Abstract
Abstract A self-adhesive wall covering or the like that is easily removable from a wall. The wall covering 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: 12
Claim 1
Independent Claim
98 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 pattern on one surface thereof; an acrylic-saturated paper having one surface adhesively fixed to the other surface of said fabric; a layer of PVA adhesive coated onto the other surface of said acrylic-saturated paper; and a layer of release paper removably secured to said PVA adhesive such that when said release paper is removed to expose said PVA adhesive, the wall covering is adherable to a wall by means of the exposed PVA adhesive.
Claim 2
Dependent Claim
98 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 pattern on one surface thereof; an acrylic-saturated paper having one surface adhesively fixed to the other surface of said fabric; a layer of PVA adhesive coated onto the other surface of said acrylic-saturated paper; and a layer of release paper removably secured to said PVA adhesive such that when said release paper is removed to expose said PVA adhesive, the wall covering is adherable to a wall by means of the exposed PVA adhesive.
Claim 3
Dependent Claim
32 words
The invention of claim 1 wherein said acrylic-saturated paper is white acrylic-saturated paper to avoid interference in the observation of the visible pattern when said wall covering is adhered to the wall.
Claim 4
Dependent Claim
14 words
The invention of claim 1 wherein said PVA 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
112 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; forming on one surface of said web of fabric a visible pattern; providing a web of acrylic-saturated paper; coating one surface of said acrylic-saturated paper with a layer of glue; pressing the other surface of said fabric and the glue-coated surface of said acrylic-saturated paper together to adhesively fix said web of fabric to said web of acrylic-saturated paper; coating the other surface of said acrylic-saturated paper with a layer of PVA adhesive; and releasably adhering a web of release paper to the layer of PVA adhesive.
Claim 7
Dependent Claim
112 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; forming on one surface of said web of fabric a visible pattern; providing a web of acrylic-saturated paper; coating one surface of said acrylic-saturated paper with a layer of glue; pressing the other surface of said fabric and the glue-coated surface of said acrylic-saturated paper together to adhesively fix said web of fabric to said web of acrylic-saturated paper; coating the other surface of said acrylic-saturated paper with a layer of PVA adhesive; and releasably adhering a web of release paper to the layer of PVA adhesive.
Claim 8
Dependent Claim
14 words
The invention of claim 5 wherein said PVA adhesive is a water-based polyvinyl acetate.
Claim 9
Independent Claim
106 words
A method of producing a wall covering adapted to adhere to and be easily removed from a wall, comprising the steps of: forming on a surface of a web of fabric plural rows of visible patterns; glueing to the other surface of said fabric a web of acrylic-saturated paper; coating the exposed surface of said acrylic-saturated paper with a layer of PVA adhesive; applying to said layer of PVA adhesive a removable web of release paper thereby forming a laminate; and slitting the laminate of fabric, acrylic-saturated paper and release paper longitudinally to form individual multiple-layered webs each corresponding to a respective row of visible pattern.
Claim 10
Independent Claim
106 words
A method of producing a wall covering adapted to adhere to and be easily removed from a wall, comprising the steps of: forming on a surface of a web of fabric plural rows of visible patterns; glueing to the other surface of said fabric a web of acrylic-saturated paper; coating the exposed surface of said acrylic-saturated paper with a layer of PVA adhesive; applying to said layer of PVA adhesive a removable web of release paper thereby forming a laminate; and slitting the laminate of fabric, acrylic-saturated paper and release paper longitudinally to form individual multiple-layered webs each corresponding to a respective row of visible pattern.
Claim 11
Dependent Claim
33 words
The method of claim 7 wherein said step of glueing said web of acrylic-saturated paper to said fabric comprises coating said web with glue and passing said web and fabric between heated rolls.
Claim 12
Dependent Claim
26 words
The method of claim 7 wherein said step of coating said acrylic-saturated paper with said PVA adhesive comprises rolling said PVA adhesive onto said acrylic-saturated paper.
