Abstract
Abstract A decorative wallcovering in roll form of the kind that is applied to the wall with adhesive, has a strength giving substrate ply (10), a mechanically foamed ply (11) having open and closed pores (13) with a decorative effect (12) on its exposed surface. A diffusion porous toughened surface (14) and print hold-out coat (15) is preferably provided before a printed decorative effect is applied. The print (12) may be hostile to the foam so long as the print application and drying is performed quickly. Texture effect can be achieved by selecting a substrate which has a degree of preferential absorption of one of the constituents of the foam in selected regions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
85 words
A decorative wallcovering in roll form for application to the wall with an adhesive, said wallcovering having a substrate ply which carries a mechanically foamed ply, characterized in that the foamed ply is one derived from an aqueous latex, has both open and closed pores, has a toughened and porous surface and has outwardly facing decoration, and in that the substrate ply is thin, strength-giving, dimensionally stable, and primarily nonselectively absorbent to the constituents of the foam to provide a low stretch paste-the-wall strippable wallcovering.
Claim 2
Dependent Claim
85 words
A decorative wallcovering in roll form for application to the wall with an adhesive, said wallcovering having a substrate ply which carries a mechanically foamed ply, characterized in that the foamed ply is one derived from an aqueous latex, has both open and closed pores, has a toughened and porous surface and has outwardly facing decoration, and in that the substrate ply is thin, strength-giving, dimensionally stable, and primarily nonselectively absorbent to the constituents of the foam to provide a low stretch paste-the-wall strippable wallcovering.
Claim 3
Dependent Claim
60 words
A wallcovering as claimed in claim 1 in which the toughened and porous surface has a print hold-out coat, the thickness of the wallcovering is in the range of 0.3 to 1.0 mm, the foamed ply is at least twice the thickness of the substrate ply, and the hold-out coat is less than one-tenth the thickness of the foamed ply.
Claim 4
Dependent Claim
26 words
A wallcovering as claimed in claim 1 in which the decoration comprises inks having solvents hostile to the foamed ply but rendered non-hostile by fast drying.
Claim 5
Dependent Claim
82 words
In combination with a wall, a decorative wallcovering having a substrate ply which carries a mechanically foamed ply, characterized in that the substrate ply is pasted to the wall, thin, strength-giving so as to be strippable as a piece, dimensionally stable, and primarily non-selectively absorbent to the constituents of the foam, and in that the foamable ply is one derived from an aqueous latex, has both open and closed pores, has a toughened and porous surface, and has outwardly facing decorative effect.
Claim 6
Dependent Claim
82 words
In combination with a wall, a decorative wallcovering having a substrate ply which carries a mechanically foamed ply, characterized in that the substrate ply is pasted to the wall, thin, strength-giving so as to be strippable as a piece, dimensionally stable, and primarily non-selectively absorbent to the constituents of the foam, and in that the foamable ply is one derived from an aqueous latex, has both open and closed pores, has a toughened and porous surface, and has outwardly facing decorative effect.
Claim 7
Dependent Claim
60 words
A combination as claimed in claim 4 in which the toughened and porous surface has a print hold-out coat, the thickness of the wallcovering is in the range of 0.3 to 1.0 mm, the foamed ply is at least twice the thickness of the substrate ply, and the hold-out coat is less than one-tenth the thickness of the foamed ply.
Claim 8
Dependent Claim
26 words
A combination as claimed in claim 4 in which the decoration comprises inks having solvents hostile to the foamed ply but rendered non-hostile by fast drying.
Claim 9
Dependent Claim
43 words
A wallcovering as claimed in claim 1 in which the decorative effect is produced, at least in part, by having a substrate ply of selected preferential absorption in selected regions of one of the constituents of the foamed ply to create textured differences.
Claim 10
Dependent Claim
22 words
A wallcovering as claimed in claim 1 in which dye receptive resins are exposed prior to the application of the decorative effect.
Claim 11
Dependent Claim
18 words
A wallcovering as claimed in claim 1 having an emboss applied to the foam in the gelled state.
Claim 12
Dependent Claim
21 words
A wallcovering as claimed in claim 9 including tip and valley printing of a pigmented foam to generate multi-colour relief product.
Claim 13
Dependent Claim
22 words
A wallcovering as claimed in claim 1 in which the substrate ply is a wet-laid non-woven or spun-bonded product devoid of pretreatment.
