Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A lightweight wall covering having a weight of less than 14 ounces per square yard and having a substantially smooth inside surface and a deep textured outer layer comprising, a substrate having an exposed surface defining said inside surface, a fluid impervious film bonded against said substrate, and an embossed expanded vinyl plastisol bonded against said film and defining said textured outer layer, said textured outer layer being defined by alternating recesses and dense projections substantially free of air spaces said air spaces constituting less than 10 percent of the volume of said outer layer, said textured outer layer having a substantially fluid impervious skin, said substrate and film having a combined thickness of a particular amount of roughly 10 mils and less, and the outermost surfaces of said projections having a maximum thickness measured from the interface of said textured outer layer with said film which is within the range of roughly 3 to 12 times said particular amount and defines said deep texture in said outer layer.
