Abstract
Abstract A self-adhesive wall covering or the like that is easily removable from a wall. The wall convering consists essentially of a laminate structure formed of a layer of fabric having a visible pattern on one side and an acrylic-saturated paper adhesively fixed to the other side. A layer of PVA adhesive is coated onto the acrylic-saturated paper and a layer of release paper is secured to the PVA adhesive as protection and to prevent inadvertent adhesion of the laminate wall covering to a surface. When the release paper is removed, the PVA adhesive is exposed and serves as the medium by which the wall covering adheres to the wall.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
116 words
A self-adhesive wall covering or the like that is easily removable from a wall, consisting essentially of: a layer of fabric having a visible surface thereon; a barrier paper having one surface adhesively fixed to the other surface of said fabric; a layer of pressure sensitive adhesive coated onto the other surface of said barrier paper and prevented by said barrier paper from leaching through said fabric to interfere with said visible surface; and a layer of release paper removably secured to said pressure sensitive adhesive such that when said release paper is removed to expose said pressure sensitive adhesive, the wall covering is adherable to a wall by means of the exposed pressure sensitive adhesive.
Claim 2
Dependent Claim
116 words
A self-adhesive wall covering or the like that is easily removable from a wall, consisting essentially of: a layer of fabric having a visible surface thereon; a barrier paper having one surface adhesively fixed to the other surface of said fabric; a layer of pressure sensitive adhesive coated onto the other surface of said barrier paper and prevented by said barrier paper from leaching through said fabric to interfere with said visible surface; and a layer of release paper removably secured to said pressure sensitive adhesive such that when said release paper is removed to expose said pressure sensitive adhesive, the wall covering is adherable to a wall by means of the exposed pressure sensitive adhesive.
Claim 3
Dependent Claim
13 words
The invention of claim 1 wherein said barrier paper is white acrylic-saturated paper.
Claim 4
Dependent Claim
15 words
The invention of claim 1 wherein said pressure sensitive adhesive is a water-based polyvinyl acetate.
Claim 5
Dependent Claim
15 words
The invention of claim 1 wherein said fabric consists essentially of a polyester and cotton.
Claim 6
Dependent Claim
101 words
A self-adhesive wall covering or the like that is easily removable from a wall and formed by the process of: providing a web of fabric; providing a web of barrier paper; coating one surface of said barrier paper with a layer of glue; pressing a surface of said fabric and the glue-coated surface of said barrier paper together to adhesively fix said web of fabric to said web of barrier paper; coating the other surface of said barrier paper with a layer of pressure sensitive adhesive; and releasably adhering a web of release paper to the layer of pressure sensitive adhesive.
Claim 7
Dependent Claim
101 words
A self-adhesive wall covering or the like that is easily removable from a wall and formed by the process of: providing a web of fabric; providing a web of barrier paper; coating one surface of said barrier paper with a layer of glue; pressing a surface of said fabric and the glue-coated surface of said barrier paper together to adhesively fix said web of fabric to said web of barrier paper; coating the other surface of said barrier paper with a layer of pressure sensitive adhesive; and releasably adhering a web of release paper to the layer of pressure sensitive adhesive.
Claim 8
Dependent Claim
15 words
The invention of claim 5 wherein said pressure sensitive adhesive is a water-based polyvinyl acetate.
Claim 9
Dependent Claim
13 words
The invention of claim 5 wherein said barrier paper is an acrylic-saturated paper.
Claim 10
Independent Claim
90 words
a method of producing a wall covering adapted to adhere to and be easily removed from a wall, comprising the steps of: forming a web of fabric; glueing to the one surface of said fabric a web of barrier paper; coating the exposed surface of said barrier paper with a layer of pressure sensitive adhesive; applying to said layer of pressure sensitive adhesive a removable web of release paper thereby forming a laminate; and slitting the laminate of fabric, barrier paper and release paper longitudinally to form individual multiple-layered webs.
Claim 11
Independent Claim
90 words
a method of producing a wall covering adapted to adhere to and be easily removed from a wall, comprising the steps of: forming a web of fabric; glueing to the one surface of said fabric a web of barrier paper; coating the exposed surface of said barrier paper with a layer of pressure sensitive adhesive; applying to said layer of pressure sensitive adhesive a removable web of release paper thereby forming a laminate; and slitting the laminate of fabric, barrier paper and release paper longitudinally to form individual multiple-layered webs.
Claim 12
Dependent Claim
33 words
The method of claim 8 wherein said step of glueing said web of barrier paper to said fabric comprises coating said web with glue and passing said web and fabric between heated rolls.
Claim 13
Dependent Claim
27 words
The method of claim 8 wherein said step of coating said barrier paper with said pressure sensitive adhesive comprises rolling pressure sensitive adhesive onto said barrier paper.
Claim 14
Dependent Claim
15 words
The method of claim 8 wherein said pressure sensitive adhesive is a water-based polyvinyl acetate.
Claim 15
Dependent Claim
13 words
The method of claim 8 wherein said barrier paper is an acrylic-saturated paper.
