Abstract
A wall covering having a stain resistant outer surface comprises a reinforcing backing layer, an opaque vinyl polymer surfacing layer overlying a front surface of the backing layer, a layer of printing applied to the surfacing layer in selected areas to form a desired decorative pattern to the wall covering, and a stain resistant transparent top coating overlying the layer of printing and imparting stain resistant properties to the exposed outer surface of the wall covering. The top coating is comprised of at least one transparent vinyl polymer, a flattening pigment imparting a substantially non-glossy matte finish to the coating surface, and from about 0.1 to 4 percent by weight of a perfluoroalkyl copolymer, preferably a perfluoroalkyl methacrylate copolymer.
Claims10
A stain resistant wall covering comprising
- a reinforcing backing layer,
- a surfacing layer formed of a polymer coating overlying a front surface of said backing layer,
- a layer of printing applied to said surfacing layer in selected areas and imparting a desired decorative pattern to the wall covering, and
- a stain resistant transparent top coating overlying said layer of printing and imparting stain resistant properties to the wall covering, said top coating comprising at least one polymer derived from vinyl monomers and from about 0.1 to 4 percent by weight of a perfluoroalkyl polymer, and a flattening pigment for imparting a non-glossy matte finish to the top coating.
A stain resistant wall covering comprising
- a reinforcing backing layer,
- a pigmented substantially opaque vinyl polymer surfacing coating overlying one surface of said reinforcing coating,
- a layer of printing applied to said vinyl polymer surfacing coating in selected areas and imparting a desired decorative pattern to the wall covering, and
- a stain resistant transparent top coating overlying said layer of printing and said vinyl polymer surfacing coating and imparting stain resistant properties to the wall covering, said top coating comprising a blend of a transparent vinyl polymer and from about 0.1 to 4 percent by weight of a perfluoroalkyl polymer, and a flattening pigment for imparting a non-glossy matte finish to the top coating.
A stain resistant wall covering comprising
- a reinforcing backing layer,
- a surfacing layer formed of a pigmented, substantially opaque polymer coating overlying a front surface of said backing layer,
- a layer of printing applied to said surfacing layer in selected areas and imparting a desired decorative pattern to the wall covering, and
- a substantially non-glossy stain resistant transparent top coating overlying said layer of printing and imparting stain resistant properties to the wall covering, said top coating comprising at least one transparent vinyl polymer, a flattening pigment in an amount sufficient to impart to the top coating a substantially non-glossy finish with a 60.degree. gloss meter reading of no more than 8 percent, and from about 0.1 to 4 percent by weight of a perfluoroalkylmethacrylate polymers.
