Abstract
Abstract Disclosed is a process for bonding wallpaper to a wall insulation board or film of a foamed organic polymer, comprising the steps of providing a layer of wall insulation comprising a foamed organic polymer; providing a layer of wallpaper; applying to the surface of either the layer of wall insulation or the layer of wallpaper a coating of an adhesive composition suitable for bonding the layers together, wherein the adhesive composition comprises an amount of a flame retardant agent sufficient to render the adhesive composition flame retardant; and bonding the layer of wallpaper to the layer of wall insulation. Also disclosed is a composite sheeting produced by this process.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
A process for bonding wallpaper to a wall insulation board or film of a foamed organic polymer, comprising the steps of: providing a layer of wall insulation consisting essentially of a foamed polystyrene; providing a layer of wallpaper; applying to the surface of at least one of said layer of wall insulation or said layer of wallpaper a coating of an adhesive composition suitable for bonding said layers together, wherein said adhesive composition consists essentially of water, a polysaccharide derivative as the bonding component and an amount of a flame-retardant agent sufficient to render said adhesive composition flame-retardant; and bonding said layer of wallpaper to said layer of wall insulation.
Claim 2
Dependent Claim
110 words
A process for bonding wallpaper to a wall insulation board or film of a foamed organic polymer, comprising the steps of: providing a layer of wall insulation consisting essentially of a foamed polystyrene; providing a layer of wallpaper; applying to the surface of at least one of said layer of wall insulation or said layer of wallpaper a coating of an adhesive composition suitable for bonding said layers together, wherein said adhesive composition consists essentially of water, a polysaccharide derivative as the bonding component and an amount of a flame-retardant agent sufficient to render said adhesive composition flame-retardant; and bonding said layer of wallpaper to said layer of wall insulation.
Claim 3
Dependent Claim
24 words
A process as claimed in claim 1, wherein said flame retardant agent comprises a flowable particulate composition which is soluble or dispersible in water.
Claim 4
Dependent Claim
16 words
A process as claimed in claim 1, wherein the polysaccharide derivative comprises a water-soluble cellulose ether.
Claim 5
Dependent Claim
31 words
A process as claimed in claim 1, wherein the adhesive composition contains between about 20 and 80% by weight of the flame retardant, relative to the bonding portion of the adhesive.
Claim 6
Dependent Claim
74 words
A composite sheeting for covering walls, consisting essentially of a base layer of a foamed polystyrene, a layer of adhesive contiguous to said base layer, and a layer of wallpaper contiguous to said adhesive layer, wherein the adhesive layer applied between the base layer and the wallpaper layer consists essentially of a polysaccharide derivative as the bonding agent and an amount of a flame-retardant sufficient to impart a flame-retardant effect to said composite sheeting.
Claim 7
Dependent Claim
74 words
A composite sheeting for covering walls, consisting essentially of a base layer of a foamed polystyrene, a layer of adhesive contiguous to said base layer, and a layer of wallpaper contiguous to said adhesive layer, wherein the adhesive layer applied between the base layer and the wallpaper layer consists essentially of a polysaccharide derivative as the bonding agent and an amount of a flame-retardant sufficient to impart a flame-retardant effect to said composite sheeting.
