably a nonflame retardant fabric backing, as the substrate in a vinyl film/substrate laminate yields a product having a lower rate of smoke generation when burned than is produced by a conventional laminate of an externally plasticized vinyl film and a fabric backing. The internally plasticized vinyl chloride resin used in the vinyl film of the laminate of this invention may be a copolymer comprising from about 50% to about 85%, by weight, vinyl chloride, from about 3% to about 47%, by weight, of a C6-C10 alkyl acrylate, and from about 47% to about 3%, by weight, of a bis(hydrocarbyl)vinylphosphonate. The vinyl film/substrate laminate of the present invention is useful as an upholstery product. |
